The Elliptic-Curve Diffie–Hellman (ECDH) is an anonymous key agreement protocol that allows two parties, each having an elliptic-curve … WebThe ECDH protocol is a variant of the Diffie-Hellman protocol using elliptic curve cryptography. ECDH derives a shared secret value from a secret key owned by an Entity A and a public key owned by an Entity B, when the keys share the same elliptic curve domain parameters. Entity A can be either the initiator of a key-agreement transaction, or ...
