Abstract: A method for encrypting and decrypting data across domains based on privacy computing is provided. A data provider deploys a base key for a data user in advance, and when the data user needs to use the data at a later stage, the data provider generates a data token about a data key based on the base key, and then transmits encrypted data and the data token to the data user. The user obtains the data key based on its own base key in a privacy environment according to the data token, and uses the data key in the privacy environment to realize use of the encrypted data. A transmission process does not involve transmission of the key; therefore, even if a transmission channel is not secure, security of the data can still be ensured, and even if private data is used, the data itself cannot be obtained.
