Design and Implementation of a Parallel Recovery Trusted Startup Process Based on the Trusted Platform Module
一种并行可复原可信启动过程的设计与实现

For establishing the trustworthiness of the operating system,every program code of the operating system, which possibly reduces the trustworthiness,must be attest the integrality during the whole process form firstly switc- hing on power to finally establishing the running environment in the computer system.According to the standards of the trusted computing group,based on the analysis to the trusted startup process of the common operator system,a trusted boot process,called a Parallel Recovery Trusted Startup Process (PRTSP),which takes a parallel working be- tween CPU and TPM,and supports backup and recovery,has been put forward,and then designed and implemented by channel technology.Finally,we discuss the security and performance of the PRTSP.Based on the PRTSP,high as- surance of system security has been gained,thus the basis for building the trusted computing environment has been provided.
