Abstract

A homomorphic processing unit (HPU) 200 may accelerate homomorphic processing operations governed by a homomorphic encryption scheme. The HPU may access encrypted operands from memory, wherein an encrypted operand represents an encryption of unencrypted data by the homomorphic encryption scheme, wherein the encrypted operand is represented by a set of ciphertext words. The HPU may include a controller 205 to access instructions for operations to be performed on encrypted operands and convert them into micro-instructions for operations to be performed on ciphertext words. The HPU may further comprise a register memory 209 and multiple execution units that may be invoked in parallel by executing micro-instructions. The execution units may include a load/store unit 207 for transferring ciphertext words, an arithmetic logic unit 210 for performing arithmetic operations, and at least one ciphertext transformation unit 211, 212 configured to modify ciphertext words in compliance with the homomorphic encryption scheme.
