A Practical Solution to Trusted Computing Platform Testing

Trusted computing is a new generation technology of secure computing environment proposed by trusted computing group (TCG). Although many TC vendors claim that their products are compliant to TCG specifications, itpsilas very difficult to affirm it. Moreover, according to some government regulations on security, TC products shall require the official approval. Thus the testing and evaluation on TC products are necessary. Especially, there is no a prototype with full testing on whole TC products. Aiming at these issues, we proposed a testing prototype to make up for the gap between TCG specifications and product implementations. We introduced the automata theory as test mechanism to achieve TPM specification compliance test, validate chain of trust compliance by analyzing TCG-BIOS, and use reflection mechanism to test each layer of TSS. As a result, our test shows that some popular trusted PCs donpsilat meet the TCG specification includes TPM, TCG-BIOS and TSS.
