Research on Trusted Computing Technology in Embedded Real-time Operation System
摘要
Abstract
The Trusted Computing Technology(TCT) is an effective way to solve Embedded Real-time Operation System(ERTOS) security. However, the existing TCT is hard to satisfy the properties of real-time and low power consumption directly. Based on VxWorks kernel, this paper puts forward a solution of trusted computing by designing embedded real-time trusted computing module and trusted software stack, which can realize the chain of trust by using integrity measurement certificate and establish the lightweight access control architecture. Experimental results show that the average execution time of commands on trusted platform module saves 65.81%execution time compared with SW-TPM module. Lightweight access control affects the kernel by increasing few execution overhead, which can meet the ERTOS requirements of real-time and low power consumption as a whole.关键词
