摘要
针对关键领域对系统的安全性、可靠性要求极高的特点,设计一种高可信容错计算机系统,将高可信与高可靠技术进行有机融合。采用高可信计算技术,以TCM构建可信密码支撑体系,实现平台自身的完整性、身份可信性和数据安全性。运用冗余容错技术,保证系统在有错误被激活的情况下依然能够提供不间断的服务。该系统通过原理实验样机测试,验证了该技术方案和实现途径的有效性。
Aiming at the requirement that security and reliability is very high,this paper designs a high-confidence fault-tolerant computer system to combine trusted computing and high-reliability technology.Depending on technology of trusted computing,password support system is constructed based on TCM to achieve platform integrity,identity authentication and data security.Depending on fault-tolerant technology,system provides uninterruptable service in an error case.The prototype system is tested by experiment,and technical program is verified to be effective.
