Quantum-Resistant Cipher Suites for EDHOC

The Lightweight Authenticated Key Exchange (LAKE) protocol, Ephemeral Diffie-Hellman over COSE (EDHOC), achieves post-quantum security by adding new cipher suites with quantum-resistant algorithms, such as ML-DSA for digital signatures and ML-KEM for key exchange. This document specifies how EDHOC operates in a post-quantum setting using both signature-based and PSK-based authentication methods, and defines corresponding cipher suites.
