H.235-Recommendation of Security and Encryption for H-Series Multimedia Terminals
Liu Bao · Journal of Information Engineering University · 2002
In order to ensure the security of multimedia communication, H.235 recommendation,an important recommendation of Internet security, describes enhancements within the framework of the H.3xx Series recommendations to incorporate security services such as authentication and privacy (data encryption). The proposed scheme is applicable to both simple point to point and multipoint conferences for any terminals which utilize Recommendation H.245 as a control protocol. The paper describes the influence of Recommendation H.235 in the H.323 framework and the functions of H.235. H.235v2 supersedes H.235v1 featuring several improvements such as elliptic curve cryptography, security profiles, new security countermeasures (media anti spamming), support for the Advanced Encryption Algorithm,and support for backend service.
