Abstract: Power system is an important national infrastructure. Its safe and stable operation is the important guarantee of economic development and national security and stability. Chinas power system has been in safety protection with relevant regulations and requirements of the departments of the state, but the face of the current complex cyberspace security situation, there are still subject to APT and other malicious code attack risk. Trusted computing refers to the calculation of the operation at the same time security, so that the operation and process behavior under any conditions, the results are always the same as expected, the calculation can be measured throughout the control, not interference, is to change the traditional “Kill” the basis of passive defense technology. This paper analyzes the information security risks and challenges faced by the power system. and introduces the research and application of the trusted computing technology in the power system, and gives the recommended prospect for the engineering application of the trusted computing in combination with the actual production situation. Based on the trusted computing technology to build the power information security and immune system, and create an important industrial production control system and information infrastructure in the application of trusted computing technology to achieve high safety level protection of the precedent, the safety of other industries construction is also given worthy of reference and reference to the model.

Key words: electric power system, trusted computing, active defense, information security, advanced persistent threat (APT)
