Abstract
Disclosed herein are systems, methods, computer readable media and special purpose processors for obfuscating code. The method includes extracting an operation within program code, selecting a formula to perform the equivalent computation as the extracted operation, and replacing the extracted operation with the selected formula. The formula can be selected randomly or deterministically. The extracted operation can be an arithmetic operation or a Boolean operation.
