      The impracticality of it comes simply from the fact that you have to store your pads somewhere.

      Assuming that we have a face to face meeting where agents can exchange any amount of information they need, in the one-time pad case maybe it is 6 months worth of pads on a disk (or a wad of papers, it really doesnt matter), in the other case its probably agreeing on an algorithm and a password/passphrase. Practicality is the size of the information that you need to protect. Lets also assume that information is mostly coming to you and not as much from you ('attack such and such at dawn', 'Abdul is an FBI spy do not trust him','meet with agent at such and such for explosives' ... ), lets also assume they are smart enough to keep communication at a minimum, thus they use no chatty "I'm still here" protocols.

      The FBI comes through the plumbing in your bathtub while you are having a bath. They search your house and soon enough they find your pads and know you're up to something. They now read all your mail/email etc and are able to read the information coming in. If you agreed to physical drops or some other ciphertext carrier your future communication would still be safe, however it would also be that in the other case so on that front it's a possible draw.

      Now had you chosen the algorithmic method they would find nothing even suggesting that you were engaged in secret communication since you can keep all of it in your head ("RC4", "thisisthetopsecretpassphrasethatihavetorememberto communicate"). You can't memorise 6 months of one-time pads, you have to store them somewhere.

      Benfeits come from the fact that there is less information to manage. The benefit of locking things in safes is that you dont have to carry all of it around, just the key.

      Imagine for example that you only thought the FBI was at the door and you already ate the 6 month supply of pads, now what do you do? You can't suddenly go to Afghanistan to meet at the cameldung fire again, what would you tell your boss at airport security? Unless you were hit by a car and suffered total long term memory loss you could still communicate if you were using an algorithm approach.

      As for relative security of various algorithms, lets take my favourite in this situation, RC4. It was invented in 1987 and has been around since, there are still (almost 15 years later) no published successful attacks against it (sure there might possibly be unpublished such but I doubt it). It is so incredibly simple you can not only memorise the algorithm with little trouble but if you really wanted to you could run it with pen and paper too. Now RC4 works with key sizes up to 256bits (256bit keys are, to quote Bruce Schneier, "[...] brute-force attacks against 256bit keys will be infeasible until computers are build from something else than matter and occupy something else than space"). This leaves us with attacks against the algorithm which is quite possible however, stream cipher analysis is comparatively straightforward and yet nothing has shown that it is vunerable. I would certainly think that your 6 month supply of pads is the easier target of the two.

No matter how many laws you pass, NOTHING will keep the BAD GUYS from being able to download this cryptographic software from European and other web sites.

    If Europe latches on to Senator Gregg's idea of mandating backdoors in all cryptographic products, then the people who want to use cryptographic products with no backdoors will simply write their own, or copy VERBATIM the computer source code for strong cryptographic software that already exists in many hundreds of published books.

    Allow me to quote Bruce Schneier, perhaps the United States' leading civilian cryptographic expert:

    "To illustrate the ease with which a cryptosystem can be implemented, I present the full code necessary for establishing a secure cryptographic channel over the internet, called the Diffie-Hellman Key Exchange. Both people communicating do the following:

    "1. Get public key (Y, P) of the other person. This is just a pair of large numbers.

    "2. Raise Y to the power of X, where X is the private key, modulo P. The result is the secret key.

    "Modular arithmetic is taught to fourth-graders under the name 'clock math,' and secret-key cryptosystems are just as easy to memorize and implement as public-key systems. I could teach any twelve-year-old how to reproduce from memory in under fifteen minutes a strong cryptosystem on any Windows machine. Any terrorist is quite capable of doing the same."

    This speaks volumes about the current state of cryptographic software in the world today, and the ease with which it can be implemented.

    If Senator Gregg's legislation is passed, it will have ZERO affect on the people who DO have things to hide from you, and will only harm the innocent citizens of the United States who wish nothing more than to insure that their banking records and private email conversations remain truly private.

This problem centers around the belief that it is easy to multiply two very large prime numbers, but given the product it is very difficult to go back to the original primes. I say belief deliberatly since it is possible (albeit extremely unlikely) that there is an easy way to factor large numbers. Most PGP implementations actually use Elgamal rather than RSA, but the principle is similar.

    No, it wouldn't, because of the way PGP encrypts messgages. Public-key crypto is slow, while many private-key algorithms are much faster. So, when encrypting a message, PGP creates a random key, and uses that key to encrypt the plaintext with a conventional, private-key cipher (CAST, IDEA, 3DES, Blowfifh, etc.).

    Then, once the message is encrypted, PGP encrypts that random key (the "session key") with the recipient('s|s') public key(s), using a public-key cipher like RSA. This allows you to encrypt a message for multiple recipients without needing a separate copy for each recipient (which would be required if the whole message were encrypted with a public-key cipher).

      Instead, cryptanalysts look for more subtle flaws in the encryption algorithm and attempt to exploit them to reduce the key search space.

      For instance, there is some evidence that the NSA knew about a type of cryptographic attack called differential cryptanalysis, many years before it became widely known. Back in the late 1970's when DES was being proposed, the NSA stepped in and made some modifications to the algorithm, but did not tell anyone why they were making these changes. The general assumption back then was that the NSA was trying to make the algorithm weaker in some way, although nobody could put their finger on exactly why.

      Fast forward nearly 10 years to the late 80's and cryptographers working in the open discovered differential cryptanalysis. Imagine their shock when they discovered that the original proposed DES algorithm was wide-open to attack by differential cryptanalysis, but that the modifications that the NSA introduced made DES much more resistant to this type of attack!

      So, for getting on for 10 years, and possibly considerably longer, the NSA had knowledge of how to blow holes in all kinds of different cryptographic systems (differential cryptanalysis has made several encryption algorithms that were previously widely-used obsolete) that were assumed to be secure, even by public researchers in the field.

      One-time pad encyption may indeed by entirely secure, but the requirement to distribute completely random keys that are each at least as long as the message you are sending, and which you cannot use twice, is just not practical for most people.

      Thus we use public-key and block cipher systems that MAY be flawed in some way. Researchers have gone over all these algorithms with a very fine toothcomb and have so far found nothing wrong with most of them, but that does not mean that people working for the NSA/GCHQ/whoever have not found these flaws. All we know is that no-one has made any useful attacks public.

      With all due respect to the excellent cryptography researchers working in academia and the commercial world, I believe that the government communications agencies are still some way ahead of them, and that this may amount to several years ahead. This is simply because they are generally better-funded than other cryptographers, and that they have many more years of research to draw on - cryptography has only been studied extensively outside of government and the military since the late 1960's or early 70's.

      Oh boy.

      government phone taps do not bother me because I know the only reason the .gov would want to tap my phones is if I were doing something bad

      That's a completely specious argument.

      Government people don't tap people's phones because they're doing something bad. Government people tap people's phones because they're under suspicion of doing something bad. You own a gun. You post on slashdot. You have a computer. You have political opinions. In some jurisdictions, that's more than enough to put you under suspicion of doing something bad. Like here in California.

      If the government knows someone is doing something bad, then they don't have any need of a phone tap: they already have enough evidence for a conviction. The rule in law enforcement is "go far enough to get sufficient evidence for a conviction, and then stop!" The perpetual fear in the DA's office is that law enforcement will uncover exculpatory evidence (that's evidence that proves the suspect's innocence). Since the prosecution is obligated under discovery rules to turn over all evidence to the defense, the presence of exculpatory evidence is a bad thing in the eyes of the DA's office. DAs don't make the connection with the fact that the presence of exculpatory evidence means they're prosecuting the wrong guy: they just want a conviction so they can close the book.

      What all this means is that if the LEAs have enough evidence to convict you, they won't even attempt to tap your phone, because their investigation might backfire. And since you don't need proof of wrongdoing to convict (you only need enough evidence to show wrongdoing "beyond a reasonable doubt"), the certain knowledge of wrongdoing is also a guarantee that the LEAs have enough evidence to satisfy a jury. Note that I said certain knowledge, not strong suspicion: LEAs are excitable folks who tend to leap to conclusions.

      And that tendency to leap to conclusions is part of the problem. By and large, LEAs are ignorant boobs. I've had a lot of contact with the Secret Service's technology investigations group and the FBI's computer crime squad in San Fransisco, and even these guys (law enforcement's technological elites) aren't sufficiently up to speed to avoid leaping to conclusions.

      Just look at the public records of the LAPD's illegal use of wiretaps throughout the 90's. At the instruction of the LA DA's office, no less. This was an ongoing, persistant misuse of wiretaps lasting many years, none of which were authorized by courts. With such widespread misuse in one jurisdiction, one must conclude that such misuse occurs in other jurisdictions as well. Cops, just like other professionals, have a tendancy to jump from one job to another, though perhaps not as often as in technical fields. So even if other jurisdictions didn't come up with the idea on their own, crosscontamination would've occurred. And the record is clear that illegal wiretaps have been commonplace throughout the US for decades at least. Since not all misuse is detectable, the truth must be that wiretaps are even more horribly misused than is known.

      What all this means is that you should assume that any ability that the .gov has will be misused to a greater or lesser degree. Innocent people will be hit by these misuses. Innocent people will go to jail as a direct result of these misuses. And innocent people will have no recourses.

      Whether you're talking about wiretaps, gun registration databases, sex offender registries, or crypto backdoors, the issue isn't whether or not you've done something bad. It's merely whether or not you appear to have done something bad, or in the worst case, whether or not it can be made to appear that you've done something bad.

      The simple matter is that with the sheer quantity and scope of the laws that already exist on the books, every one of you has done something bad. It's not possible to live a day in society without breaking a law. Do you have a bag of blue ice (the freezable cold packs) in your freezer? How about a piece of wood and some sandpaper? Or maybe a can of gasoline? If any of those are true, then you are in possession of bomb making materials. That's a federal felony. Do you own a car? Do you drive it? Then you're guilty of transporting hazardous materials without a license. Federal misdemeanor. Have you ever said the words "someone should kill the president" or anything to that effect, regardless of context or intent? Federal felony. Called a enemy in an online multiplayer game a "fucking nigger" for cheating? Or how about "bitch"? That's hate speech. Municipal misdemeanor in many jurisdictions. Do you possess pictures of your children as babies, naked? Child porn (go read the statute: it's very much over broad). Federal felony. Have you ever had sex with your boyfriend/girlfriend while they were a minor and you weren't (such as when you were 18 and they were 17)? Statutory rape. Federal felony with strong enforcement ("strong enforcement" is a term of art that means that the victim or victim's parents don't have to agree that a crime has been committed in order for prosecution to proceed).

      LEAs will try to tell you that they won't proceed with prosecution unless there was "intent to commit a crime." But in practice, that's nonsense. "Intent" is defined and shown by the DA's office (or AG's office), not by the LEAs or defendant, and in the case of strong enforcement statutes, is irrelevant anyway.

      Ok, I'm starting to ramble. So I'll sum up: we must always resist giving any power to law enforcement that is capable of being abused, because any abusable power will be abused, and the innocents are the only people who will suffer.

    The idea of *channel* encryption probably doesn't even cross their radar. But 'alienmole' is absolutely right: the most widespread and important use of encryption at the moment is *not* email; it is the use of ssh and friends to secure public channels. And the reason these are so important is obvious -- and probably much easier to explain to the public -- in these days of crackers and virus writers: you really don't want anyone to be able to break into your channel, and interfere with your remotely-controlled telescope or heart operation or hack into your corporate network or whatever.

    The case for SSH is much easier to make than the case for PGP, because of its demonstrable real-world importance. If we can move the debate towards channel security, away from email security, it will be much easier to win.
