Abstract
The lightweight authenticated key exchange protocol Ephemeral Diffie- Hellman Over COSE (EDHOC) allows two peers to compute a shared secret session key. Once the session key is available, the two peers can use the EDHOC_Exporter interface, e.g., to derive keying material for an application protocol. This document defines an in-band approach that can be used by the two peers to agree about the lengths of the outputs produced with the EDHOC_Exporter interface. The defined approach relies on an EDHOC External Authorization Data (EAD) item that can be exchanged in the first two EDHOC messages of an EDHOC session.
