Example of diffie hellman key exchange
WebDiffie–Hellman offers secure key exchange only if sides are authenticated. For authentication, sides are using public/private key. So if side A knows the public key of the side B, then A can simply use that key to encrypt the message (or the new session key). ... For example TLS supports authentication based on a symmetric shared secret in a ...

The first such scheme is the ElGamal encryption. A more modern variant is the Integrated Encryption Scheme See more The used keys can either be ephemeral or static (long term) key, but could even be mixed, so called semi-static DH. These variants have different properties and hence different use … See more The protocol is considered secure against eavesdroppers if G and g are chosen properly. In particular, the order of the group G must be large, particularly if the same group is used for large amounts of traffic.
