The existing trusted computing technology （TCT） is hard to satisfy the real time property of embedded operating system （EOS） direclly. Firstly, this paper put forward a new chain of trust based on integrity measurement certificate by reducing legend TCG＇s chain of trust. Secondly, this paper designed the embedded real-time trusted computing module and trusted software stack which had been reduced and optimized. The average execution time of commands on embedded real-lime trusted platform module saved 65. 81% execution time. The application...
