Menezes-Qu-Vanstone (MQV) is an authenticated protocol for key agreement based on the Diffie-Hellman scheme.

Like other authenticated Diffie-Hellman schemes, MQV provides protection against an active attacker. The protocol can be modified to work in an arbitrary finite group, and, in particular, Elliptic Curve groups, where it is known as Elliptic Curve MQV (ECMQV).

Menezes-Qu-Vanstone is incorporated in the Public Key standard IEEE P1363 and NIST.SP.800-56A standard.

Some variants of MQV are claimed in patents assigned to Certicom.

Menezes-Qu-Vanstone has been dropped from the National Security Agency's Suite B set of cryptographic standards.
