Ephemeral Diffie-Hellman with RSA (DHE-RSA) - Medium

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. 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 communications using a symmetric-key cipher. It is a variant of the Diffie–Hellman protocol using elliptic-curve cryptography. WebDiffie-Hellman Standards []. There are a number of standards relevant to Diffie-Hellman key agreement. Some of the key ones are: PKCS 3 defines the basic algorithm and data …

It requires two Diffie-Hellman key pairs (generated using a secure random and the Diffie-Hellman key generation procedure). Either of these key pairs can be ephemeral (i.e. used once or just a few times) or static (persistent, part of a DH certificate). After the public keys are …
