The Secure Boot of Embedded System Based on Mobile Trusted Module

In this paper the transitive trust of TPM and the secure boot of MTM are analyzed. A scheme of secure boot for embedded system is proposed. Based on U-Boot and embedded Linux, the secure boot functions for embedded system are implemented by the integrity measurement, integrity storage and integrity reporting. This scheme can improve the security of embedded system by introducing MTM. Finally the implementation of secure boot is tested, which verify the effectiveness of the secure boot scheme.
