UTA WG @IETF 90, Toronto / TUESDAY, July 22, 2014 / 0900-1130  Morning Session I

Short summary

The three existing UTA drafts have a broad consensus on their technical content. Multiple participants promised to provide thorough editorial review (especially of the BCP draft) in the following two weeks. All comments and suggestions will be integrated in the next versions of the documents. The goal of the WG is to successfully complete final calls for all three IDs before Nov 2014. In parallel, (i.e., before IETF91) the WG will start focusing the “EMAIL protocols using TLS” topic. Contributions towards this topic, as well as additional (new) topics around using TLS with applications are mostly welcome on the list and/or towards IETF91.

A lot of interest from the community to collect more inputs and integrate them into a single IETF document to be used by wider audience. The work will continue on UTA, unless/until other possible venue becomes identified.

"Binding Security Tokens to TLS Channels" was presented by Andrei Popov
See meeting's materials at http://www.ietf.org/proceedings/90/slides/slides-90-uta-0.pdf
An introduction to a new mechanism, which is a part of a larger ecosystem. The authors are working on a more complete draft to be submitted soon and be socialized with broader IETF community.

Thanks,
Leif and Orit.
