Abstract
Data processing includes acquiring service data of a target service by using a trusted application in a trusted execution environment (TEE), generating a service session key corresponding to the target service, and transferring the service data and the service session key to a secure element and encrypted based on the service session key to obtain service ciphertext information, and encrypting the service session key based on a target service key to obtain a service session key ciphertext. A key identifier of the target service key, the service ciphertext information, and the service session key ciphertext are sent to a server device to determine the target service key, which is used to decrypt the service session key ciphertext to obtain the service session key, which is used to decrypt the service ciphertext information to obtain the service data of the target service to perform target service processing.
