Abstract:
A method is provided for generating an output from an input according to a secret using a white-box implementation of a cryptographic function having a first operation, a second operation, and a third operation. The method applies the input to a first operation to generate a first intermediate result, applies the first intermediate result to a second operation to generate a second intermediate result, and applies the second intermediate result to a third operation to generate the output, wherein at least two of the first operation, the second operation, and the third operation is implemented by a plurality of interconnected logic elements, the interconnection of the plurality of logic elements being comprised of one of a non-algebraic interconnection of logic elements and an algebraic interconnection of logic elements having obfuscated boundaries between the at least one of the first operation, the second operation and the third operation.
