Trusted program dynamic measurement method and device based on LSM framework

The invention discloses a trusted program dynamic measurement method and device based on an LSM framework, when a process is called during running, if the process does not exist in a dmadlist cache list, the called process does not need to be measured, and the called process runs safely. If yes, a target page address corresponding to the memory segment of the called process is obtained according to the page table of the called process, the Hash value of data in each linear memory area in the target page address space is calculated through the national cryptographic algorithm, the Hash values are summed, and the metric value of the called process is obtained. And comparing the metric value of the called process with the metric reference value, and if the metric value is the same as the metric reference value, continuing to run the called process. And if not, processing the called process according to the measurement mode. According to the method, the minimum influence on operation of the operating system is ge
