WebElliptic-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. 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 encrypt subsequent … WebDiffie-Hellman Security Suppose p is a prime of around 300 digits, and a and b at least 100 digits each. Discovering the shared secret given g, p, ga mod p and gb mod p would take longer than the lifetime of the universe, using the best known algorithm. This is called the discrete logarithm problem.
