Hybrid Obfuscation of Encryption

Abstract

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.
