Description
Technical Field
The 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
Along with the popularization of networks, more and more wifi intelligent household appliances enter the market, and how to quickly and conveniently perform identity authentication and realize safe access to equipment is a problem to be solved urgently. The existing main authentication modes include two modes of server authentication and device fixed access code authentication.
The authentication mode based on the server is as follows: after the mobile phone terminal accesses the intelligent household appliance, triggering an authentication flow of the intelligent household appliance, and simultaneously sending authentication information to the mobile phone terminal and the intelligent household appliance by the remote authentication server; the mobile phone end sends the authentication information to the intelligent household appliance, and the intelligent household appliance performs authentication by using the received authentication information and determines whether to accept the access request of the mobile phone end. The method needs the equipment to synchronize the user information with the server, and the user information cannot be completed in the local area network independently, so that the universality is poor.
The authentication mode based on the equipment fixed access code is as follows: and after the mobile phone terminal is connected into the intelligent household appliance, sending an access code built in the intelligent household appliance, authenticating the intelligent household appliance, and determining whether to accept the access request of the mobile phone terminal. The authentication mode requires an input device on the equipment, which is not beneficial to wide application; or require a fixed access code to be preset, increasing production costs and requiring after-market maintenance.
The two authentication modes both require the user to input, so that the user experience is greatly reduced.
