摘要： Embodiments are directed to low circuit depth homomorphic encryption evaluations. An embodiment of an apparatus includes a hardware accelerator to receive a ciphertext generated by homomorphic encryption (HE) for evaluation, determine two coefficients of the ciphertext for HE evaluation, input the two coefficients as a first operand and a second operand to a pipeline multiplier for low circuit depth HE evaluation, perform combinatorial multiplication between the first operand and portions of the second operand, accumulate results of the combinatorial multiplication at each stage of the pipeline multiplier, and perform reduction with Mersenne prime modulus on a resulting accumulated output of the combinatorial multipliers of the pipeline multiplier.

摘要： Embodiments are directed to homomorphic encryption for machine learning and neural networks using high-throughput Chinese remainder theorem (CRT) evaluation. An embodiment of an apparatus includes a hardware accelerator to receive a ciphertext generated by homomorphic encryption (HE) for evaluation, decompose coefficients of the ciphertext into a set of decomposed coefficients, multiply the decomposed coefficients using a set of smaller modulus determined based on a larger modulus, and convert results of the multiplying back to an original form corresponding to the larger modulus.
