Power negative control terminal dynamic integrity verification method and system

Abstract

The application provides a power negative control terminal dynamic integrity verification method and system, wherein the method comprises the following steps: in response to receiving a target service instruction, a dynamic integrity measurement module determines target memory information which needs to be verified by dynamic integrity on the power negative control terminal based on the target service instruction; the dynamic integrity measurement module performs hash calculation on the target memory information to obtain first hash data; a hardware trusted root module acquires reference hash data corresponding to the target memory information which is stored in advance, and compares the reference hash data with the first hash data for consistency; when the consistency comparison result is consistent, a security policy execution engine sends an execution permission instruction to the power negative control terminal, so that the power negative control terminal executes the target service instruction. The power negative control terminal dynamic integrity verification method and system provided by the application significantly improves the overall security protection capability of the power negative control terminal in the actual operation stage.
