Abstract: A first device and a home hub have a same TEE platform, and a second device and the home hub have different TEE platforms. A control method includes the home hub receiving an identity credential of the second device and public key information of the first device from the second device. The home hub controls an IoT device based on the identity credential of the second device. The home hub receives private key information that is of the first device and that is from the first device. The home hub forms an identity credential of the first device based on the public key information of the first device and the private key information of the first device to control the IoT device.

Abstract: This application provides a cross-device authentication method and an electronic device. The method is applied to a first electronic device. The first electronic device is connected to a second electronic device, and the method includes: The first electronic device receives a target operation performed by a user on a first interface of the first electronic device. The target operation is for triggering access to a first service, and the first service is associated with the second electronic device. The first electronic device obtains a target authentication manner corresponding to the target operation, and then the first electronic device acquires authentication information based on the target authentication manner, and sends an authentication request to the second electronic device.

Abstract: A remote monitoring method, a system and a storage medium for a sewage treatment process are provided. The remote monitoring method for the sewage treatment process includes steps of: collecting sensor data with a sewage treatment data collection platform, wherein the sewage treatment data collection platform has at least one sensor for collecting sewage data; establishing an abnormal situation detection platform with a deep learning technology to detect an abnormal situation of the sensor data, and raising an alarm if the abnormal situation occurs; establishing an abnormal situation diagnosis platform with the deep learning technology to diagnose the detected abnormal situation, so as to determine a type of abnormal situation; and using the sensor data to optimize and control parameters of the sewage treatment process based on the deep learning technology.

Abstract: A key negotiation method and an electronic device are provided, and relate to the field of communications technologies. Specifically, the method includes: An IoT control device multicasts, in a first local area network, a discovery message that carries a first public key, and sends a second ciphertext to a first IoT device after receiving a first ciphertext and a second public key. After receiving a third ciphertext from the first IoT device, the IoT control device decrypts the third ciphertext based on a first session key, to obtain a second signature and second session information; verifies the second signature based on a long-term public key of the first IoT device; and performs encrypted communication with the first IoT device based on the first session key after the second signature is successfully verified.
