摘要
本文对入侵容忍的模型和TTCB结构进行了分析,在M AFTIA节点基础上,增加了一个事件处理引擎的核心模块,使得节点在参与者层与站点层支持自由选择安全群组通信系统中的密钥协商协议和新的加密算法。以改进的M AFTIA节点为基本单元,构建了基于可信实时计算基的新型安全群组系统。该系统能够集成新的安全群组通信密钥协商协议,通过事件处理引擎模块完成群组通信安全的任务,在安全性能方面更为灵活,具有较好的可扩展性与容忍入侵能力。
Secure group communication has been an active research area.In this paper, the intrusion tolerance model and TTCB architecture are analyzed. On the basis of MAFTIA node,an kernel model of event processing engine which support the node to select freely key agreement protocol and new encryption algorithms on the participant level and site level. The improved MAFTIA node has been regarded as a basic unit, a new architecture for secure group communication system based on TTCB. The system can integrate new key agreement protocols for secure group communication and implement the task of secure group communicaiton through the event processing engine. It is more flexible and better sacalabity and capabity of intrusion tolerance in the way of security.
