Abstract
Embodiments of the invention discloses a system and a method for determining a result of applying a function to signals including a first signal and a second signal, wherein the function is a polynomial function of the signals such that a monomial in the function includes the first signal having a power less than or equal to a first maximum power, and wherein the first signal is partitioned into a first subsignal and a second subsignal, comprising a processor for performing steps of the method, comprising the steps of acquiring a second signal and a second subsignal; acquiring a set of encrypted powers of the first subsignal, wherein the set of encrypted powers of the first subsignal includes homomorphically encrypted powers of the first subsignal; and determining an encrypted result of the function based on a second subsignal, the set of encrypted powers of the first subsignal, and the second signal.
