摘要
随着基于SIP视频会议系统的发展和应用,通信的安全保护机制也越来越重要。根据IETF SIPPING工作组提出的集中式会议模型,提出了一种基于SIP的视频会议系统。该系统针对SIP协议所固有的安全漏洞,设计了具有一定身份认证密钥协商及媒体流加解密功能的系统模型,在理论上该系统具有一定的安全保护机制。
With the development and application of SIP - based multimedia conference system, the safety mechanism of multimedia communication is more and more important. According to the model of concentration conference setted by the IETF SIPPING group,this paper advances a SIP - based multimedia conference system. In order to improve the safe weakness of SIP,this paper designs a system model with the function of dignity - identity, secret - consultion arid media - code - encode. From the view of theory,this systemhas a safety mechanism.
