H .32 3系统主要用于局域网的多媒体通信 ,向网上的终端用户提供实时语音、数据和视频业务。随着它的商用市场的开拓 ,其中对网络安全的实施与保障受到越来越多的重视。在这种情况下 ,SG16工作组于 1998年 1月制定了H .2 35(用于H系列多媒体终端的安全与加密 ) ,并于 1999年 10月推出了适应新情况的H .2 35v2。H .32 3主要涉及了四个安全领域 :用户认证、数据加密、信息的完整性、不可否认性。它的研究重点为用户认证、数据加密和密钥管理。
H.332 The system is mainly used for multimedia communications over LANs to provide real-time voice, data and video services to end-users on the web. With the development of its commercial market, more and more attention has been paid to the implementation and guarantee of network security. In this context, the SG16 Working Group developed H. 235 (for the security and encryption of H Series multimedia terminals) in January 1998 and introduced H.22v2v2 in October 1999 to adapt to the new situation. H.332 There are four main areas of security involved: user authentication, data encryption, integrity of information, and non-repudiation. Its research focuses on user authentication, data encryption and key management.
