Abstract
Devices, systems, and methods for secure number theoretic transform (NTT) and inverse NTT (INTT) operations are provided. A circuit includes a memory configured to store polynomial coefficients, butterfly operator circuits coupled to receive the polynomial coefficients and generate, after iterations of operating on the polynomial coefficients, transformed coefficients as outputs, a first subset of the butterfly operator circuits situated in series with each other and in parallel with a second subset of the butterfly operator circuits, and a shuffle circuit coupled between the memory and the butterfly operator circuits, the shuffle circuit configured to change an order in which the polynomial coefficients are provided to the butterfly operator circuits.
