Embodiment Construction

[0076] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0077] The source code obfuscation method provided by the embodiment of the present application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 101 communicates with the server 102 through a network. The terminal 101 can send the source code to be processed to the server 102 . The server 102 can acquire the abstract syntax tree AST corresponding to the source code to be processed. For each AST node in the AST, the server 102 can determine the obfuscation processing strategy corresponding to the AST node according to the nod...

Abstract

This application relates to a source code obfuscation method and device. The method includes: obtaining the abstract syntax tree AST corresponding to the source code to be processed; for each AST node in the AST, according to the node type corresponding to the AST node, determining the obfuscation processing strategy corresponding to the AST node, and based on the The obfuscation processing strategy corresponding to the AST node obfuscates the AST node to obtain an obfuscated AST; performs code restoration processing on the obfuscated AST to obtain an obfuscated source code. By adopting the application, the source code can be obfuscated, so as to realize the protection of the source code.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a source code obfuscation method and device. Background technique [0002] At present, Internet technology is developing rapidly, and Internet reference technologies on PC and mobile terminals are increasing exponentially. At the same time, it has brought about the leakage of key technical codes. For most front-end codes, the JavaScript code is directly interpreted and executed by the browser, and can be directly viewed through the browser's development tools, making the JavaScript code very easy to leak, and easy to be stolen and tampered with. Therefore, there is an urgent need for a source code obfuscation method. [0003] Abstract Syntax Tree (AST) is an abstract representation of source code syntax structure. It represents the grammatical structure of the programming language in the form of a tree, and each node on the tree represents a structure in the source ...
