The IESG has approved the following document: - 'Channel Bindings for TLS 1.3' (draft-ietf-kitten-tls-channel-bindings-for-tls13-16.txt) as Proposed Standard This document is the product of the Common Authentication Technology Next Generation Working Group. The IESG contact persons are Paul Wouters and Roman Danyliw. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-kitten-tls-channel-bindings-for-tls13/ Technical Summary This document defines a channel binding type, tls-exporter, that is compatible with TLS 1.3 in accordance with RFC 5056, On Channel Binding. It also updates default channel binding used by SCRAM-* and GS2-* families of SASL mechanism when they are used over TLS 1.3+. Working Group Summary This document was not particularly controversial in the KITTEN WG. The IETF Last Call prompted a significant amount of discussion when forwarded to the TLS WG list, resulting in this document no longer having an Updates: relationship with RFC 8446 and the addition of a section discussing the impact of using a TLS-Exporter value that does not change over the lifetime of the TLS connection when there are multiple distinct authentication protocols consuming the channel binding value. Document Quality A couple people indicated plans to implement. Jonathan Hoyland was the main reviewer to raise the topic of non-uniqueness when channel bindings are reused within a TLS connection. He has indicated that the new text resolves his concerns adequately. Personnel Alexey Melnikov is the document shepherd. Paul Wouters is the responsible AD.
