摘要： 入侵容忍技术是继信息保护技术和入侵检测、容错技术之后的第三代网络安全的核心。当受保护系统的组件受到攻击时,入侵容忍技术能维持整个系统关键信息和服务的完整性、机密性和可用性。该文介绍了入侵容忍技术的基本理论基础---拜占庭协议,在此基础之上,提出了一个入侵容忍系统的应用模型,并对其实现。

Abstract: Intrusion tolerant technology is the core of the third generation of network security in back of information protection,intrusion detection and fault tolerance technology . When the component of the protected system is attacked ,intrusion tolerant technology can maintain integrity ,confidentiality and usability of the whole system's key information and service . The paper introduces the basic theory of intrusion tolerant system——Byzantine protocol. On the basis of Byzantine protocol,the paper presents an applied module of intrusion tolerant system,and introduces each sub module .
