Abstract

TCM (Trusted Cryptography Module) is the core of national trusted computing technology. This paper proposes the extending method of TCM in the embedded system, which is implemented on ARM embedded platform. After hardware architecture of trusted computing PC platform that is defined by TCG is researched and universal external interface of embedded platform is analyzed, SPI bus is selected to extend the signal, and special LPC bus cycle is implemented based on FPGA, which addresses the hardware extension issue of TCM in the embedded platform efficiently.
