Research on Measurement Certification Technology for Trusted Computing of On-board Operating system

Based on the complexity of space environment and the limitation of space resources, a dynamic measurement authentication method for spaceborne operating system with the trusted chip support is proposed, and the configurable key measurement object identification scheme and verification strategy are given. In this method, Key measurement objects and measurement strategies can be set according to the level of spaceborne application. The critical application processes in operation can be measured and verified periodically, then a system security protection verification mechanism for spaceborne software is obtained. The experimental results show that the dynamic measurement method improves the reliability of the system, and the performance meets the requirements of spaceborne applications, which has great practical value.
