Abstract
Some embodiments of this specification disclose data encryption and data preprocessing. In an implementation, a method includes for online data encryption: generating, based on plaintext data, a second component of ciphertext data. From a data set and as a selected first component of ciphertext data, a first component of ciphertext data is selected. Based on the first component of ciphertext data and the second component of ciphertext data, ciphertext data of plaintext data is calculated. For offline data preprocessing, the first component of ciphertext data is generated and plaintext encryption uses the first component of ciphertext data and the second component of ciphertext data. Alternatively, a data acquisition request is received, the first component of ciphertext data is generated, and fed back, and stored for use in plaintext encryption.
