Two AES ciphers

2000-04-08 19:30:49
For the past few months, there has been much talk of the likelihood that the AES process will come out with two ciphers, not one. This was talked about at the SAAG meeting in Adelaide, and folks from NIST said that this was indeed the current thinking.

RFC 2440 and the current 2440bis draft has algorithm IDs that say "Reserved for AES with 128-bit key" and so on. It might be wise to allocate another three and specify that the actual algorithms used for IDs 7, 8, and 9 (and probably 11, 12, and 13) will be defined by a future RFC.
