Abstract

The invention relates to a software hybrid measure method based on trusted computing. The software hybrid measure method includes the steps: preprocessing software, analyzing and inserting program source codes, extracting behavior characteristics of the software, generating a software behavior characteristic library, embedding a software integrity measure strategy and generating an executable program to be measured; measuring the software, measuring integrity by a parallel optimization algorithm when starting the executable program to be measured according to the integrity measure strategy and the software behavior characteristic library, and dynamically measuring the executable program in real time in the running process. Static software measure and dynamic software measure can be simultaneously supported, software integrity measure and real-time dynamic behavior measure are combined by the aid of technologies such as parallel optimization, strategy embedding, inserting and system calling division, and the method has fine measure efficiency and low measure expenditure.

Description

technical field [0001] The invention relates to the field of trusted computing software measurement, in particular to a software mixed measurement method based on trusted computing. Background technique [0002] CG (Trust Computing Group, Trusted Computing Group) defines trustworthiness as: if an entity's behavior always achieves the expected goal in the expected way, it is called trustworthy. There are also scholars who believe that the credibility of software behavior refers to a statistics of whether the software is running as a subject, relying on its own functions to use, operate or act on the object, reflecting whether it violates regulations, exceeds authority, and exceeds the scope. characteristic. Currently, the main way to ensure software is trustworthy is to measure it. According to different measurement methods, software measurement methods can be divided into static measurement (that is, integrity measurement) and dynamic measurement. [0003] Static measurem...
