security certificate

A set of security relevant data which is protected by integrity and data origin authentication from an issuing security authority, and includes an indication of a time period of validity [10181-1]. Note: All certificates are deemed to be security certificates (see the relevant definitions in 7498-2).The term "security certificate" is adopted in order to avoid terminology conflicts with [X.509 | ISO 9594-8] (i.e. the directory authentication standard).
