A method of code obfuscation includes receiving a block of code. One or more obfuscation algorithms are then iteratively applied to the received code. The obfuscation algorithms are repeatedly applied, such that the output of the previous obfuscation algorithm provides the input to the next obfuscation algorithm. Each obfuscation algorithm may be a relatively simple code transform technique. The same obfuscation algorithm may be applied repeatedly or any combination of a plurality of obfuscation algorithms may be applied in any sequence. The cascading effects of applying rounds of obfuscation algorithms achieve obfuscated code exhibiting a significantly increased level of security that cannot be normally derived from the security of each individual algorithm.
