Multi-way access gateway device supporting wireless network and certification method

Abstract

The invention discloses a multi-way access gateway device supporting a wireless network, which comprises a microprocessor module, a local storage module, a liquid crystal display module, a ZigBee communication module, an RFID (Radio Frequency Identification Device) reader module, a Bluetooth communication module, a Wi-Fi module and a 3G communication module. An access certification method comprises three stages: user registration, certification and password changing. In the user registration stage, a user registers through an access device to become a legal use. In the certification stage, data required by the user are returned by a terminal node after mutual certification of each two of the user, the access device, the gateway device and the terminal node. In the password changing stage, the registered user inputs a new password into the access device and the stored information is updated. The wireless access based on the Bluetooth, Wi-Fi and 3G is realized, large quantities of wiring in engineering applications is avoided, the speed of device deployment is increased, and the security of the access to the gateway device by the user can be improved when the access certification method is adopted.

Description

Technical field [0001] The present invention relates to the field of communication technology, and further relates to a multi-mode access gateway device supporting wireless networks and an authentication method thereof, which can be used for the Internet of Things to realize the integration of multi-source detection and multi-sensing networks, while providing security for users to access the network Authentication equipment and its access method. Background technique [0002] RFID (Radio Frequency Identification, RFID) technology and wireless sensor network (ZigBee network) technology as the underlying information perception and collection technology have been rapidly developed with the application of the Internet of Things, and more and more are applied to the fields of industry and life. [0003] Currently, there are some gateway devices that support ZigBee technology, but these devices only support one or more of RFID, Bluetooth, Wi-Fi, and 3G wireless communication technologies...

AI Technical Summary

Problems solved by technology

For example, the establishment of Bluetooth and Wi-Fi connections requires a fixed password, which is easy to be stolen and embezzled; and after the connection is established, this authentication method also requires a dedicated authentication server and a secure authentication information transmission channel to complete user authentication. certification, resulting in additional equipment costs and increasing the complexity of the entire system
