Masking Floating-Point Number Multiplication and Addition of Falcon
In this paper, we provide the first masking scheme for floating-point number multiplication and addition to defend against recent side-channel attacks on Falcon’s pre-image vector computation. Our approach involves a masked nonzero check gadget that securely identifies whether a shared value is zer...
