PC platform trustworthiness evaluation based on Bayesian Network

Chain of Trust based on TPCM (Trusted Platform Control Module) is the core technical mechanism to ensure the trustworthiness of PC platform in China national trusted computing standards. The factors and their relations in PC platform that implements Chain of Trust based on TPCM are analyzed. Model of PC platform trustworthiness is established based on Bayesian Network. And two applications of the model in trustworthiness evaluation and factors detecting influencing trustworthiness are discussed.
