Abstract

The invention provides a program comparison method and system. The method comprises the following steps: respectively establishing a target function call graph corresponding to a target program and ato-be-compared function call graph corresponding to a to-be-compared program; obtaining a target anchor point in the target function call graph and a to-be-compared anchor point in the to-be-comparedfunction call graph; obtaining a target edge corresponding to the target anchor point and a to-be-compared edge corresponding to the to-be-compared anchor point, taking the function node at the otherend of the target edge as the target anchor point again, taking the function node at the other end of the to-be-compared edge as the to-be-compared anchor point again, and repeating the process untilall alignment anchor points are obtained; and judging whether the target program and the to-be-compared program have the same execution logic or not according to all alignment anchor points in the target function call graph and the to-be-compared function call graph. According to the method and system, the embedded representation is carried out on the edges in the sub-graphs by adopting the function call graph of the program and the neural network technology, so that the automatic comparison of the program is achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a program comparison method and system. Background technique [0002] Binary program analysis, also known as binary program reverse engineering (Reverse Engineering), is a technology designed to extract high-level semantic information from the original executable program. Software reverse engineering plays a very important role in many fields: in threat intelligence systems, reverse engineering is needed to analyze the opponent's tools; in black box testing, reverse engineering is needed to discover software vulnerabilities; in software copyright protection, reverse engineering is needed Perform software composition analysis, etc. [0003] The core of reverse engineering is to condense the program executed by the machine into computer behavior and function that can be described by human words. Since an executable program is a strong logical execution process for computers to ...
