【摘要】 在信息社会软件系统正在发挥着越来越重要的作用,对其可信性方面的要求也越来越高。文章在基于构件的可信软件框架基础上,对软件系统可信启动和完整性度量进行分析。根据在可信系统运行中对可执行构件进行完整性度量的方式不同,得到不同的构件信任链模型——链式信任链模型、星形信任链模型、加入失效链后的信任链模型。最后,文章基于信任链来对系统中构件之间的可信性进行分析与度量。更多还原

【Abstract】 With the software system playing more and more important role in the information society, the credibility of the software system is becoming more and more important. On the basis of component-based trusted software framework, this paper analyze the trusted startup and integrity measurement of the software system. According to the different ways of integrity measurement to trusted system, the different trust chain models —the chain-linked trust chain model, the star trust chain model and the trust chain model adding failure chain—are obtained. Finally, the credibility of the components in the system based on the trust chain is analyzed and measured.更多还原
