| description | An apparatus comprises an input register comprising an input polynomial, a processing datapath communicatively coupled to the input register comprising a plurality of compute nodes to perform a number theoretic transform (NTT) algorithm on the input polynomial to generate an output polynomial in NTT format. The plurality of compute nodes comprises at least a first butterfly circuit to perform a series of butterfly calculations on input data and a randomizing circuitry to randomize an order of the series of butterfly calculations. |
