Problems solved by technology

Due to the need of cross-platform, the intermediate program code contains a lot of source code information, so it is easy to be decompiled into source code
If a software development kit written in the above programming language is provided to a third party, the software development kit will likely be decompiled, thereby stealing key technologies and even allowing malicious users to attack the software development kit. The above situation can usually be achieved by obfuscating the program code in the software development kit, so that the software development kit becomes unreadable or difficult to understand, increasing the cost of attacking the software development kit
[0003] Usually, the process of obfuscating the program code in the software development kit is generally realized by manually writing the obfuscation rules. However, the above method of setting the obfuscation rules is prone to omissions and errors, and makes the obfuscation rules The generation efficiency is low, and some developers even obfuscate a small amount of program code in order to improve the generation efficiency of obfuscation rules and reduce trouble, which greatly increases the risk of program code leakage. Therefore, it is necessary to provide a A technical solution for generating more efficient obfuscation rules and reducing the risk of program code leakage

Abstract

The embodiment of this specification discloses a method, device, and equipment for generating data obfuscation rules. The method includes: obtaining target data in a software development kit that can be processed for data obfuscation, and obtaining the target data of the software development kit to be referenced. The non-application data referenced by the application; according to the target data and the non-application data referenced by the target application, determine the data to be confused in the software development kit; generate the software development tool based on the data to be confused Obfuscation rules for packages.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to a method, device and equipment for generating data confusion rules. Background technique [0002] Currently there are multiple programming languages, some of which are cross-platform languages, such as the Java programming language, etc., and the source codes written in the above programming languages ​​can be compiled into intermediate program codes. Due to the requirement of cross-platform, the intermediate program code contains a lot of source code information, so it is easy to be decompiled into source code. If a software development kit written in the above programming language is provided to a third party, the software development kit will likely be decompiled, thereby stealing key technologies and even allowing malicious users to attack the software development kit. The above situation can usually be achieved by obfuscating the program code in the software deve...
