Research of Reliable Trusted Boot in Embedded Systems

Since embedded systems have been widely used and integrated into almost all the electronic systems, the security and reliability of embedded system must not be ignored. In order to improve the security and reliability of embedded system, a feasible way is to establish root of trust and trusted boot to ensure the integrity and security of the system. This paper proposes Reliable Trusted Boot to provide a reliable and tamper-resistant embedded system. Our method adds extended trusted platform module and backup-recovery mechanism to traditional embedded system, controls the start sequence of platform's components, enforces trusted boot and recovers the system when necessary. Our implementation demonstrates the feasibility of Reliable Trusted Boot, it enhance the security and reliability of embedded system.
