LIGHTWEIGHT SIDE-CHANNEL PROTECTION FOR POLYNOMIAL MULTIPLICATION IN POST-QUANTUM SIGNATURES

LIGHTWEIGHT SIDE-CHANNEL PROTECTION FOR POLYNOMIAL MULTIPLICATION IN POST-QUANTUM SIGNATURES

In one example an apparatus comprises a first input node to receive a first input, a second input node to receive a control signal, a polynomial multiplication circuitry to perform a polynomial multiplication function using the first input as an element of a digital signature protocol, the polynomia...

description In one example an apparatus comprises a first input node to receive a first input, a second input node to receive a control signal, a polynomial multiplication circuitry to perform a polynomial multiplication function using the first input as an element of a digital signature protocol, the polynomial multiplication function comprising a plurality of polynomial multiplication operations, the polynomial multiplication function performed in a security mode determined by the control signal, the security mode comprising one of a first mode in which no side-channel protection is provided to the polynomial multiplication operation or a second mode in which a shuffling-based side-channel protection is provided to the polynomial multiplication operation. Other examples may be described.
