摘要
针对提安全高群组通信系统的高效性,提出一种基于C/S模式的通用安全群组通信方案,该方案采用C/S通信模式,利用分布安全思想将安全技术无缝集成于群组通信中,通过在客户端加密,在服务器端进行密钥协商,在客户端与服务器端进行认证,在客户端的群组间进行访问控制。该方案支持组成员的动态加入或离开并支持每个组成员加入多个群组。与以前的安全群组通信相比,该方案在性能与安全性方面都有很大改善。
A general secure group communication scheme based on C/S model is developed to improve efficiency of most existing secure group communication systems. This scheme is presented based on C/S model. This scheme integrated security techniques into group communication by using distributed security idea. Encrypt is completed on client; key agreement is completed on servers; Authentication is completed on client and servers; access control is completed on groups in clients; this scheme support that dynamic join and leave of group member and also support that every group member join other group. Compared with previous group communication systems, it makes a great progress in security and efficiency.
