Problems solved by technology
However, if you directly put the salary plaintext on the cloud, the enterprise information will be exposed to the server, and the information security cannot be guaranteed. If you store the salary ciphertext data in the cloud, any calculation of the salary data at this time needs to first convert the ciphertext salary data from The cloud downloads to the client, and then the client decrypts the ciphertext salary data to obtain the plaintext data, and then performs related calculation processing on the plaintext salary data, which greatly increases the data calculation burden of the client

The invention provides a data encryption, decryption and processing method and device, equipment and a storage medium, and the encryption method comprises the steps: obtaining a key corresponding to to-be-processed data, wherein the order of magnitude of the key is greater than the order of magnitude of the to-be-processed data; and performing target homomorphic encryption processing on the to-be-processed data according to the key corresponding to the to-be-processed data to obtain ciphertext data of the to-be-processed data. According to the data processing method and device, homomorphic encryption processing is conducted on the to-be-processed data through the secret key with the order of magnitude larger than the order of magnitude of the to-be-processed data, the ciphertext data of the to-be-processed data can be obtained, polynomial operation can be directly conducted on the ciphertext data of the to-be-processed data, and the information leakage risk caused by direct plaintext data operation is avoided.
Description
technical field [0001] The present application relates to the technical field of information security, in particular, to a data encryption, decryption, processing method, device, device and storage medium. Background technique [0002] With the development of the Internet and the birth of the concept of cloud computing, as well as the increasing demand for ciphertext search, electronic voting, mobile code and multi-party computing, homomorphic encryption (Homomorphic Encryption) has become more important. Homomorphic encryption is a kind of encryption method with special natural properties. This concept was first proposed by Rivest et al. in the 1970s. Compared with general encryption algorithms, homomorphic encryption can not only realize basic encryption operations, but also A variety of calculation functions between ciphertexts can be realized, that is, calculation before decryption is equivalent to decryption before calculation. This feature is of great significance for...
