Clave efímera

Dícese de las claves criptográficas de corta duración o que simplemente sólo se usan una vez.

(en) ephemeral

(I) /adjective/ Refers to a cryptographic key or other cryptographic parameter or data object that is short-lived, temporary, or used one time. (See: session key. Compare: static.) [RFC4949:2007]

(en) Ephemeral key

A cryptographic key that is generated for each execution of a key establishment process and that meets other requirements of the key type (e.g., unique to each message or session).

In some cases ephemeral keys are used more than once, within a single session (e.g., broadcast applications) where the sender generates only one ephemeral key pair per message and the private key is combined separately with each recipients public key.

[NIST-SP800-57:2007]
