    Elliptic-curve Diffie–Hellman ( ECDH) is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. [1] [2] [3] This shared secret may be directly used as a key, or to derive another key. The key, or the derived key, can then be used to ...
