  • Publication number: 20240313944
    Abstract: An apparatus and method with homomorphic encryption are provided. A method for performing a homomorphic encryption operation may include generating a second ciphertext, having a second total number of dimensions, by performing a key switching operation using a key-switching key to generate the second ciphertext, encrypted by a second secret key, based on a homomorphic encrypted first ciphertext on a first modulus encrypted by a first secret key, where the first ciphertext has a first total number of dimensions, and generating a ciphertext on a second modulus by performing a blind rotation operation based on the second ciphertext and an operation key.
