Abstract
A multi-word multiplier circuit includes an interface and circuitry. The interface is configured to receive a first parameter X including one or more first words, and a second parameter Y' including multiple second words. The second parameter includes a blinded version of a non-blinded parameter Y that is blinded using a blinding parameter Aso that Y′=Y+A. The circuitry is configured to calculate a product Z=X·Y by summing multiple sub-products, each of the sub-products is calculated by multiplying a first word of X by a second word of Y′, and subtracting from intermediate temporary sums of the sub-products respective third words of a partial product P=X·B, Bis a blinding word included in A.
