The invention provides a verifiable training classification model in a mobile communication system and a classification method of the verifiable training classification model, relates to the technical field of cloud services, designs a cloud edge collaborative classifier training framework capable of protecting privacy, and safely outsourcing time-consuming operation to an ES (Extended Station) so as to reduce the calculation burden of SMD (Surface Mount Device) and CS (Circuit Switching). Meanwhile, the calculation efficiency of classification service can be improved, and the data volume is increased. Secondly, an algorithm library based on multi-key fully homomorphic encryption is further designed, and the algorithm library supports distance and comparison calculation operation of encrypted data. In addition, the algorithm library can also construct other privacy protection classifier training services in a modular mode. Finally, a classification method capable of verifying the training classification model in the mobile communication system is provided, and lightweight integrity verification is achieved. The SMD only needs to execute a simple online signature operation, and most of time-consuming offline operations are safely outsourced to an edge service, so that any encrypted aggregated data is ensured not to be replaced or tampered before being decrypted.

A storage device includes a memory device and a storage controller including a security management module to manage security data of the storage device. The security management module includes a security manager to receive a command related to the security data, determine a current security mode of the storage device in response to receiving the command, and control access to the security data based on the current security mode. The current security mode includes one of a first security mode in which the security manager allows access to the security data, a second security mode in which the security manager allows limited access to the security data, and a third security mode in which the security manager prevents access to the security data.
