The IESG has received a request from an individual submitter to consider the following document: - 'X.509v3 TLS Feature Extension' <draft-hallambaker-tlsfeature-09.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2015-05-05. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The purpose of the TLS feature extension is to prevent downgrade attacks that are not otherwise prevented by the TLS protocol. In particular, the TLS feature extension may be used to mandate support for revocation checking features in the TLS protocol such as OCSP stapling. Informing clients that an OCSP status response will always be stapled permits an immediate failure in the case that the response is not stapled. This in turn prevents a denial of service attack that might otherwise be possible. The file can be obtained via http://datatracker.ietf.org/doc/draft-hallambaker-tlsfeature/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-hallambaker-tlsfeature/ballot/ No IPR declarations have been submitted directly on this I-D. This draft has previously been (briefly) discussed on the TLS WG list but is not a working group item. The WG seemed fine with progressing an earlier version at that time.
