    Exactly right. I had a customer that *really* wanted to get a specific WFW3.11 special machine control program to work on a later windows version, '98. There was no inexpensive or fast way to redo this, the original company who wrote the software was gone and they had no source. It was almost to the point of having it rewritten and killing an already fragile budget and deadline. This software was so vertical market it was dental floss.

    I have no idea where I found it or what it was called. It's all forgotten but some kind soul who'd done all the dirty work and left it laying around on the net for someone to find came to the rescue.

    It was I think shareware and it was hell finding them, eventually the company bought a license from them, several hundred actually.

    That was one shocked programmer. ;-)

    They even took the original software and did some extensive testing and updated the old product.

    It works like a charm, I don't have a clue how as I did not have the time to look at it other than to verify it worked.

    It is a pity Microsoft is so closed off, it was a gradual process to convert me from really liking their product to now, it started with win95 and

    Ok, you're statement really confused me, that's why the long winded post that follows this proper reply to your message.

    In your method I think you're using a OTP derived chunk as a symetrical key. You can of course have only two devices, the bios and a device on the motherboard that needs authentication to run but all you'd need is just the device and a call in the bios to it. See below for a description of a bit more vicious device.

    With either method there is still no protection for the goodies, who want's a corprate motherboard? Just pitch the computer out a window and go scavange the good stuff left. I've even seen PCs put in boxes for the 'trash man' and gutted right outside the business. This is why most companies crush stuff in a compactor. We won't discuss here the shipping of company property via FedEx, nope won't.

    I've lumped the original posts bios scheme in with Snake Oil because I think it fits. Without reasonably uncrackable 'host-server' authentication, reasonably uncrackable user authentication, blah, I don't see any benefit and a lot of http://www.stupidsecurity.com

    What I write below I leave, I think it's good but it isn't even close to what you were saying.

    ---beging long winded part---

    OTPs are the simplest type of encryption to explain and use and most absolute bitch to do right and maintain right. What I think you're stating here is a one time authentication pad (not sure if this is the right phrase but similar) and is a different use of a one time encryption pad and has the same pros and cons.

    If you want to use an actual OTP, you would need one bit of OTP for 1 bit of real world data.

    I had wrongly assumed you meant that the pad was internal to the computer and would only be used to authenticate that the computer was still in the hands of the gud and not the e-ville. What follows
    reflects that misassumption.

    It would need to be:

    A) big enough to outlast the life of the machine, now square this as computers never die they just get sealed up inside walls, ask Novell.

    B) A large enough chunk would have to be used to avoid positive collisions which means 32bits,
    64bits, 128bits, a dollar.

    C) Every computer would need a totally unique OTAP, this includes unique 'chunks'. I wanna see the bill for those bits from the radioactive source.

    D) No chunk can ever be used again, ever, period, never ever, repeat this till your jaw aches and you wanna puke from dehydration.

    C) It can't be a readable e/eeprom/flash but a device that cannot be read from, only queried and it has to have enough storage to mark which bits have been used or to just erase them. It cannot query any outside source to know which key to use. It just refuses to boot the computer on a failure, all tracking needs to be performed by the authenticating companies host.

    D) Once the computer is reported stolen the OTAP that the authorizing company has on file would need to be deactivated. I assume it would be possible to just log the IP, sound an alert and refuse to process the request since a honey pot trap is/was/maybe/willbe illegal.

    I'd like to see them print up the amount of waste and the life expectancy of each. How much nuclear waste will there be? How much will there be if recycling of this waste is allowed? Yes, even nuclear waste can be recycled.

    Compare this to coal and oil, how much waste is generated by these. How long does it remain? Since it's dumping is not as strictly controlled how long will it's effects last in the environment?

  8. Not bad but kinda cheep. on Phoenix Unveils Anti-Theft BIOS · · Score: 5, Interesting

    It's cheep security, None of the peripherals seem to be protected and that's the meat of any system.

    If you buy a used PC with that system in it you should have the ability to contact the maintainer of the system to work out ownership transfer. There should be no fee for this.

    Prediction by MrPredicter:

    One week after deployment a copy of the BIOS will be posted to usenet, Seventy Six Milliseconds after that it's cracked, patched and offered on WareZ sites with instructions on how to burn, unplug or desolder and install the new chip.

    Fixing the above, off the top of my head:

    Hardwired into the motherboard is a distributed encryption device that holds all of the motherboard chips, drives, ram and compatible installed cards in an inactive state until a USB or other device is insterted. The unlocking device needs to have been activated with a PIN prior to insertion so that the secret key inside can encrypt a challenge response with the devices in the computer. The device in the computer should also do realtime transparent encryption of the drives and offer network encryption as it would be trivial to add. Internal keys in the device would be the provence of the local IT security staff, they could not be changed by the user.

    One nice feature of this method is that, with a well setup OS each users network presence (data, settings, drives ect) could be transparently encrypted, each PC would be generic with no user or company data stored on the PC just on the network. Other networkable protocols could be implemented. I think Linux is close to part of this done in software.

    The device would need to be distributed, that way an attacker would have to compromise every device in the computer to make any use of the computer. Even the ram would not be of use.

    It would be possible to do this in a compatible way to protect the addons use extenders/risers that contain the encryption receivers which would be epoxied to circuit cards, drives and ram would slightly reduce cost and void warranties but allow easier upgrades by just adding a riser. The other method is to order specially modified hardware and only the Motherboard needs this. Yes, there are all sorts of drawbacks mostly stability issues and the CPU is stil not protected from theft.

    Isn't there some sort of specification for all this, this didn't just come to me a vacuum, well I vacuumed it up, most probably from the cypherpunks mailing list but can't remember.

    Total added cost to the PC, too much:

    Just hire a damned good degreed security specialist and a retain a good physical security consultantcy and let them work with a team of people to implement a reasonable security system and stick with it. Add to that good training for the security people and rigorous *reoccuring* background checks. Also a mid/upper level management that actually listens to the experts in this is needed, eviserate the dead weight as needed.

    Gold, silver, tobacco, bulk food goods, leather, fur and other items have all been used as money. Paper money has always been problematic both from the ability to deflate it remotely and the counterfeiting problem. Metal coins are harder and not immune, but there is an aura about gold and silver as coinage.

    While leather is still used as a trade good, well to wrap a trade good, I want gold and silver coins again. Since a dollar coin would be microscopic if gold, silver does as well.

    A 'US silver dollar' is worth around 5 - 8 paper dollars. It's still bulky but I can still spend them for the real value of the silver if not a bit more if the cashier is receptive, if the cashier is knowlegable it might be worth a paper dollar. ;-)

    The 1oz silver commemorative 'coins' don't work as well unless the cashier is knowledgable or if the design is cute, these are worth around 5 paper dollars. You're depending on the cashier to buy the coins and put paper money in the register so neither this or the US silver doller can be called an accurate currency but I can always spend them so they are widely accepted.

    What a local coin dealer calls 'junk silver' mercury and rosevelt dimes, silver quaters, those 1oz .999 fine slugs with pretty pictures are very affordable .

    I use them sometimes as tips, sometimes I try to get the value of them from a cashier, and I use them as gifts. The 1oz ones can be hammered into many silver rings and silver bells which increases their value. Though fake silver items and imported silver items have harmed this somewhat.

    The dimes are locally 35cents for rosevelt and 45cents for mercury. 1 paper dollar gets one silver quater. 5-8 paper dollars gets a silver dollar and 5 paper dollars gets a 1oz .999 fine slug coin with various stampings. State sales tax not included. As with any moneychanger selling these back to them incurs a loss and explains some authors of old texts loathing of them. I like the fellow I do business with as he is quite fair on the sale price and the buy back.
    Caveat Emptor.

    P.S. One thing I've noted, Mexican silver pesos from 1924 or so that say "Libertad Y Independencia" stamped in the smooth edge and are stamped 0.720 (72 percent) silver have a distinctive ring.

    There are westerns where you will hear this ring, I know I've heard it on a western but do not remember the title. It was very odd as I bought these more as a favor than for value and did not suspect the ring to be recognizable.

    This technique increases the usefulness of old, destined for the trash, motherboards as designing and etching a PCB for surface mounted devices is a bit of an investment in time. It also saves the landfill from getting as much toxic waste and garners the salvager a useful return on investment.
