The lightweight authenticated key exchange protocol Ephemeral
Diffie-Hellman Over COSE (EDHOC) can be run over the Constrained
Application Protocol (CoAP) and used by two peers to establish a
Security Context for the security protocol Object Security for
Constrained RESTful Environments (OSCORE). This document details this
use of the EDHOC protocol by specifying a number of additional and
optional mechanisms, including an optimization approach for combining
the execution of EDHOC with the first OSCORE transaction. This
combination reduces the number of round trips required to set up an
OSCORE Security Context and to complete an OSCORE transaction using
that Security Context.
This document is a product of the Constrained RESTful Environments Working
Group of the IETF.
This is now a Proposed Standard.
