Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
We claim: 1. A method comprising: maintaining a table, the table mapping an operation to one or more equivalent formulas; identifying, via a processor, a plurality of operations within program code to generate a set of replaceable operations; selecting a respective formula from the table for each operation in the set of replaceable operations, the selecting based on an input level of complexity; and obfuscating the program code to make the program code more resistant to reve…
