Abstract: A method of producing a white-box implementation of a cryptographic function, including: creating, by a processor, a white-box implementation of a cryptographic function using a network of two dimensional lookup tables; identifying two dimensional lookup tables using a common index; and rewriting the identified two dimensional lookup tables as a three dimensional table.
