Nytro Posted May 3, 2014 Report Posted May 3, 2014 [h=1][TLS] Confirming Consensus on removing RSA key Transport from TLS 1.3[/h]The discussion on this list and others supports the consensus in IETF 89 to remove RSA key transport cipher suites from TLS 1.3. The Editor is requested to make the appropriate changes to the draft on github.More discussion is needed on both DH and ECDH are used going forward and on if standard DHE parameters will be specified.Joe[For the chairs]On Mar 26, 2014, at 11:43 AM, Joseph Salowey (jsalowey) <jsalowey at cisco.com> wrote:> TLS has had cipher suites based on RSA key transport (aka "static RSA", TLS_RSA_WITH_*) since the days of SSL 2.0. These cipher suites have several drawbacks including lack of PFS, pre-master secret contributed only by the client, and the general weakening of RSA over time. It would make the security analysis simpler to remove this option from TLS 1.3. RSA certificates would still be allowed, but the key establishment would be via DHE or ECDHE. The consensus in the room at IETF-89 was to remove RSA key transport from TLS 1.3. If you have concerns about this decision please respond on the TLS list by April 11, 2014.> > Thanks,> > Joe> [Speaking for the TLS chairs]> _______________________________________________> TLS mailing list> TLS at ietf.org> https://www.ietf.org/mailman/listinfo/tlsSursa: Re: [TLS] Confirming Consensus on removing RSA key Transport from TLS 1.3 Quote
