摘　　要：近年来,随着远程教育的发展,远程教育的通信安全成为远程教育网络安全体系的研究热点。而构建于群组通信系统之上的安全群组通信系统(SGCS),不仅可提供可靠的、顺序的消息传送和小组成员关系服务,还能为成员间消息的传输提供安全机制。针对远程教育通信的特点,将SGCS和流媒体传输技术融合后应用于远程教育通信中,构建了一个远程流媒体课堂系统。In recent years,with the development of ELearning,the communication security of E-Learning has become a hot research to the network security field of E-Learning system.The security of group communication systems（SGCS） built on the group communication system,not only can provide reliable,ordered message delivery and services of group membership,but also provide security mechanisms for the message transmission among the members.In term of the characteristics of E-Learning,fused the technology of media streaming transmission and SGCS,and then the fusion was used in communication of E-Learning.Made a system of media streaming E-Class.
