SERVICE DATA PROCESSING METHOD

原文（中国語）

In a data processing method, in response to a trigger event of a target service, service data corresponding to the target service is obtained. An encryption key corresponding to the target service is obtained. The encryption key is generated by a server of the target service by encrypting a dynamically generated service key based on a pre-stored first root key. Based on a pre-stored second root key, the encryption key is decrypted to obtain the service key. The first root key and the second root key form a set of symmetric keys. The service data is encrypted based on the service key to generate intermediate data. The intermediate data is transmitted to the server. An execution result generated by the server based on the service data is received, The server decrypts the intermediate data based on the service key to obtain the service data.
