Hi, We have submitted a new version of draft-selander-ace-cose-ecdhe to LAKE with the new name draft-selander-lake-edhoc-00 The changes from draft-selander-ace-cose-ecdhe-14 are: - We merged the static Diffie-Hellman branch and moved it to the main body of the document instead of an appendix. The benefits of using static Diffie-Hellman keys was recently pointed out by Karthik. We think static Diffie-Hellman keys are the best option for RPKs. - Added a sentence that EDHOC with symmetric authentication does not offer protection of the PSK identifier ID_PSK (as pointed out by Karthik). - Added an additional sentence on key compromise and passive attackers. New issues on GitHub: - I added Karthiks mail about static Diffie-Hellman keys to the existing issue of static Diffie-Hellman key - I created a new issue on PSK identifier protection with a link to Karthiks mail.

Name: draft-selander-lake-edhoc Revision: 00 Title: Ephemeral Diffie-Hellman Over COSE (EDHOC) Document date: 2019-11-04 Group: Individual Submission Pages: 74 URL: https://www.ietf.org/internet-drafts/draft-selander-lake-edhoc-00.txt Status: https://datatracker.ietf.org/doc/draft-selander-lake-edhoc/ Htmlized: https://tools.ietf.org/html/draft-selander-lake-edhoc-00 Htmlized: https://datatracker.ietf.org/doc/html/draft-selander-lake-edhoc Abstract: This document specifies Ephemeral Diffie-Hellman Over COSE (EDHOC), a very compact, and lightweight authenticated Diffie-Hellman key exchange with ephemeral keys. EDHOC provides mutual authentication, perfect forward secrecy, and identity protection. EDHOC is intended for usage in constrained scenarios and a main use case is to establish an OSCORE security context. By reusing COSE for cryptography, CBOR for encoding, and CoAP for transport, the additional code footprint can be kept very low. Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org. The IETF Secretariat
