'''H.235''' covers [[security]] and [[encryption]] for [[H.323]] and other [[H.245]] based terminals.<ref>{{Cite web|url=https://www.itu.int/rec/T-REC-H.235|title=H.235 : Security and encryption for H-series (H.323 and other H.245-based) multimedia terminals|last=|first=|date=|website=www.itu.int|url-status=live|archive-url=https://web.archive.org/web/20131009123829/https://www.itu.int/rec/T-REC-H.235|archive-date=2013-10-09|access-date=2019-11-12}}</ref>

The standard addresses authentication by means of several [[algorithms]], including [[Diffie-Hellman]] methods, and privacy. Privacy allows for encryption, also of the [[Streaming media|media streams]].

The standardization board agreed on H.235.1 (former H.235 Annex D <ref>[http://www.itu.int/rec/T-REC-H.235.0-200509-I/en/ ITU-T Recommendation H.235.0] (09/05), Appendix IV, page 40</ref>) to be the minimum requirement of an H.235 conforming implementation.
H.235.1, also known as ''Baseline Security Profile'' defines [[Authentication]] and [[Integrity]].

An H.235.1 aware [[H.323 Gatekeeper]] can thereby assure that only trusted [[H.323#H.323_Architecture|H.323 endpoints]] are granted access to the Gatekeeper's services.
