Abstract
A method and system of the device may include identifying, in an FHE program, key-switching operations occurring after a ModRaise operation. In addition, the device may include determining a first aggregated polynomial sum and a second aggregated polynomial sum; and configuring instructions for performing a MultSum operation based on the determined first aggregated polynomial sum and the second aggregated polynomial sum, the instructions are programmed to be executed during runtime, where the MultSum operation outputs two polynomials, each of which is an inner product between a single cyphertext polynomial and the first aggregated polynomial sum and a single cyphertext polynomial and the second aggregated polynomial sum, thereby reducing memory usage and computational overhead and enhancing key-switching efficiency.
