Dear colleagues, Since there is a considerable interest to the question of increasing session keys lifetime (several productive off-the-list personal discussions about CryptoPro key meshing algorithms and http://eprint.iacr.org/2016/628 started after the Friday posting), maybe we should think about getting started a work on a document on efficient re-keying (about techniques without secret state and/or techniques with it (like in M. Abdalla and M. Bellare work, https://cseweb.ucsd.edu/~mihir/papers/rekey.html)) mechanisms for common cipher modes (CTR, CCM, GCM, CBC, CFB) in CFRG?
If you consider it reasonable, we can prepare a first version of such a draft based on our results (both included in that our preprint and new ones which we are working on currently) before IETF 97 to be able to have a discussion on this issue there in Seoul. Kindest regards, Stanislav Smyshlyaev
