Embodiment Construction

[0023] The program behavior acquisition and structure analysis method based on stub instrumentation contains the following steps (such as figure 1 shown):

[0024] Step 1. Static analysis: Control flow analysis, data flow analysis and library function analysis are performed on the program, the functions of the program are analyzed, the scope of each function of the program is determined, the structure of the program is analyzed, and the initial insertion position of the program is determined. Perform the first pass of pile insertion;

[0025] Step 2. Program behavior extraction: Simulate the execution of the program after the first pass of stubbing, extract the program behavior during the running process of the library function according to the flag bit of the stub function, and store it in the behavior library;

[0026] Step 3. Program structure analysis: According to the structure division rules, the structural characteristics displayed during the running of the program are...

Abstract

The present invention relates to an instrumentation based program behavior acquisition and structural analysis method. The program behavior acquisition and structural analysis method comprises the following steps of: step 1. static analysis: performing control flow analysis, data flow analysis and library function analysis on a program, performing analysis on functions of the program, determining a scope of each function of the program, analyzing a structure of the program, determining an initial instrumentation position of the program, and performing a first-pass instrumentation; step 2. program behavior extraction: performing simulation execution on the program subjected to the first-pass instrumentation, extracting a program behavior in a library function running process according to a flag bit of a pile function, and storing the program behavior into a behavior library; and step 3. program behavior analysis: performing partitioning on structural characteristics shown in a program running process according to a structural partitioning rule, and performing a second-pass instrumentation, and finally performing compiling to obtain an executable file. The instrumentation based program behavior acquisition and structural analysis method provided by the present invention has an excellent software behavior acquisition ability and structural analysis ability.

Description

(1) Technical field: [0001] The invention relates to a program analysis method, in particular to a program behavior acquisition and structure analysis method based on stub insertion. (two), background technology: [0002] Software analysis is an analysis method that focuses on software characteristics. Analysis, in layman's terms, is the process of breaking down a complex object into smaller parts in some way to better understand that object. Analytical techniques have long been applied to the research of mathematics and logic, and have been gradually adopted by more disciplines (such as chemistry, physics, etc.) in modern times. As a newly developed subject, software is very natural to introduce analysis technology in the research process. Many activities in the current software life cycle (design, implementation, testing, deployment, maintenance, etc.) are inseparable from analysis techniques. However, most of the existing software behavior analysis techniques cannot ac...
