Abstract: This specification discloses model running methods, apparatuses, computer-readable storage media and systems. In an example method, an original model is split to obtain a basic model and a trusted execution environment (TEE) model; and data of the basic model and data of the TEE model are delivered to a terminal device, so that a rich execution environment (REE) in the terminal device runs the data of the basic model, and a TEE in the terminal device runs the data of the TEE model.

Abstract: The present disclosure provides a harmonic suppression apparatus, method, control unit, power supply apparatus, electric appliance equipment, and storage medium, wherein the harmonic suppression apparatus includes a tuning circuit module, which is connected with a first live wire and a second live wire of a three-phase power supply and is configured to perform resonance regulation processing; a PI-type resonant filtering circuit module, which is respectively connected with the tuning circuit module and a third live wire of the three-phase power supply and is configured to perform harmonic filtering processing on the first-phase current and the second-phase current processed by the tuning circuit module and a third-phase current; and a rectification circuit module, which is connected with the PI-type resonant filtering circuit module and is configured to perform rectification progressing and a power a load.

Abstract: Example methods, apparatuses, and computer-readable media for offline transaction processing are disclosed.

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.
