Here's my key, your honor. I used a one-time pad to do the encryption. As you can plainly see, the encrypted file that the prosecution made such a big deal about contains nothing but some of my favorite verses from the King James Bible. You shouldn't infer anything from the fact that another key would make the file contain the evil stuff that was alleged (even though it is a bit strange that the last verse ends in the middle of a word).
Frank presents a cogent example of how the Staelin plan is a nonstarter. That is, it's a nonstarter *if* we remove any formal evidence of which crypto method is attached to a program. Cycles are cheap (compared to prison terms or a bullet in the head). Therefore, it's cheaper to let folks either make their own guesses at the crypto involved, or try several, than it is to unambigiously narrow down the searches to one particular algorithm, which the State can then insist on a decryption key for. Let the Staelin Plan be warning for us to prepare for an era in which the particular crypto method should not be revealed. (Cryptographically, any of the various algorithms are "polynomially equivalent," but, practically, the "King James Defense" used by Frank, brilliantly, will probably work. It's hard to argue with Scripture.) --Tim May Boycott "Big Brother Inside" software!
