Abstract

Masked scalar blinding circuits for a side channel analysis (SCA) attack countermeasure are provided. A circuit can include logic gates configured to receive a private key and generate a first private key value and a second private key value that sum to the private key, a first multiplier configured to generate a first product based on a first random number and a multiplicative group order, a second multiplier configured to generate a second product based on a second random number and the multiplicative order group, and circuitry configured to generate a result and a carry out, based on the first private key value, second private key value, the first product, and the second product.
