Claim 13:
14. An electronic device, comprising:
an encryptor configured to encrypt input data to plural lattice-based texts;
a memory configured to store coefficients of polynomials of the plural lattice-based texts for a polynomial multiplication; and
a crypto processor configured to:
multiplex the coefficients and transmit the multiplexed coefficients to plural multipliers; and
generate 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 operating an adder provided some results of the operated plural multipliers.
