Abstract: A storage circuit stores secret information. A software processing circuit obtains an operation task and generates scheduling instructions corresponding to the operation task. After receiving the scheduling instructions, a hardware processing circuit obtains the secret information from the storage circuit when the flag bit in the scheduling instruction is a valid value, determines, based on the secret information, data addresses of one or more pieces of operation data required for completing the operation corresponding to the scheduling instruction, and obtains the one or more pieces of operation data based on the data addresses to complete the operation corresponding to each scheduling instruction.

Abstract: A method for transmitting data comprising a data requester sends, to a data sender, a data request that carries an identifier of the data requester and a category of requested data. After receiving the data request, the data sender generates an identifier public key using the identifier of the data requester and the category of the data. The data sender encrypts the data requested by the data requester using the identity public key, and sends the encrypted data and identity public key indication information to the data requester. The data requester decrypts the encrypted data using an identifier private key corresponding to the identifier public key to obtain the requested data, and the data requester performs decryption using the identifier private key.
