Research on How to Measure Trusted Computation Enabled Linux’s Critical Objects

These years saw rapid development of research on trusted computing.But research on trusted computing enabled Linux is not enough yet.Not every system critical object can be measured nowadays,which causes it is impossible to judge whether the system is trusted.To supply the gap,this paper represents a scheme to measure Linux’s system critical objects.This scheme based on the idea of Demetrios Lambrou and improved it.The problem that configuration files,dynamic shared library and executable scripts can not be measured has been fixed in this scheme.Now all components that maybe change system’s trusted state can be measured.
