Latest Patents

Luo is associated with 1 patent: “Method and System for Reducing FFT Calculations in FHE Bootstrapping.” The invention separates ciphertext into a vector of samples, applies FFT operations to a sample vector and a bootstrap key, and calculates a phase vector of corresponding W(a) terms. It then performs two sets of pointwise multiplications and applies an inverse FFT to the accumulated result to obtain the bootstrapped ciphertext. The approach is designed to reduce the FFT calculations required in the process.
