This document extends RFC 4279 and RFC 4785 and specifies a set of ciphersuites that use an Elliptic Curve Diffie-Hellman exchange authenticated with a pre-shared key. These ciphersuites provide Perfect Forward Secrecy. It also specifies one authentication-only ciphersuites (with no encryption). This ciphersuite is useful when authentication and integrity protection is desired, but confidentiality is not needed or not permitted.
