AI Technical Summary

Problems solved by technology

At present, the code obfuscation technology mainly focuses on control flow obfuscation and data flow obfuscation. While these two obfuscation techniques increase the complexity and anti-attack capability of the program, they also increase the extra execution overhead of the program. This execution overhead sometimes even leads to program does not work properly

Abstract

The invention relates to the technical field of computers, and discloses a code obfuscation processing system and method for protecting a java program, and the system comprises a user login module which is used for providing a user login entrance and uploading the java program needing to be obfuscated; the information acquisition module is used for acquiring the uploaded java program to obtain a class file needing to be confused, and setting a confusion mode and a confusion level; the code obfuscation module is used for carrying out code obfuscation processing on the class file needing to be obfuscated by adopting a corresponding obfuscation mode and an obfuscation level; and the Class management module is used for managing the obfuscation result output by the code obfuscation module. The modules in the code obfuscation processing system are clear in division of labor, batch uploading obfuscation processing of the java programs can be achieved, the batch processing speed is greatly increased, the batch processing time is saved, additional execution expenses of the programs are not increased, and the effect of protecting the java programs is achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a code obfuscation processing system and method for protecting java programs. Background technique [0002] With the development of computer networks and distributed systems, java language has been widely used in the software industry due to its good platform independence and portability, so that developers can use java language to develop various s application. At present, java software has been widely used in various embedded applications, enterprise applications and other fields, providing new impetus for the rapid development of information technology. [0003] The compilation process of java programs is different from that of C / C++ programs. The object code generated by the C / C++ compiler is the code that runs on a specific platform. Through the lookup table, the compiler can convert all references to variables and method symbols into specific ones. memory offset. But t...
