With the rapid development of smart grids, smart meters, as terminals of smart grids, are taking on increasingly important tasks. As the smart meter terminal's working environment is complex and diverse, and smart meters suffer from endless physical attacks and cyber attacks, so the integrity of smart meters is under threat. Aiming at addressing the problems above, a dynamic integrity measurement scheme for smart meters based on trusted computing is proposed in this paper. Based on the idea of software traces and embedding, this scheme extracts the software traces and embeds it in the file in the offline phase. The process monitor is introduced to monitor software behavior in real time, effectively solving the TOC-TOU attack problem. Practice shows that this scheme saves memory resources, has little impact on system performance and high application value.
