| titleOfInvention | Homomorphic encryption method and device |
| abstract | The embodiment of the application provides a homomorphic encryption method and a homomorphic encryption device, relates to the technical field of data processing, and is applied to participating nodes in a homomorphic encryption system, wherein the homomorphic encryption system comprises a homomorphic operation node and at least two participating nodes, and the homomorphic encryption method comprises the following steps: the participating nodes encode target plaintext data to be encrypted by using random noise data of the participating nodes to obtain target plaintext data; the participating nodes encrypt the target ciphertext data by using the shared symmetric key and send the encrypted target ciphertext data to the homomorphic operation node; the participating node receives ciphertext result data returned by the homomorphic operation node; the participating node decrypts the ciphertext result data by using the symmetric key to obtain decryption result data; and the participating nodes decode the decryption result data, and remove the random noise data of each participating node in the decoding process to obtain plaintext result data. The method and the device are used for improving the safety of data in the homomorphic calculation process. |
