Analyzing the Chain of Trust Model Based on Entity Dependence

Ge Cheng, Hui Xie, Dongliang Zhang

Abstract: This paper provides a chain of trust model in line with the TCG trust concepts. This model gives a formal definition and proof of trust state, trust root and trust measurement and chain of trust by the concept of Smith’s entity dependence and the assumption that the authenticity can measure the entity’s conduct with accuracy. The model is universal, which can provide a theoretical basis for assessing the existing trusted computing platform, and provide theoretical support for the future research on how to build a more reasonable chain of trust.
