Abstract
An encoding method is disclosed. The present encoding method comprises the steps of: receiving a plurality of messages; encoding the plurality of messages into a polynomial expression having been multivariately defined, and encoding the multivariately defined polynomial expression so as to generate a homomorphic cyphertext.
Claims14
An encryption method comprising:
- receiving a plurality of messages;
- encoding the plurality of messages into a polynomial defined by multivariates;
- and
- encrypting the polynomial defined by the multivariates to generate a homomorphic ciphertext.

An operating device comprising:
- a memory configured to store at least one instruction and a plurality of predetermined prime number information;
- and
- a processor configured to execute the at least one instruction,
- wherein the processor encodes a plurality of messages into a polynomial defined by multivariates by executing the at least one instruction, and encrypts the polynomial defined by the multivariates to generate a homomorphic ciphertext.
