Aucsmith-Like Obfuscation of Java Bytecode

This paper describes a functional dynamic Java byte code obfuscator based on the general ideas introduced by Aucsmith's algorithm. This tool provides a very high level of security for the obfuscated code due to the fact that the code that gets executed is not visible at all in the initial jar file, but at the cost of an extreme performance overhead. However, further improvements promise to drastically improve the performance of the obfuscated application.
