An Efficient Trusted Chain Model for Real-Time Embedded Systems

Since the security problem of embedded systems are increasingly severe and the transfer of trusted chain is incomplete, a bottom-up and top-down transfer model of the trusted chain of embedded systems is presented in the paper, combining with the idea of trusted computing. Based on this model, the plan for booting trust, loading trust on real-time operating system and on applications with the prototype of partitioned RTOS on embedded system platform is designed, which can well solve to a certain extent the security problems that the current embedded system encountering.
