Abstract: The operating system (OS) is a system software that manages both the hardware and the software resources in a computer，thus its security is of significant importance. As a major component of the new generation security technology, trusted computing is applied to virtualization，cloud computing while merging into the OS development and forming a new trusted OS. This paper describes the application and trending of trusted computing，including trusted virtualization platform，trusted cloud，and solution scheme of industrial control system based on trusted computing. It specifically narrates the trusted OS，a hybrid of trusted computing nested into the OS，including its concept，architecture and key technologies related，the enhancement on the OS security，and the elevation of users’s experience.

Key words: operating system, trusted OS, trusted virtualization platform, trusted cloud, security-enhanced, architecture
