| titleOfInvention | Multi-word multiplier circuit and method for preventing power analysis attack |
| abstract | The invention provides a multi-word multiplier circuit and a method for preventing power analysis attack. The multi-word multiplier circuit includes an interface and circuitry. The interface is used for receiving a first parameter X comprising one or more first words and a second parameter Y' comprising a plurality of second words. The second parameter comprises a masked version of the non-masked parameter Y, using the masked parameter A Y Masking to make Y' ═ Y + A Y . Circuitry for calculating the product of Z X Y by accumulating a plurality of sub-products, each of which is obtained by multiplying a first word of X by a second word of Y' and subtracting the partial product P X B from the intermediate provisional sum Y Is calculated corresponding to a third word, where B Y Is A Y The included mask word. |
