Problems solved by technology

However, limited by the development of the WEB, the JavaScript script in the H5 of the web page is published on the front-end browser of the WEB application
It is easy for attackers to obtain and tamper with the code, which brings great security risks to the website, thereby compromising the privacy and interests of users
Therefore, the reinforcement technology to protect the security of the script code has become very important. Among them, the obfuscation technology transforms the original script code into a code that has the same function as it but is difficult to understand, which greatly increases the difficulty of the cracker.

Abstract

Embodiments of the invention provide a code file obfuscation method and device, electronic equipment and a storage medium. The method comprises the steps of determining an operator node and an operandnode according to a first syntax tree; creating a basic function file according to node contents corresponding to the operator node and the operand node; creating an agent function file according tothe node content corresponding to the operand node and the basic function file; and modifying the first syntax tree according to the proxy function file to obtain a second syntax tree, and obtaining an obfuscated code file according to the second syntax tree. The embodiment of the invention provides the code file obfuscation method, the electronic equipment and the storage medium. By recognizing the operator node and the operand node in the syntax tree, the execution functions of an operator and an operand are achieved through a basic function, an agent function is used for agenting the operator function, the operator function is mapped to the basic function, confusion of the operators and the operands can be achieved, and the reverse difficulty of code file cracking is increased.

Description

technical field [0001] The invention relates to the technical fields of machine learning and video analysis, in particular to a code file obfuscation method, device, electronic equipment and storage medium. Background technique [0002] With the vigorous development of Internet technology, WEB applications are favored by many users of mobile phones, PCs, and smart homes. However, limited by the development of the WEB, the JavaScript script in the web page H5 is published on the front-end browser of the WEB application. It is easy for attackers to obtain and tamper with the code, which brings a great security risk to the website and damages the privacy and interests of users. Therefore, the reinforcement technology to protect the security of the script code has become very important. Among them, the obfuscation technology transforms the original script code into a code that has the same function as it but is difficult to understand, which greatly increases the difficulty of ...
