I said:
Their spokesagency, NIST, has said that it will be illegal to encrypt on top of Skipjack or to mung the LEEF.
Checking the relevant document again, I think this is wrong: -------------------- Federal Information Processing Standards Publication XX 1993 XX Announcing the Escrowed Encryption Standard (EES) [blah blah] The security equipment shall ensure that the LEAF is transmitted in such a manner that the LEAF and ciphertext may be decrypted with legal authorization. No additional encryption or modification of the LEAF is permitted. [...] -------------------- I remembered this text out of context. Correctly interpreted, it looks like it's just a specification for devices implementing the (voluntary, natch) Escrowed Encryption Standard. Sorry about that. Eli ebrandt@jarthur.claremont.edu
