claves criptográficas de corta duración o que simplemente sólo se usan una vez.
(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]
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]
