EFFICIENT LOW-OVERHEAD SIDE-CHANNEL PROTECTION FOR POLYNOMIAL MULTIPLICATION IN POST-QUANTUM ENCRYPTION

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 operation using the first input in a security mode determined by the control signal, the se...

Zusammenfassung:	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 operation using the first input 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, a second mode in which a shuffling-based side-channel protection is provided to the polynomial multiplication operation, a third mode in which a masking or splitting side-channel protection is provided to the polynomial multiplication operation, or a fourth mode in which a masking and shuffling based side-channel protection is provided to the polynomial multiplication operation. Other examples may be described.
