| Abstract: | Trusted computing ensures trustworthiness of a platform through extending the trust boundary from the root to the whole platform.Trusted measurement is invoked before the trust boundary is extended from one entity to including another.Static measurement,which takes place at startup,cannot ensure runtime trustworthiness,and therefore dynamic trusted measurement is indispensable to guarantee a computer platform to run dependably.According to dependability,availability and security of information and behavior,... |
