WebbAbstract: Shannon's information-theoretic approach to cryptography is reviewed and extended. It is shown that Shannon's random cipher model is conservative in that a randomly chosen cipher is essentially the worst possible. This is in contrast with error-correcting codes where a randomly chosen code is essentially the best possible.
