The invention relates to the technical field of smart home, and discloses a method for device identity authentication. The method comprises the following steps: a cloud platform encrypts a second address and first authentication information of an edge computing node through a first key to obtain a second encrypted address and first encrypted authentication information, and encrypts a first address and second authentication information of terminal equipment through a second key to obtain a first encrypted address and second encrypted authentication information, the second encrypted address and the second encrypted authentication information are sent to the terminal equipment, and the first encrypted address and the first encrypted authentication information are sent to an edge computing node; the terminal equipment authenticates the edge computing node according to the first encryption authentication information sent by the edge computing node and the first authentication information sent by the cloud platform; the edge computing node authenticates the terminal equipment according to the second encryption authentication information sent by the terminal equipment and the second authentication information sent by the cloud platform. Therefore, the terminal equipment and the edge computing node can complete bidirectional authentication.
Description
technical field [0001] The present application relates to the technical field of smart home, for example, to a method, device and smart home system for device identity authentication. Background technique [0002] At present, the edge computing nodes of the smart home need to be registered on the cloud platform of the smart home, and the terminal devices need to be registered on the edge computing nodes. The edge computing nodes undertake part of the computing and storage capabilities of the cloud platform. The existing registration scheme is as follows: the smart home cloud platform has the public key of the edge computing node, and the edge computing node has a built-in private key, and the two-way authentication between the smart home cloud platform and the edge computing node is completed through the key pair; The public key, the built-in private key of the terminal device, completes the two-way authentication between the edge computing node and the terminal device throu...
