Embodiment Construction

[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0030] In order to better understand the present invention, the communication mode between the smart device and the client in the traditional mode is firstly described.

[0031] When traditional client A and smart device B1 communicate and interact, the identity authentication of client A and smart device B1 is performed based on a private protocol. However, if figure 1 As shown, when the illegal third-party device C obtains the private protocol, it can pretend to be the client A to communicate with the smart device B1, or it can...

Abstract

The invention discloses a data communication method, device and equipment of an intelligent device, wherein the method includes: obtaining equipment information of an intelligent equipment, and matching the registered equipment corresponding to the equipment information pre-stored in the cloud / server according to the equipment information Public key; verify whether the registered device public key is the same as the local device public key stored locally on the smart device, and if they are the same, obtain the device certificate of the smart device so that the client can use the device certificate and registered device public key to exchange business data with the smart device communication. As a result, the reliability of security authentication when the smart device performs data communication is improved, and no cluster reaction is caused, the randomness is strong, and the security is higher.

Description

technical field [0001] The present invention relates to the technical field of smart home communication, in particular to a data communication method, device and equipment for smart devices. Background technique [0002] With the development of computer technology, major changes have taken place in the production and life of users. Users can control smart devices such as household appliances on the client side of devices such as smart phones. Among them, when controlling other smart devices, before the smart device communicates with the cloud / server, as well as the smart device and the client, it needs to pass mutual authentication, and after the authentication is passed, a secure link is established and realized through the established secure link. Interaction of business data. [0003] In the related technology, the private protocol of the smart device manufacturer is used to realize the authentication with the client. However, once the private protocol is leaked or illeg...
