Obfuscation is an encryption method. It allows the programmer to reform the code for protection. Obfuscation has promising chance to change the way of coding, where the programmer has the ability to program with any language, not necessarily English. Obfuscation, Unicode, and mathematical equations have the possibility to change strings and identifiers and to hide secret algorithms and business rules. Special dictionary is used for the string obfuscation to hide the logic of the program. The hybrid obfuscation technique will be implemented into a tool that automatically converts the code. It can be can be used for games and mobile applications for protection. With obfuscation, the application still has the ability to perform sufficiently and provide the desired output without any delays in performing timing. After obfuscating the source file, reverser still has the ability to break the object file but will not be able to read or understand and when obfuscation technique is complicated, reversing leads to error where original code disappears. In this chapter, hybrid obfuscation will be presented with examples, and obfuscation table is presented as well for future use.

“…In recent years, there has been much research on code obfuscation techniques (Ebad et al, 2021;Hosseinzadeh et al, 2018). The proposed methods use layout transformation (Collberg et al, 1997;Sebastian et al, 2016), data transformation and control transformation or a combination of these techniques. Authors of various algorithms use differently defined attributes to measure the quality of obfuscation.…”

One problem for manufacturers of IoT devices is protecting intellectual rights to the software. Unprotected software can easily be copied or analysed and used on other devices. Proving another party that the source code has been illegally copied is difficult. One of the solutions is code obfuscation, i.e., modifying the code, so it works the same way, but its structure is complicated to understand and analyse. The paper presents a solution dedicated to IoT devices that combines code obfuscation techniques and uses the trusted platform module to decrypt part of the data during execution. A dedicated obfuscation method is described. Experiments show that the method increases the time needed to change the code at least several times, and some junior programmers cannot understand an obfuscated code. Test results show almost no similarity between the code in clear form and obfuscated form. The obfuscated code is more complicated but takes slightly longer to execute.

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.
