| 摘 要： | 针对提高容忍入侵应用服务器群组通信动态安全性,提出了容忍入侵应用服务器组通信的认证与访问控制.在认证机制中,通过可信的服务器组对客户端的身份认证,有效阻止攻击者的伪群组的运行.在访问控制机制中,通过由所有组成员共同决定是否允许新成员的加入.在允许新成员加入群组后,相比于所有组成员协商组策略,通过发送组策略给新成员有效地降低了通信开销.

| Abstract: | Authentication and access control mechanisms of group communication is developed to improve dynamic security in intrusion tolerant server. In authentication mechanism, that identity of the client is authenticated by trusted server group can prevent attacker from implement of fake group. In access control mechanism, all group members determined whether to allow new member join the group. Compared with group policy agreed by all group members, the group policy being sent to new member can reduce communication cost after new member joining the group. |
