Abstract
An encoding method includes: 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. The plurality of messages may be multidimensionally packed by using multivariates, and thus, an operation may be performed with low complexity in the process of matrix multiplication for ciphertexts packed with the multivariates.
