Hi Sean, Joe, Eric and all,
I would like to address my thoughts/suggestions on 2 issues in option a. 1) The data limit should be addressed in term of blocks, not records. When the record size is not the full size, some user might not know what to do. When the record size is 1 block, the limit of 2^24.5 blocks (records) is way too low unnecessarily for the margin of 2^-60. In that case, 2^34.5 1-block records is the limit which still achieves the margin of 2^-60. 2) To achieve the margin of 2^-57 as the current text says, the limit number should be 2^36 blocks. Regards, Quynh. ________________________________ From: Cfrg <cfrg-boun...@irtf.org> on behalf of Sean Turner <s...@sn3rd.com> Sent: Friday, February 10, 2017 12:07 AM To: <tls@ietf.org> Cc: IRTF CFRG Subject: [Cfrg] Closing out tls1.3 "Limits on key usage" PRs (#765/#769) All, We’ve got two outstanding PRs that propose changes to draft-ietf-tls-tls13 Section 5.5 “Limits on Key Usage”. As it relates to rekeying, these limits have been discussed a couple of times and we need to resolve once and for all whether the TLS WG wants to: a) Close these two PRs and go with the existing text [0] b) Adopt PR#765 [1] c) Adopt PR#769 [2] Please indicate you preference to the TLS mailing list before Feb 17. Note that unless there’s clear consensus to change the text will remain as is (i.e., option a).
