Key-agreement protocols

method of exchanging cryptographic keys

key agreement protocol involving two parties each with an elliptic-curve public-private key pair

protocol whereby two or more parties can agree on a key in such a way that both influence the outcome

early construction for a public-key cryptosystem, a protocol devised by Ralph Merkle

cryptographic protocol for identification

MQV (Menezes–Qu–Vanstone) 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).
