Description

A smart home appliance and a method and device for safely accessing the smart home appliance

technical field

The present invention relates to the technical field of local area network communication, in particular to an intelligent household appliance and an access method and device thereof.

Background technique

With the popularity of the Internet, more and more wifi smart home appliances have entered the market. How to quickly and conveniently perform identity authentication and secure access to devices is an urgent problem to be solved. There are two main existing authentication methods: server-based authentication and device-based fixed access code authentication.

The server-based authentication method is: after the mobile terminal is connected to the smart home appliance, the authentication process of the smart home appliance is triggered, and the remote authentication server sends the authentication information to the mobile terminal and the smart home appliance at the same time; the mobile terminal sends the authentication information to the smart home appliance, and the smart home appliance has already used The received authentication information is authenticated to decide whether to accept the access request from the mobile terminal. This method requires the device to be able to synchronize user information with the server, which cannot be done in the local area network alone, and is not universally applicable.

The authentication method based on the fixed access code of the device is: after the mobile terminal is connected to the smart home appliance, it sends the built-in access code of the smart home appliance, and the smart home appliance performs authentication to decide whether to accept the access request from the mobile phone terminal. This authentication method requires the device to have an input device, which is not conducive to wide application; or requires a preset fixed access code, which increases production costs and requires after-sales maintenance.

The above two authentication methods both require user input, which greatly reduces the user experience.
