DESIGN AND IMPLEMENTATION OF TPM SUP320

摘要

Security of computer in network is becoming more and more challengeable. The traditional way of applying a common smart card to application can not meet the requirement of high degree of security in critical systems. Trust Computing Group (TCG) drafts out specifications on trust computing platform, which have been acknowledged by specialists in this field. Following these specifications, we designed and implemented a chip named SUP320 with SOC technology. This paper gives the chip's hardware architecture, firmware modules and method for low power. Performance of SUP320 is tested in the end. We find that SUP320 is better than traditional smart cards in both security and efficiency.
