Abstract
A non-modular multiplier, a method for non-modular multiplication and a computational device are provided. The non-modular multiplier includes an interface and circuitry. The interface is configured to receive n-bit integers A and B. The circuitry is configured to calculate a non-modular product (A*B) by performing a sequence of computations, and to randomize a pattern of an electrical power consumed by the multiplier when performing the sequence. The sequence includes: generating a random number w, determining moduli Mand Mthat depend on a number R=2, k equals a bit-length of Mand M, and on the random number w, and calculating a first modular product C=A*B % Mand a second modular product D=A*B % M, and producing and outputting the non-modular product (A*B) based on the first and second modular products.
