WebFeb 4, 2024 · Ephemeral Diffie-Hellman (DHE in the context of TLS) differs from the static Diffie-Hellman (DH) in the way that static Diffie-Hellman key exchanges always use the same Diffie-Hellman private keys. So, each time the same parties do a DH key exchange, they end up with the same shared secret. A cryptographic key is called ephemeral if it is generated for each execution of a key establishment process. In some cases ephemeral keys are used more than once, within a single session (e.g., in broadcast applications) where the sender generates only one ephemeral key pair per message and the private key is … See more Private (resp. public) ephemeral key agreement keys are the private (resp. public) keys of asymmetric key pairs that are used a single key establishment transaction to establish one or more keys (e.g., key wrapping … See more • Cryptographic key types • Session key See more • Recommendation for Key Management — Part 1: General, NIST Special Publication 800-57 • NIST Cryptographic Toolkit See more

WebEphemeral Diffie-Hellman (DHE) The key exchange must be ephemeral, meaning the server and client will generate a unique set of Diffie-Hellman parameters and use the keys just once per session. The exchange-related encryption is deleted from the server after the transaction ends, which ensures that any given session key is almost useless to hackers. WebPublic ephemeral key agreement keys are the public keys of asymmetric key pairs that are used in a single key establishment transaction to establish one or more keys (e.g., key wrapping keys, data encryption keys, or MAC keys) and, optionally, other keying material (e.g., Initialization Vectors).
