Novel Obfuscation Algorithms for Software Security

Over the years, several software protection techniques have been developed to avoid global software piracy, which has increased over 40% and has caused $11 billion loss. Code Obfuscation is one of these techniques and it is very promising one. Code obfuscation is a form of software protection against unauthorized reverse-engineering. In this paper, we give information about available software obfuscation tool kits in the market, along with JHide and their comparison. We propose three new obfuscation techniques, based on composite functions, which are Array Index Transformation, Method Argument Transformation and Hiding Constants. In addition to that, we also propose a new obfuscation algorithm based on Discrete Logs to Pack the Words and another one, based on Affine Ciphers, to Encode String Literals. Finally, we conclude our paper identifying the need for reviewing the performance of the algorithms as the future scope of our work.
