Technical Summary This document adds Elliptic Curve Cryptography (ECC) cipher suites to TLS 1.0-1.2. These cipher suites have some technical advantages over the currently defined RSA and DH/DSS cipher suites in terms of key size and performance. This document does not entail any changes to the TLS base specification. Note that Appendix B lists the changes from RFC 4492. Working Group Summary The WG was able to achieve consensus on advancing this document to Proposed Standard. Moving RFC 4492 to Standards Track was the main reason for the draft. It seemed odd to specify MTI algorithms based on ECC in TLS1.3 and have the TLS1.0-1.2 RFC for the same algorithms be Informational. Note that we needed to consult the CFRG on the "use of contexts". Our thanks to them for contributing to this work. Document Quality This is a bis draft so the majority of the draft has been reviewed by the IETF already. The -00 version of the individual draft allows easy diff to what was published as RFC 4492. Note that more was taken out than put in. Personnel Sean Turner is the Document Shepherd. Kathleen Moriarty is the responsible AD.
