Definition Of

The security of software is threatened by piracy, tampering and reverse engineering. Attackers attempt to get important algorithms and sensitive data of software by static analysis or reverse engineering. Software protection becomes an important problem. The algorithm of code obfuscation based on class splitting is proposed that uses of obfuscation technology. The definition of class splitting and realization on algorithm are described. At the same time, the performance on algorithm is analyzed. The obfuscation method enhances the degree of complication about program and static analysis becomes more difficult. The algorithm is applicable to object-oriented program with class structure.

Software Watermarking

Over the past few decades ago, software developers analyzed robustly several forms of software protection against illegal copying or piracy. With the expansion in digital technology, the risk of illegal copying of software also amplifies. The increasing piracy rate has posed a serious threat to software developers leading to the development of various software protection techniques. However, various techniques have been proposed for copyright protection such as software watermarking, obfuscation, tamper-proofing and diversity. The code transformation (obfuscation) is a method of transforming a program into a form which is more complicated for an adversary to understand or change the original code from an illegitimate process of reverse engineering. None of the current code obfuscation approaches provide resistance from reverse engineering attacks. The reverse engineering threat occurs due to the unconfined software code to the user. Malicious reverse engineering of software codes can be harder by exertion of code transformation on software programs. To address this, we acquaint a peculiar code transformation approach for software protection. The proposed approach is used semantically equivalent to code clone within the source code to protect logical part of program text. We have successfully implement our approach using open source java project Gantt project system and open source java obfuscator's tools. In this paper, we present our approach and demonstrate it with an illustration. The intent of this method is to prevent static analysis attack and make dynamic attack compact for an adversary. This makes it worthwhile against reverse engineering attacks.

Source File

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.
