Claim 7:
8. The method of claim 7, wherein the pipeline is arranged in a plurality of stages comprising:
a first stage for transforming the NTT domain polynomial vector to the INTT domain;
a second stage for transforming the INTT the polynomial matrix to the NTT domain;
a third stage for multiplying the polynomial matrix in the NTT domain by the first Keyswitch matrix;
a fourth stage for transforming the first early-summation element and the summation vector from the NTT domain to the INTT domain;
a fifth stage for transforming the first subtraction-result vector from the INTT domain to the NTT domain; and
a sixth stage for multiplying the first subtraction-result vector in the NTT domain by the inverse moduli vector.
