WebSep 20, 2024 · Elliptic Curve Diffie-Hellman (ECDH) is a version of the Diffie-Hellman key exchange algorithm for elliptic curves, that determines how two communication participants A and B, can generate key pairs and exchange their public keys via insecure channels. The algorithm determines only how key pairs are generated, and the user defines the relation ... WebECDH 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.
