APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION OPERATION - A simplified explanation of the abstract
- This abstract for appeared for patent application number 18070846 Titled 'APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION OPERATION'
Simplified Explanation
The 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 obtain 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.
