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.
