Abstract
A method of data transmission is provided. The method includes: generating an encryption public key and an evaluation public key by interacting with other data providing ends; generating ciphertext data by encrypting local data with the encryption public key, and sending the ciphertext data to a data using end; receiving a ciphertext calculation result sent by the data using end, in which the ciphertext calculation result is determined by the data using end based on the evaluation public key and the ciphertext data received; and acquiring plaintext data by decrypting the ciphertext calculation result with a private key fragment of the data providing end.
