Problems solved by technology

However, most SCA tools are mainly based on the feature file analysis of software projects to identify open source components, and the detection granularity is rough, and there are many errors; and as the scale of development software becomes larger and larger, manual comparison detection is performed at the code level Obviously even more unrealistic

Abstract

The embodiment of the invention provides a method and a system for realizing rapid open source component detection of a source code file. The method comprises the following steps: generating a first Simhash value according to a target source code file, and carrying out matching analysis on the first Simhash value and a second Simhash value in a fingerprint database to obtain a third Simhash value in the first Simhash value; and obtaining source code files (namely auxiliary source code files) of a source code library corresponding to all or part of the third Simhash values, and performing code comparison or NLP text similarity analysis on the target source code file according to the auxiliary source code files. Through quick matching analysis based on the Simhash algorithm, the open source component detection efficiency is undoubtedly and greatly improved by the scheme, and in order to make up for false alarms possibly caused by quick matching of the Simhash algorithm, correction is carried out at relatively low overhead through corresponding measures in the scheme, so that the accuracy of related homologous component detection is ensured.

Description

technical field [0001] The embodiments disclosed in this application mainly relate to the technical field of software component analysis (SCA) security testing, and more specifically, relate to a method and system for realizing rapid open source component detection of source code files. Background technique [0002] For software development entities, code reuse is undoubtedly an element that can have a significant impact on software development performance. Generally speaking, code reuse in a narrow sense often refers to refining repeated code into reusable code. For example, the specific form can be a method, a set of templates, or a framework, etc., so as to avoid repeated coding code as much as possible. , thereby improving the coding efficiency. However, with the open source of third-party libraries and components, code reuse in a broad sense also includes: introducing third-party open source libraries and open source components into the developed software project; amon...
