The application of trusted computing technology on baseboard management controller platform

Abstract

This paper researches the application of trusted computing technology on baseboard management controller(BMC) which is important firmware in server. As the trust root of system, BMC and trusted cryptography module(TCM) can measure the firmware of domestic BMC and basic input output system(BIOS) during the boot of server, and the complete trust chain is built finally. In order to communicate with TCM, the logic of the FPGA on the BMC board is designed. Besides, the trusted software is developed in U-Boot. The results show that when the trust chain is built, it can detect if the firmware has been maliciously tampered, so the security and trusted environment of the server is established.
