Cryptographic architecture with instruction masks and other techniques that interfere with differential power analysis |
| abstract |
An apparatus and method for preventing security leakage when a differential power analysis (DPA) attack is used in a smart card or the like. Randomization of access order to 8 SP boxes of DES encryption, and random number pseudo random instructions are inserted into SP box entry address calculation subroutine to input and output SP boxes The possibility of a successful DPA attack is reduced by modifying the timeline relationship.
