Abstract: A key distribution and receiving method includes obtaining, by a first key management center, NAF key information of the first network element and a NAF key of the first network element, wherein the NAF key information of the first network element is information required to obtain the NAF key of the first network element. A service key is obtained. Using the NAF key of the first network element to perform encryption and/or integrity protection on the service key, a first security protection parameter is generated. A first generic bootstrapping architecture GBA push message is sent to the first network element. The GBA push message carries the first security protection parameter and the NAF key information of the first network element.

Abstract: A discovery method and apparatus based on a service-based architecture, where the method includes a control network element sending a discovery response to a first functional network element, where the discovery response includes a determined security parameter and an access address or an identifier of a second functional network element. The first functional network element receives the discovery response from the control network element, and sends an access request to the second functional network element based on the address or the identifier of the second functional network element, where the access request includes the received security parameter. The second functional network element receives the access request from the first functional network element, verifies correctness of the security parameter, and determines, based on the correctness of the security parameter, whether the access request is authorized by the first functional network element.

Abstract: An Internet of Things (IoT) authorization method includes an IoT device that wirelessly communicates with a first electronic device and a second electronic device. A transmit distance of the second antenna is less than a transmit distance of the first antenna. When instructions stored in the memory are executed by the processor, the IoT device is configured to receive a first message indicating to add a shared control device for the IoT device; send, through the second antenna, a second message including device information of the IoT device; receive, in response to the second message, a third message including device information of the second electronic device; and send, through the first antenna, a fourth message including the device information of the second electronic device to the first electronic device.

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.
