Claim 18:
19. A method of operating a crypto processor, the method comprising:
encrypting input data to plural lattice-based texts;
selectively providing, to different multipliers of plural multipliers, coefficients of polynomials of the respective lattice-based texts for one homomorphic operation selected, based on a set operation mode, from among plural different homomorphic operations; and
generate a lattice-based result of the selected homomorphic operation by operating the plural multipliers in parallel with respect to the selectively provided coefficients, including operating at least one first multiplier, of the plural multipliers, provided a first portion of the selectively provided coefficients, operating at least one second multiplier, of the plural multipliers, provided a second portion of the selectively provided coefficients, and selectively operating an adder provided some results of the operated plural multipliers.
