Abstract
With the development of science and technology, embedded system plays an indispensable part in our daily life. Real time operating system (RTOS) is the critical part of it. To meet the stringent response time requirements, Xenomai is developed as a software framework adding real-time capabilities to the mainline linux kernel. And on the hand, the security of RTOS is a rising issue for computer industrial development, as RTOS used to be considered safer than other system. Therefore, trusted platform module (TPM) is proposed to ensure security form a hardware perspective. In this work, we built a trusted real-time platform based on dual kernel architecture. It comprises host OS and guest OS, which are implemented by trusted virtualization platform (TVP) and Xenomai respectively. In the platform, TVP was based on SW-TPM. Then some tests were carried out to verify performance of system that we built. The result shows that compared with original linux kernel, the average rate of time saving by our platform is 49.52%. The TPM commands executed in the present system is faster than that runs as binary file in the SW-TPM alone.
