To those of you needing a break from your crypto studies:

The Alice and Bob After Dinner Speech

Against all odds, over a noisy telephone line, tapped by the tax authorities and the secret police, Alice will happily attempt, with someone she doesn't trust, whom she cannot hear clearly, and who is probably someone else, to fiddle her tax returns and to organize a coup d'etat, while at the same time minimizing the cost of the phone call.


A coding theorist is someone who doesn't think Alice is crazy.

There are three kinds of attack on an unintelligible cryptojoke according to the Jokeanalyst's resources. Firstly there is the Cipherjoke-only attack in which the Jokeanalyst is assumed to have unlimited amounts of material which is alleged to be funny.


Secondly and more powerfully there is the Known Plainjoke Attack in which he is given examples of jokes together with their explanations.


But most powerful of all is the Chosen Plainjoke Attack where he gets to ask the Cryptolaffer to explain WHY the joke is funny.
