Concerning about Trust of Platform Hardware

This paper investigates the hardware trust of a trusted computing platform. Initially, some prior researches are discussed. Based on these researches, we point out that hardware trust is the same important as the software trust in a trusted computing platform. Then, we introduce the notion of Hardware Integrity Measurement (HIM), which is similar to the software integrity measurement required by the Trusted Computing Group (TCG). Its purpose is to collect and measure integrity of the whole-platform hardware devices, and the HIM result can be used for the further reporting and attestation. Next, a protocol for hardware integrity measurement is discussed in detail. Finally, we conclude that trust of platform hardware is pretty important, and shares of research attentions are deserved.
