Abstract
We’ve build a model of trust chain, and developed TCSE, a tool for estimating the security properties of the trust chain. The highlight of TCSE is that it can generate a probabilistic finite state automaton and verify or calculate four security properties of a trust chain following our algorithms. These properties are: credibility, usability, restorability and conformity. With these four values of a trust chain, we can estimate the security of a trusted computer (a computer with a trusted computing module). Using this tool, an ordinary user with the help of the Common Vulnerability Scoring System (CVSS) from which one can easily get the needed parameters can figure out these four properties quickly. This tool can be used in the area where the security of trusted computers are needed to be precisely quantized.
