“…A determined attacker, after spending enough time to inspect obfuscated code, might locate the functionality to alter the functions and succeed. The renaming obfuscation, layout obfuscation, and source code obfuscation can be attacked by the reversing tools that are able to perform analysis to create a new name for the identifiers that are used in the source file [8].…”

In this research, a new Hybrid Obfuscation Technique was proposed to prevent prohibited Reverse Engineering. The proposed hybrid technique contains three approaches; first approach is string encryption. The string encryption is about adding a mathematical equation with arrays and loops to the strings in the code to hide the meaning. Second approach is renaming system keywords to Unicode to increase the difficulty and complexity of the code. Third approach is transforming identifiers to junk code to hide the meaning and increase the complexity of the code. An experiment was conducted to evaluate the proposed Hybrid Obfuscation Technique. The experiment contains two phases; the first phase was conducting reverse engineering against java applications that do not use any protection to determine the ability of reversing tools to read the compiled code. The second phase was conducting reverse engineering against the proposed technique to evaluate the effectiveness of it. The experiment of the hybrid obfuscation technique was to test output correctness, syntax, reversed code errors, flow test, identifiers names test, methods, and classes correctness test. With these parameters, it was possible to determine the ability of the proposed technique to defend the attack. The experiment has presented good and promising results, where it was nearly impossible for the reversing tool to read the obfuscated code. Even the revealed code did not perform as well as original and obfuscated code.

Reverse Engineering is the process of revealing hidden code from class file. It converts garbage to readable English text. The main purpose of Reverse Engineering is to uncover the hidden code when the documentation is poor, missing source file, and developer is no longer available to provide the original code source file. Hacker uses Reverse Engineering to attack the class file to uncover the code. Then, the code can be reused for other purposes without taking any permission from the original author. The class file contains all the information and business rules that will be revealed once Reverse Engineering process attacks. Anti-Reverse Engineering techniques are developed to stop, delay, and prevent Reverse Engineering; one of the most common techniques is Obfuscation. It has many forms of protection such as, changing the names of classes and variables names, hide classes, and change form of code. In this paper, an appraisal will be conducted to study the current Obfuscation techniques. This research proposes a new hybrid technique that is based on obfuscation; the technique will be using mathematics, Unicode, and unknown language to convert the source file to a garbage running file that does same task which normal source file does for java applications.
