基于模型检测的可信软件栈测试

Test of Trusted Software Stack Based on Model Checking

基于模型检测理论,提出了一种可信软件栈的测试方法,使用计算树逻辑对可信软件栈的函数调用进行抽象描述,通过验证可信软件栈函数的接口和函数调用是否符合规范,从而确定平台中可信软件栈的正确性.测试结果表明,一些可信计算平台产品中的软件栈不完全符合可信计算组织(TCG)的规范要求.

This paper presents a test method on TSS by model checking,and takes computation tree logics to formalize the function call of TSS,our aim is to confirm that the function call of TSS can successfully discriminate a trusted sequence from an insecure one.As a result,our test shows that the TSS on some trusted computing platforms incompletely meet the specification of trusted computing group.
