High-speed computational method for encrypted data

Achieving higher computational speed than conventional methods without decryption

Overview

This technology is a decryption-free processing method for encrypted data by probability arithmetic way. Conventional FHE (Fully Homomorphic Encryption) method is able to deal with encrypted data, however, the extremely time-consuming computation makes it problematic. This invention utilizes probability arithmetic way for unlimited times of additions and multiplications. Accordingly, the costing time for computation is much decreased compared with conventional methods.
