Claim 0:
1. A method of operating a crypto processor, the method comprising:
encrypting input data to plural lattice-based texts;
multiplexing coefficients of polynomials of the plural lattice-based texts, to selectively provide the multiplexed coefficients to plural multipliers; and
generating a lattice-based text result for a homomorphic operation by operating the plural multipliers in parallel with respect to the multiplexed coefficients, including operating at least one first multiplier, of the plural multipliers, provided a first portion of the multiplexed coefficients, operating at least one second multiplier, of the plural multipliers, provided a second portion of the multiplexed coefficients, and selectively operating an adder provided some results of the operated plural multipliers.
