Cryptographers Find Fault With Palladium
FrzrBrn writes "Whitfield Diffie and Ronald Rivest raised concerns about Microsoft's Next-Generation Secure Computing Base (formerly Palladium) at the RSA Conference in San Francisco on Monday. They are (naturally) concerned about vendor lock-in and having computers turned against their owners. See the story at EE Times."
...Cancer researchers found fault with Marlboro brand cigarettes. More details soon.
then someone finds fault with it later.
And now we're supposed to trust 'Trusted Computing'?
You think that I'm crazy, you should see this guy!
Diffie and Rivest have always held the idea that personal privay (and personal security) is a fundamental right. Their comments at this forum pretty much express that.
They're cautious for a good reason. Making every PC an Xbox with push content delivery just opens up an ugly vulnerability in your system. I can't wait for the distributed Palladium cracking project!
From accounts of Microsofts other presentations they are there primarily to advertise the future of their technology rather than to actually discuss the future of security with others.
They are (naturally) concerned about vendor lock-in and having computers turned against their owners.
This will give the whole "man over machine" persona to Palladium, thus making it unpopular.
w00t!
Diffie and Rivest had better watch out! Microsoft could easily hit them with DMCA violation charges for questioning Palladium's encryption!

News Flash: "Blue screen of death kills computer and user, details at 9" - Kent Brockman
The inventors of the RSA algorithm (Ron Rivest, Adi Shamir, and Len Adleman) were awarded the Turing Award on Monday. This was announced at the opening of the RSA conference. More information can be found in this article.
Does anyone think Microsoft would have it any other way?
but due to DMCA laws cannot tell anyone about it, and therefore the faults will never be fixed, because the schmuckos the programmed the damn thing are too damn stuborn, and full of themselves to admit to there being faults in their code, and refuse to fix anything without proof of the faults first.

In Microsoft's NGSCB approach, users would have to consciously evoke a secure operating mode that would be turned off by default.
Now as we all can imagine, it won't take long before various applications will not work unless Paladium's controls are in effect. Anything that accesses potentially copyrighted works are the most likely to begin with. Windows Media player, E-Books, and later Office products will be the first to require this.
Microsoft is already pushing to get their media formats to be the default. Websites are frequently given discounted access to Windows Media creation software. Colleges and other low-budget places are frequently targets. They have to agree to use only those formats, not quicktime or MPEG, in return. This forces users to get Windows Media player to watch this content. Later MS will require these sites start saving in the newer, Paladium-only, versions, and we'll have our transition to lockout today.
What can you do to prevent this? Stay with open formats. Ogg-Vorbis. MPEG. XML/OpenOffice.org.
It'll be very interesting to see if this subtle push backfires or succeeds. Ten years ago, there's no doubt Microsoft would have been able to back us into any corner they wanted. But the last few has shown some strong distrust - people no longer take MS's word as law.
Let's hope that trend continues.
Which means it will only work on approved hardware - guess who profits from approving the hardware and drivers? Why would I need a secure framebuffer exactly when I'm already in full control of the code executed on my machine?
Seriously though, read the following:
"The right way to look at this is you are putting a virtual set-top box inside your PC. You are essentially renting out part of your PC to people you may not trust..."
Aren't people who download Kazaa already doing that, since Brilliant Digital's spyware is installed with the program and can use the computer's CPU cycles and hard drive space without warning? It seems that unless there is a big enough hoopla made about Palladium, unsuspecting customers will have no idea of "Trusted Computing"'s true effects and limitations on usage. Just ask a non computer geek Kazaa user if they're concerned that Brilliant Digital has so much control over their computer, and if they give you a response other than a blank stare accompanied with a "wha?" I'll give you a Gummy bear (It's warm from being in my pocket).
Whitfield Diffie, who holds the position of Distinguished Engineer at Sun Microsystems Laboratories is best known for his 1975 discovery of the concept of public key cryptography, for which he was awarded a Doctorate in Technical Sciences (Honoris Causa) by the Swiss Federal Institute of Technology in 1992.
For a dozen years prior to assuming his present position in 1991, Diffie was Manager of Secure Systems Research for Northern Telecom, functioning as the center of expertise in advanced security technologies throughout the corporation. Among his achievements in this position was the design of the key management architecture for NT's PDSO security system for X.25 packet networks.
Diffie received a Bachelor of Science degree in mathematics from the Massachusetts Institute of Technology in 1965. Prior to becoming interested in cryptography, he worked on the development of the Mathlab symbolic manipulation system --- sponsored jointly at Mitre and the MIT Artificial Intelligence Laboratory --- and later on proof of correctness of computer programs at Stanford University.
Since 1993, Diffie has worked largely in public policy, in the area of cryptography. He has testified twice to the House and twice to the Senate. His position --- in opposition to limitations on the business and personal use of cryptography --- has been the subject of articles in the New York Times Magazine, Wired, Omini, and Discover. The subject has also been covered on the Discovery Channel, Equinox TV in Britain, and the Japanese TV network NHK.
Notariety has provoked a number of awards, including: IEEE Information Theory Society Best Paper Award for 1979, IEEE Donald E. Fink award for 1981, the 1994 Pioneer Award, given by The Electronic Frontiers Foundation for contribution to the quality of life in cyberspace, the 1996 National Computer Systems Security Award given jointly by NIST and NSA, the 1997 Louis E. Levy Medal from the Franklin Institute in Philadelphia, the First ACM Paris Kanellakis Award for contribution to theory and practice in computer science, the IEEE Information Society Golden Jubilee Award for invention of the Diffie-Hellman key exchange protocol.

To understand why this is not a good thing, imagine if a commercial company had the monopoly of passport and driving license production, and were able to prevent you from using the ID they issued to verify who you were except in "microsoft approved" shops and venues (or countries).
IDs and trust systems should be standards based, not proprietary. They should be secure, and openly peer-reviewed or audited. And the ID should be under the control of the person being identified (or at least issued by a "neutral" government body, as passports are now).
But I've just started thinking about this... so I might change my mind some more. Would that make me a bad slashdotter?

Score: -1 100% Flamebait
Wittfield Diffie is an engineer at Sun Microsystems, one of the only corporations that can be considered a Microsoft competitor. Ron Rivest is a professor as his day job, but gets quite a bit of cash from RSA, and Microsoft isn't using any of the code that RSA provides (BSAFE, etc) in Paladium, so that's a big chunk of change that won't be coming his way.
We here on slashdot may realize that Rivest and Diffie are actually quite excellent individuals in their field, but these kinds of conflicts of interest are frequently what will be pulled out to counter an argument, rather than working from the facts themselves.
The headline of this story is misleading. Some people disagree philosophically with Palladium's goals, not its technical merits. It just happens that these people are famous cryptographers. At the moment, the technical details seem sparse, so we'll just have to wait until they are released (if ever) to see if the goals that are mentioned are actually met.
Didn't Asimov write up a list of directives for robots, and wasn't one of them that robots should always be subservient to humans?
1. Is palladium optional for the SO? Could Linux or Winshit98 be installed on a Palladium box w/ no ill effects?
2. Is palladium optional for developers? Can "Joe Shareware" still release his software w/out paying an evil corporation for the right to sell it?
3. Is there any way whatsoever in which this would help Joe User or Joe Hacker(not to be confused with Joe Cracker)?
4. Will this be integrated on Sparc and PowerPC or just PCs? Is AMD accepting this BS or just Intel?
5. Who will be in charge of licensing keys for palladium software?
You can't judge a book by the way it wears its hair.
if foreign governments are having misgivings about using Windows because it is closed source, they surely won't accept Palladium if MS has undue influence and control over the architecture.
smd4985
Just as a note, contrary to what most people's initial reaction is, the article does not talk about any cryptographic flaw in the system. Diffie is arguing the merits(or lack thereof) of a system that the user doesn't hold the key to; Palladium itself hasn't been proven insecure(yet).
It's not much of a change from now: you don't own your copies of windows nor do you own your XBOX
I hate to take this stance, but the above says it all. Just like the vast majority of /. that would rather post than write to their representatives, Palladium will simply be buzzworded and adopted by the masses. Regardless of how the technical community kicks and whines, the forces of market domination will likely persevere.
Palladium was intended to be a joint hardware and software excercise. Where you could only run signed code on your boxen. I didn't really understand how this could be benificial as it would basically halt any and all software development (new piece of code has to get signed digitally before it can be run. Can you imagine how frustrating that would be for a coder???). Also, forget about recompiling your kernel, once it's changed, you need to get it re-signed before you can use it to boot.
If MS has it's way with palladium, it will be just like the XBox now where you must pay MS for the boot key for a game to work. I dare say that not only was the XBox an attempt to get into the console market, but also a testing ground for palladium. Given the dismal failure of the XBox so far, this could also explain the truckloads of cash that MS has been burning on the XBox. They WANT Palladium to work and will do anything to make sure it DOES work. It is their final chance to secure complete market domination inside the law before linux makes it's way onto mainstream desktops.
All I can suggest with this sorry state of affairs is to change your hardware now to an etirely different platform. (gamer's won't like this) Move away from x86. There are many architecture's out there that would both benefit from incresed use and R&D funding. Names such as Alpha, SPARC, and my personal favourite, PowerPC are all perfectly good systems, and as we all know, run linux and BSD. So, choose your processor, choose your OS, GET SOME APPS COMPILED FOR THEM! and make a stand to let MS know that you own your systems and that all your boxen are NOT belong to them. Stop talking about it and do something for a change. I have I run a MS-free iBook with OSX and X11 and have never been happier

Is there any way whatsoever in which this would help Joe User or Joe Hacker(not to be confused with Joe Cracker)?
The excuse given for the CBDTPA, which may apply to Pd as well, is that more authors would be willing to publish works in a digital restrictions management system than in a system that grants all fair use rights by default.

The fact is, there has never been enough damage to home computer systems to warrent any sort of cryptographic systems such as that which microsoft is describing. How many people could say that because of some random person on the net or in a chat room they lost all of thier data? The worst offenders in these regards are COMPANIES, spy-ware, ad-ware, crappy patchs that break the system, and yes, even DRM schemes are the cause of most of our headaches. So microsoft's proposed solution is to say that they as the worst offenders of crapping out our systems are the only ones who should hold the keys to fix it? Microsoft who gets into bed with the RIAA by extolling the virtues of how great the copy protection systems of windows is, they expect us to trust that they won't lock us out first chance they get? Microsoft who has thier windows media player try to "phone home" through OUR lines without paying us for it, sending our personal data...we should trust these people with their "trusted computing" ??? This is madness, if MS tries to impliment this, i'm going 100% linux because i'll have no choice, if pentium and amd refuse to offer a chip which is not palladium or a similar system compatible, then i will refuse to upgrade for as long as humanly possible, or i'll attempt to get a hold of another type of chip. I don't know if the rest of slashdot has cottoned on, and for those of you that post in the RIAA and in Microsoft's denfense, this is war you know, there are no guns, and there are no bullets, but they're attacking our minds, they are going to chain us up and throw away the key, we see example after example after example. I can't beleive how lightly this is going over, think 50 years down the road of us laying down and taking this...where will we be? are they going to start bar-coding us and deducting 50 dollars directly from our pay cheque because of our alleged piracy? You say "no, that's being stupid" well considering what they've done already, and what's in the works that we know about, can you really say that it is all that dumb? These are scary times, and we need to fully wake up and realize exactly what sorts of things are happeneing around us.
They found fault with the way the computer has more control than the user. They didn't find a crytographic fault in any of the protocols.

Trusted Computing FAQ | Free Dawit Isaak!
Optional as in you won't need it if you don't want to [use any new copyrighted works]
You assume that all authors would switch over to a digital restrictions management system. This may be true of the studios in the Motion Picture Association of America, but there remains a thriving community built around limited free sharing of copyrighted works, especially computer programs.
And if you claim that free software won't be allowed to boot on future computers, I don't find that substantiated. What I've read of the Palladium specification states that Palladium comes into play only when the system is booted with Palladium support turned on in the BIOS, and only for those processes that import palladium.dll. From Microsoft's marketing material: "A 'Palladium'-enhanced computer must continue to run any existing applications and device drivers." And the TCPA TPM FAQ (pdf) states that "The trust model the TCPA promotes for the PC is: the owner runs whatever OS or applications they want".

Going to a DRM OS will change how personal computers work. People aren't always happy with change, and if forced to, they will review their options. That would be the perfect time for a Linux distro that does a painless install/conversion for Windows users, and installs a "best of breed" set of packages that are either compatable or equivilent to MS Office and friends. (If you really want 101+ different editors, make it an option.)
With the right package at the right time, the MS DRM "trusted" OS could be Microsoft's PS/2.

Damn good point. Your comment gathers up and bundles rather nicely the hard cold facts. And of course, once MS has made this REQUIRED to use any software of any consequence, I am sure the price of Windows will jump again.
THIS is EXACTLY why I am working very hard to learn Linux on the Desktop and hone my *nix server skills as well. It isn't a matter of 'bad old MS' to me as much as it appears that they are on the verge of imploding, and they don't realize it. Its a simple matter that I think Linux will end up overtaking MS not on merit, but by simply having less DEmerits at the same time it becomes 'as good enough as'. When the change happens, I want to be up to speed, and ready to capitalize on it. (read: make $)
Free people don't like this kinda shit, it sounds so, well, unfree (as in speech). As the computer gets cheaper, windows gets more expensive, Linux gets better (RH9 is about as good as win95 to me, which is a compliment) it WILL put pressure on windows. Unlike others, I do NOT think that Linux will gain a percent of market share here and there. I think that it will happen in a very short period, BANG, and over 2 years, half of everyone is no longer using MS. History shows this is the most common method for change.
This is why I am not a MS basher (Really, I use Windows). I don't have to be, they are becoming their own worst enemy, and beginning in 2 or 3 years, they are going to be very shocked in a very short period of time.
Tequila: It's not just for breakfast anymore!
From what I have been reading this stuff is just blatant garbage... The idea of locking out the user is a totally STUPID idea.. for one, it would kill the open source movement.. because behemoth companies such as microsoft would just lock out the competition (bye bye sun). the government would even back this lunacy because its the law. so even cracking it would be illegal under the fascist DMCA. so whats next? Well, for us to combat this as a whole.. the first thing that would have to happen is all of us slashdot geeks get together and decide to actually vote and protest against this stuff and boycott against companines which support "you rent our equipment" and if the riaa gets in front of us, maybe we will need to strike them down... like with a chilling boycott (im talking tv ads to go with it) we can and we will win.
I believe you are incorrect... Last i checked, the way Palladium works is that data is trusted and encryped, not programs... and no doubt, you can run other OS's on your X86 hardware. To make linux on x86 impossible or harder would be retarded for AMD and intel. This is about securing data. Sure, programs are data...but they don't all have to be secure. You can run unsecured code. You can run a whole "insecure" OS, that just happens to be more secure that win_Palladium. BSD, Linux, will be FINE.
Who is this Anonymous Coward character, how does he post so much, and why is he always such a whore?
In spite of the imagined throngs of doe-eyed deer-in-the-headlights otherwise thoughtless "consumers" out there, it's going to come to pass that Microsoft and their greed will overextend itself. The lock-out we-control-your-security methodology will only work until even the more moronic people have been bitten by it. Perhaps too late for their immediate circumstances, even the most ignorant and go-with-the-flow types will realize they have to leave this Microsoft environment. I believe what we are seeing is two things (a) desperate paranoia-fueled greed and (b) the beginning of the end for anyone so foolish to be so exclusive to the world's computing community. Here on this forum, I keep hearing people talking in little boxes about Intel, Microsoft, AMD, Linux, PCs and all of this shit in this little world we have encased ourselves into. I used to be one of those people. While now I'm working much of my time in Linux (although Windows world stuff still pays some of the bills and mainframes pay the rest) I have gone to a point from being immersed in the Microsoft environments to now being largely outside of them. People? Notice that we are the majority. And we can choose whether or not to be consumer cattle thoughtlessly following the loudest noise. We can choose our own directions. But mental and philosophical freedom is hard work. Not going with the large groups of clueless cattle to slaughter means a lot of effort. If this philosophy of "security" is a bad thing, and I sincerely believe "Palladium" is a very bad thing, don't follow it. Just. Don't. It will have some nice bells and whistles, but recognize a gilded cage and a machine under perpetual remote control and remote authorization for what it is. Don't sit there whining about how Windows 98 or Linux is your favorite OS of choice--please get your egos out of this and start working on some of the deeper principles of your liberty and facility with your own data on your own computers. If it means developing GPL-equivalent hardware, open design microprocessors, and a true open and truly standard machine architecture, done somewhere in the world, then accept this as the direction. Locking people out means locking yourself from them. We have a greedy minority of producers locking out and constricting a vast majority of consumers. Linux demonstrates that we as people can produce, but most of us are in the software or user spheres. People? If they are so intent on locking us out with these obviously evil "security" schemes--let them! But don't let yourself ever be locked in. Linux and OSS is one way to freedom (like Richard Stallman's idea of Freedom as liberty--not lack of cost or price). But perhaps leaving Microsoft, Intel, "Wintel", and going to newer, more open and honest architectures is the way to go. Wintel is rotting and dying. Linux and it's philosophies of openness will succeed because they allow people freedom and the proliferation of new and open idea. Wintel is like the dinosaurs in a sense of being widespread and formidable in the small computer market. This chapter of overreaching greed is the first few pebbles of the beginning of a meteoric shift. Look for freedom and reject this and all attempts to hijack and tyrannize computing.
Microsoft is infact targeting the home users as well, but through content/service providers. Basicaly they are trying to provide a securied (for the provider mind you, not the end user) platform/enviornment where a provider of say, music files, or films for example can be sure that only software aproved by them will be running and able to use (play back) the data they provide.
For example company big$co wants to sell data file D to john doe. big$co gives a copy of D encrypted with the secret key on john doe's Palladium enabled comp to john. (notice i dont say John Doe's key as this is not the case. thats exactly what Rivest and Diffie are, rightly IMHO, complaining about.) The secret key in the box can only be accessed through the trusted OS (nexus) which in turn makes sure that only trusted software (i.e. some app provided (and sold) by big$co). Since the pladium part of the system will only boot if the nexus is trusted (i.e. hasnt been tampered with, and thus hashes to a predefined and stored value) and the nexus checks that only trusted software talks to it, the enviornment is controled by big$co and Redmond.
The reason i say this is how they are targeting the end user is because they are trying to create an environment which is favorable to content providers such as big$co. Thus there should then be more such companies, more offers, and more content. This in turn should provide some kind of killer ap (should as far as Microsoft is concerned ofcourse). And thus the end user now HAS to get a palladium comp, if they want all the content.
one problem with this setup which is partly what rivest and deffie were argueing, is that if john doesnt own his key, what if say he buys a new computer or his old one just plain breaks for example. all his payed for content becomes worthless. this is ofcourse mearly one example of what is so grossly wrong with all of this, never mind the moral issues that u dont own ur computer anymore.
Some guys with no credibility to lose, think they know better than the experienced and widely-known software professionals and security experts that created the world's most popular OS? Microsoft are the experts who came up with the idea of the world's most popular web browser, MSIE, which is so powerful that it can run a program on a web page, and is capable of secure internet connections to web sites! They make a very popular email client, and very, very powerful spreadsheet and word processor apps. They make a web server of which nearly thirty percent were completely protected from a rampaging worm a couple years ago -- think about how many thousands of computers withstood that malicious attack, and what might have happened to them if Microsoft hadn't been there with their valuable security patches.
That two nearly-anonymous net.dweebs nobody has ever heard of, would arrogantly say they know more than Gates, Balmer, and their crack team, is just preposterous.

"In Microsoft's NGSCB approach, users would have to consciously evoke a secure operating mode that would be turned off by default. New instructions in the CPU as well as changes in the memory controller would help carve out a protected space in main memory to load a small, secure operating system kernel. "
Correct me if I'm wrong, but hasn't *nix been doing this for oh say 30 years?
Palladium cannot stop viruses at all unless all "trusted" programs that could be told to execute the virus instructions actually can't do anything, which would mean the computer is useless. Outlook viruses work by doing things that the "trusted" program Outlook thinks are perfectly benign, the actions are harmful either due to bugs in Outlook or mistakes in it's design. All palladium does is "sign" the bugs in programs and then claim they are "trusted" as though that magically made the bugs go away. It provides no more help than the kernel-mode bit that is already in the hardware and is used by Linux and Windows and does not seem to have stopped viruses on either one of them.
The purpose of Palladium is for Digital Restrictions Management (DRM). There is NO other reason for Palladium. NONE. It's purpose is to make sure that certain programs (everything not written by MicroSoft) does not run on the machine.
The "target" audience is MicroSoft themselves. They are trying to make a machine that is acceptable for playing digital content, with a design that guarantees that alternative operating systems are totally unable to play this content. Far more reliable DRM systems (hardware cards) that would work under Linux are discouraged because of the bogus promises of Palladium.
The number of bits in the key is not the issue. In fact, most secure protocols like SSL use a decent size so that brute forcing is not worthwhile.
The point actually is that any theoretical construct like a cryptographic scheme or a TCP protocol needs practical implementation in code. And this is where the bugs creep in. And with things like Microsoft, those bugs are as common as snow in Greenland. And so all these hackers/crackers out there working their fingers on their keyboards and peering into bright screens into the fading night can 'hack' Palladium.
Microsoft has taken on itself to make errors wherever possible and remain as human as any one of us. Trust them to repeat their humanity and come up with enough holes in their Palladium implementation to let most hacks through.

Ummm, exactly WHY do you think the NSA seems to have suddenly stopped contributing code to the NSA security enhanced linux project?
;)
I suppose the NSA stopping all development on SE Linux is the reason that they just posted updates one week ago to SE Linux, as well as in January 2003, December 2002, and October 2002, all of which took place after this article reported them dropping the project (August 2002).
Not to flame, but just check your sources first next time
**AA: a bunch of mindless jerks who'll be the first against the wall when the revolution comes
Here's a go:
Palladium is very similar to what a minidish box or cable box is. For the home user, it's mean to secure a channel to your computer so that digital movies and music can be delivered to your system without you being able to steal it. The difference is that a computer downloading something from the internet can give feedback, whereas my dish network box can't (because I unplugged the phoneline from it).
The reason that this is causing a stir among security experts (and Rivest and Diffie are as expert as it gets. If they say Palladium is insecure, then there'll be hundreds of thousands of people who know in their bones that Palladium is insecure and won't take a second look at it, other than to frustrate themselves with lots of math) is because a computer isn't just a dumb satellite box. Your satellite box stores _no_ information about you. Depending on how you use your computer, it has an enormous amount of information about you on it. Banking information, sexual preferences, medical conditions, credit history, criminal history, and many other potentially embarassing or damaging bits of information are on your computer. For Palladium to work correctly, it'll be able to instantly tie you (as in your name, address, phone number, credit card number, social security number, etc) to any information that accidentally leaks off your computer. An example of this is the referrer tag in your internet browser. If you have javascript turned on, and you go from the goatse site to a site that you have to log into, then they can reference that information. It's not a matter of if they can do it, it's a matter of will they do it. Do you want to leave your information up to that?
This is only the tip of the iceburg. What people are really worried about isn't that your computer might leak information, it's that information might be actively taken from your computer. If you stream a song through Palladium, and Palladium thinks you tamper with it, is it going to send your name/address to the media company? Will that company try to extort a fine from you unless you can prove you didn't steal the song? Also, if an application is considered to be secure, are you more likely to dump information into it? If so, what happens when Palladium fails? Microsoft was convicted of being a monopoly for a reason. They don't care about you, they care about your money. They aren't really a company to trust, and the decisions they can make about how Palladium works on your computer are ridiculous.
For businesses, let's assume that Palladium is running on one hundred million computers worldwide (I've done this number bit before). Let's also say that it's flawed in a very minor way, such that 0.1% of the time a trusted application is opened in Palladium, it's marked as untrusted (or unlicensed or stolen or unpaid-for). Assuming each computer only opens one application per day, that's 100,000 daily errors. These errors can't be cleared automatically, because it'd flat be stupid to let errors go without checking on them. That means some call-in center has to resolve 100,000 problems per day. The operators for that service have to be paid, so there'd probably be a priority queue based on who's paid for the premium call in service (I'm not being verbose here because I'm sleepy). If your application errors during a critical presentation or a critical battery of tests, you're just plain fucked (the careful reader will note that this means that Palladium can't be trusted in critical roles, meaning it's already philosophically failed). A computer that might rebel against you is a risk. Furthermore, if there are false-negatives, then there will also be false-positives. Since computers are deterministic and the internet information exchange is so great, once someone find a false-positive, it will be exploitable. Bug free programs don't exist, and Microsoft is worse than usual at churning out bug-free code.
In summation, Palladium can't w

When you read that the user doesn't hold or control or own the keys to his computer, you naturally assume that someone else does. This is not true. No one owns the keys.
The keys are generated internally in the secure hardware. They are public and private keys, and the private keys never leave the chip. Neither Microsoft nor the user nor the chip manufacturer can get at those keys.
These keys are used by the secure hardware to lock data and to report a hash of an executing "secure" program. Because no one else has the key, neither the user nor Microsoft, no one can forge such a message (modulo the issue of breaking the hardware security).
This is how Trusted Computing has to work. If anyone could get access to the secure keys, then they could misuse them and make false statements with them, and there would be no trust and no security. Only by embedding the keys in a well-defined piece of hardware, with predictable and known behavior, can the keys serve to transfer trust to other software.
So when we see these complaints about the users not controlling their own keys, keep in mind that the point is not to put control in someone else's hands; it is to make it possible for the hardware to make trustworthy and believable cryptographic statements. The keys can't be owned or controlled by anyone, for this to work.
From TCPA / Palladium / NGCSB / TCG Frequently Asked Questions:
This means that this whole Palladium/TCPA monstrosity requires support from both hardware and software. It is entirely up to the end-user whether or not he wants this. However, senator Fritz Hollings of South Carolina is working on getting a law that will make TCPA mandatory, see here. Until such time that this bill becomes the law:
1. Don't buy the hardware. Unless there is a compelling reason to do so. Well if you are working for the military then go knock yourself out.
2. Don't buy^H^H^H lease/rent/license/WTF the software. There is no compelling reason to do so.
It will only be compelling to use Palladium/TCPA software and hardware only if it becomes illegal not to use it.
Secure computing is not the aim of Palladium/TCPA. Its aim is to provide a way for software peddlers like Microsoft and content pushers like Disney to monitor what you run on your computer and assert control over your computer. In the long run, it will provide them a way to assert control over you.
Secure computing can be achieved through a combination of secure computing practices, secure operating systems running secure applications, and plain-old common sense.
If Intel, Microsoft and their cohorts push through with this stupidity it could spell the end for them. Just think, why in the hell would I want to run this sort of crap? Unless it's mandated by law, there's no reason for me to do so. With the recent slew of news about stupid laws being implemented in the U.S. it's a real possibility.

Palladium whatever does not mean that the concept of using "software" on only one platform and you have to pay for on another platform is an open and shut case.
The CD's that I have I can play in my stereo, in my car, wherever. With media that is locked to one machine, I CANNOT use said media as I am used to.
Technlology like Palladium should be used EXCLUSIVELY to trusted computing (you know me and i know you..) I am master of my identity, media I buy should work on all my machines. Preventing this is an infringement of my rights and a denial of me as being my own master.
To put it in an scenario; I download (payed for) music, I burn a CD and I will be able to use it in my computer(s), stereo and car.
I am not my computer and my computer is not a customer.
Thanks,

How come i don't have this now allready, more then two years ago virus-researchers claimed virusses would soon (within 3 yrs.) be able to evade scanning techniques.
...
Would this mean fewer 'blue screens', fewer crashes, fewer halts, fewer bugfixes, fewer patches, fewer servicepacks, fewer windows updates ? Or
God NO, this would mean MORE of them !
Also, does this mean i'll have to do some extensive upgrading on my computer again ? It's quite hard to believe such an all-round solution would not ever put some extra load on my computer system.
Now i come to think of it, will i need Palladium Certified Hardware ? Will older hardware apply as well ?
Or do i just stick to good configuration and good software ? Or revert to encrypted letters by post ?

Heyyyy, that's great.
But what about this? . Really, don't be patting yourself on the back too much, or you will fall into the same pit that we have in the U.S. Some dumbass law will get passed wherever you live because your politicians are just as greedy as our politicians. They'll pass it under your nose, or through some back door, or right in front of your face. Then you will be just as screwed as we are.
People from other countries like to think that they are above laws like this. I hope you are right, because it will give me more options when I finally decide I have to leave this country. :-) Just make sure that while you are laughing at our stupid laws, the same ones don't get passed where you live.
Don't get me wrong, I was born here, but my eyes are open. Is the DMCA as bad as some of the human rights violations that occur around the world? No, of course not. But corporations run America, and there is little chance of that changing. I don't know how much longer I can take it.
My beliefs do not require that you agree with them.
And I do hope that your transition over to Linux goes well for you and your business. Best of luck.

there was a thread yesterday wherein many farkers were talking about how this action by MS was frustrating, and that they wanted to switch.

just a not-so geeky viewpoint there.
