Re: [Sframe] [Moq] FW: New Version Notification for draft-mattsson-cfrg-aes-gcm-sst-00.txt

This is interesting for SRTP as well, so I suggest adding the AVTCore mailing list.

Advanced Encryption Standard (AES) with Galois Counter Mode with Secure Short Tags (AES-GCM-SST) is very similar to AES-GCM but have short tags with forgery probabilities close to ideal. The changes to AES-GCM were suggested by Nyberg et al. in 2005 as a comment to NIST and are based on proven theoretical constructions.

Audio packets are small, numerous, and ephemeral, so on the one hand, they are very sensitive in percentage terms to crypto overhead, and on the other hand, forgery of individual packets is not a big concern.
