    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,
       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 size can be
       kept very low.
