A new Request for Comments is now available in online RFC libraries. RFC 9528 Title: Ephemeral Diffie-Hellman Over COSE (EDHOC) Author: G. Selander, J. Preuß Mattsson, F. Palombini Status: Standards Track Stream: IETF Date: March 2024 Mailbox: goran.selander@ericsson.com, john.mattsson@ericsson.com, francesca.palombini@ericsson.com Pages: 82 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-lake-edhoc-23.txt URL: https://www.rfc-editor.org/info/rfc9528 DOI: 10.17487/RFC9528 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, forward secrecy, and identity protection. EDHOC is intended for usage in constrained scenarios, and a main use case is to establish an Object Security for Constrained RESTful Environments (OSCORE) security context. By reusing CBOR Object Signing and Encryption (COSE) for cryptography, Concise Binary Object Representation (CBOR) for encoding, and Constrained Application Protocol (CoAP) for transport, the additional code size can be kept very low. This document is a product of the Lightweight Authenticated Key Exchange Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol. Distribution of this memo is unlimited. This announcement is sent to the IETF-Announce and rfc-dist lists.
