Re: Russia Intercepts US Military Communications?

One would expect that all US military communications, even trivial ones, are strongly encrypted, given the ease of doing this. Someone, more well informed, please reassure me that this is the case. Possibly someone was bribable - presumably the CoW need to share the same frequencies and keys, so - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
Re: AES-128 keys unique for fixed plaintext/ciphertext pair?
Hmm. another simpler theory to remove Shannon from the discussion. assume that the original assertion is correct - that for each plaintext p and each cyphertext c there exists only one key k that is valid to map encrypt(p,k)=c. In this case, for each possible cyphertext c, *every* possible plaintext p is a valid translation given a unique key k. for that reason, the uniary distance for encrypt() must be larger than one block - as it is self evidently not possible to map *any* c to a unique p without knowledge of the key. For that reason, Shannon cannot be applied to a single block of encrypt(), and can be safely ignored :) - The Cryptography Mailing List Unsubscribe by sending unsubscribe cryptography to [EMAIL PROTECTED]
