Secure software components anti-reverse-engineering by table interleaving |
摘要 |
A method of securely implementing functions in a secure software application, including: determining, by a processor, two functions to be implemented by the secure software application; generating a first function lookup table; encrypting the first function lookup table; sorting the first function lookup table by encrypted operand; generating a second function lookup table; encrypting the second function lookup table; sorting the second function lookup table by encrypted operand; generating a flattened lookup table from a combination of the encrypted first and second function lookup tables; permutating the flattened table indices e.g. by use of public key cryptography encryption; and sorting the flattened table by the permutated flattened table indices. |
