Array Based Java Source Code Obfuscation Using Classes with Restructured Arrays

TL;DR

This paper introduces a novel Java source code obfuscation method using classes with restructured arrays, employing array restructuring, index transformation, and constant hiding, implemented via the JDATATRANS tool.

Contribution

It presents the first tool for array restructuring obfuscation in Java source code, enhancing code security through class-based array obfuscation techniques.

Findings

Developed JDATATRANS tool for array restructuring obfuscation

First implementation of array restructuring in Java source code

Improved code security through obfuscation techniques

Abstract

Array restructuring operations obscure arrays. Our work aims on java source code obfuscation containing arrays. Our main proposal is Classes with restructured array members and obscured member methods for setting, getting array elements and to get the length of arrays. The class method definition codes are obscured through index transformation and constant hiding. The instantiated objects of these classes are used for source code writing. A tool named JDATATRANS is developed for generating classes and to the best of our knowledge this is the first tool available for array restructuring, on java source codes.
