可信计算之细粒度模糊信任链研究

针对可信计算平台信任链技术的实现,在可信与安全相关性研究基础上,总结了信任链技术中存在的几个值得探讨的问题,对可信与安全的关系、认证链和信任链的区别以及组件划分的粒度等问题进行了分析。提出了一种细粒度模糊信任链模型,对组件划分原则、组件、系统的安全度量方法和信任转移理论进行了深入研究。为可信计算信任问题的研究提供了一个可行的方案,对实际系统可信性和安全性研究具有参考意义。

Research on Fine-grained Fuzzy Trust Chain of Trusted Computing

This paper focuses on the realization of the trust chain for trusted computing platform technolo-gy.On the basis of the research on correlation between trustand security ,it sums up several issues exist in the trust chain technology ,that are worth exploring ,and analyzes the relationship between trustand securi-ty,the differences between authentication chain and trust chain ,and the granularity of components divi-sion.This paper raises a fine-grained model of fuzzy trust chain ,and puts the study on principles of the components division ,component and system security measurement and trust transfer theory in depth .The paperprovides a feasible solution to the study on trust of trusted computing ,and has an important practical significance to the trust and securityresearch of actual system .
