Ephemeral key pair

Definition(s):

  A short-term key pair used with a public-key (asymmetric-key) algorithm that is generated when needed; the public key of an ephemeral key pair is not provided in a public key certificate, unlike static public keys which are often included in a certificate.

NIST SP 800-175B Rev. 1

  A key pair, consisting of a public key (i.e., an ephemeral public key) and a private key (i.e., an ephemeral private key) that is intended for a very short period of use. The key pair is ordinarily used in exactly one transaction of a cryptographic scheme; an exception to this is when the ephemeral key pair is used in multiple transactions for a key-transport broadcast. Contrast with a static key pair.
