The standardization board agreed on H.235.1 (former H.235 Annex D
ITU-T Recommendation H.235.0
(09/05), Appendix IV, page 40) to be the minimum requirement of an H.235 conforming implementation.
H.235.1, also known as ''Baseline Security Profile'' defines Authentication
Authentication (from ''authentikos'', "real, genuine", from αὐθέντης ''authentes'', "author") is the act of proving an assertion, such as the identity of a computer system user. In contrast with identification, the act of indicat ...
