Protecting Java Code Via Code Obfuscation

The language Java was designed to be compiled into a platform independent bytecode format. Much of the information contained in the source code remains in the bytecode, thus decompilation is easy. We will examine how code obfuscation can help to protect Java bytecodes. The objective of our work is to develop and use obfuscation techniques that produce obfuscated bytecode that is very hard to reverse engineer while at the same time not significantly degrading performance.
