Abstract:

This paper analyzed the reality of computing platform and the threats, aiming at the requirements of homemade and threat computing software and hardware platform, high security level, and security trusted, used secure hardware platform, secure kernel firmware, secure domain three level framework, put forward the high secure computing platform architecture based on multi-kernel and multi-domain security extended level by level. The architecture uses trust computing, security and virtualized technology, realizes embed trust root, combine several secure mechanisms, overcomes the limitations of original computing platform architecture, and promotes the safety of high secure computing platform comprehensively.

Key words: security extended level by level, high security, computing platform, architecture
