摘要： 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.

摘要： A packet transmission method includes generating, by a first router, a first routing information update packet; generating, by the first router, a first source-tracing packet, where the first source-tracing packet is used to indicate that the first router is a source router generating the first routing information update packet; and determining, by the first router, that a second router adjacent to the first router has a source-tracing capability, and sending the first source-tracing packet to the second router.

摘要： An identity authentication method and a mobile device. The mobile device performs receiving a first message of an electronic device within a second distance from the electronic device, where the first message includes a randomly generated session key, randomly generating first action information in response to the first message, and obtaining a second message by encrypting the first action information using the session key, sending the second message to the electronic device. displaying first confirmation information to determine whether the electronic device performs a first action indicated by the first action information, receiving first input used for confirmation, and prompting that identity authentication on the electronic device succeeds, where the second distance is less than or equal to a preset secure distance.
