Security Model Research and Design of Embedded Trusted Terminal

The paper builds the trusted, bottom-up and flexible security framework of embedded system, by taking advantage of the TCM hardware security, using the self-developed embedded secure operating systems, basing on flexibility of embedded systems software and hardware, with studying of the dynamic trust chain model of DRTM and key security technology. The paper proposes a way to effectively prevent the information disclosure system security model, and takes a test environment to verify.
