Application research of trusted computing platform in electric power information system

Abstract

In recent years, the rapid development of trusted computing with active defense ideas to solve security problem of computer and network system, and trusted computing is believed to be the most likely fundamentally solve the security of computer system. This paper puts forward an application scheme of trusted computing platform being used in electric power information system. According to security requirements of electric power information system, it designs a method of constructing dynamic trust chain based on system management mode (SMM), and makes dynamic measurement to system program and key application, in order to ensure operating system environment integrity and trusty, effectively defenses against malicious code, make great efforts to enhance power information system security defense capabilities.
