Abstract

The invention provides a reliable PC trust chain test system based on the smallest test set and the system comprises a reliable platform module, a reliable measuring root core, a basic input and output system, a system starting loader and an operation system platform; the reliable platform module and the basic input and output system as hardware chips are arranged in the reliable PC trust chain test system; the system starting loader as a software module is built on the basic input and output system; the operation system platform as a software module is built on the system starting loader; the system starting loader is provided with the test system of the reliable measuring root core; the operation system platform is provided with a trust chain test antitype system, an event test system and a state test system. The reliable PC trust chain test system based on the smallest test set can carry out test to aim at the trust chains of different reliable PC platforms and can be used as the reference for the safety evaluation of the reliable PC.

Description

technical field [0001] The present invention relates to the technical field of computer information security, and mainly relates to a trusted PC following the specifications of the Trusted Computing Group (Trusted Computing Group, abbreviated as TCG, see reference [1]), and performing a specification consistency test on its trust chain. Background technique [0002] Trusted PC is a trusted computing platform that has been commercialized, and its main feature is that a trusted building block (TBB) is embedded on the motherboard. This TBB is the trust starting point of the trusted PC platform, which includes the Core Root of Trust for Measurement (abbreviated as CRTM) and the trusted platform module (Trusted Platform Module, abbreviated as TPM), as well as the communication between them and the motherboard. of the connection. TCG believes that a trusted computing platform must contain three roots of trust: Root of Trust for Measurement (abbreviated as RTM), Root of Trust for ...
