一种基于门限RSA的容侵系统结构

An Intrusion Tolerant Architecture Based on Threshold RSA

指出了为保护大的服务器群组 ,继防火墙和入侵检测技术之后容侵技术已成为又一重要技术 .提出了一种容忍入侵的体系结构 ,对系统组件采用冗余和多样性技术相结合 ,利用门限秘密共享技术实现系统的可用性和关键数据的保密性 ,来达到容忍入侵的目的 .

For protecting the large server group, the technology of Intrusion Tolerant System has become another essential technique succeeding the firewall and IDS techniques. This paper proposes a framework model of ITS(Intrusion Tolerant System) .We utilize the techniques of both redundancy and diversity and threshold secret share schemes to implement the survivability of system and to protect confidential data from compromised service in the presence of intrusions.
