  • APPARATUS AND METHOD WITH HOMOMORPHIC ENCRYPTION
    Publication number: 20240313945
    Abstract: A computing apparatus and method are provided. A homomorphic encryption operation method includes dividing a ciphertext having a first number of dimensions into a plurality of ciphertexts having a second number of dimensions, converting a secret key of each of the divided ciphertexts to a joint secret key by performing a key switching operation, generating new ciphertexts by applying the joint secret key to the divided ciphertexts, and performing a blind rotation operation based on the generated ciphertexts.

  • Method and apparatus for modulus refresh in homomorphic encryption
    Patent number: 11722290
    Abstract: Disclosed is a method and apparatus for modulus refresh, where the method for modulus refresh of a ciphertext in homomorphic encryption includes receiving a first ciphertext corresponding to a first modulus, generating a second ciphertext by performing a blind rotation on the first ciphertext, and generating a target ciphertext corresponding to a second modulus greater than the first modulus based on the first ciphertext and the second ciphertext.
