*This abstract for appeared for patent application  number 18070846 Titled 'APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION OPERATION'

==Simplified Explanation==

This abstract describes an apparatus and method that use homomorphic encryption. The apparatus includes a processor and memory. The processor is configured to generate split polynomials from a ciphertext, which is a representation of a polynomial with a certain degree. The split polynomials have a lower degree than the original polynomial. The processor then performs element-wise operations on the split polynomials to generate partial operation results. Finally, the processor combines these partial operation results to generate a homomorphic encryption operation result corresponding to the original ciphertext.


==Original Abstract Submitted==

An apparatus and method with homomorphic encryption are included. An apparatus includes a processor configured to, and/or coupled with a memory storing instructions to configure the processor to: generate, from a ciphertext corresponding to a polynomial having a first degree for performing a homomorphic encryption operation, split polynomials having a second degree by factorizing the polynomial, wherein the split polynomials have a second degree that is less than the first degree, generate partial operation results by performing an element-wise operation using the split polynomials, and generate a homomorphic encryption operation result corresponding to the ciphertext by joining the partial operation results.
