You might be able to convince me that we should >include Phase 1 and Phase 2 in the first version if the charter. Remember that this effort is intended to be done in an IETF Working Group, and WGs are inherently open to all participants. If we begin the work or deciding the criteria that make a good hash without the experts from the international crypto community who understand those criteria being on-board, the WG will probably tend towards non-experts quoting (and misquoting) what they read in the trade press. There is the additional factor that we are just finding out some important things about hashes, and have heard very few analyses of that new information. Do the discoveries by Wang et. al. only apply to collisions? If we wait a year or two, will the crypto community be able to extend those into measurable preimage attacks? If so, what will we know then? I'm not saying we need to wait on chartering phase 2, but we should certainly not try to rush this based on our limited information. --Paul Hoffman, Director --VPN Consortium _______________________________________________ Hash mailing list Hash@lists.ietf.org https://www1.ietf.org/mailman/listinfo/hash
