The BIG-IP system supports all three Diffie-Hellman key exchange methods. They are: Diffie-Hellman Ephemeral (DHE) Diffie-Hellman Ephemeral uses temporary public keys. The authenticity of a temporary key can be verified by checking the digital signature included in the key exchange messages.

The letters “DHE” in a cipher suite name means that the Diffie Hellman Ephemeral mode is being used for key exchange. Contrast with plain or static “DH” (example DH_RSA_WITH_DES_CBC_SHA). Unsniff might support static DH because the diffie hellman parameters can be found in the server certificate.

Each instance or run of the protocol uses a different public key.
