Based on the complexity of space environment and the limitation of space resources, a dynamic metric authentication method for spaceborne operating system with the trusted chip support is proposed, and the configurable key metric object identification scheme and verification strategy are given. In this method, Key measurement objects and measurement strategies can be set according to the key level of on-board application. The critical application processes in operation can be measured and verified periodically, then a system security protection verification mechanism for on-board 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 on-board applications, which has great practical value.
Key words: on-board operating system / high assurance / dynamic measurement
