Problems solved by technology
However, the existing direct connection method does not have automatic online and automatic operation and maintenance capabilities. Every time an IoT gateway is added, operation and maintenance personnel need to go to the site to connect the device to achieve mutual access between the IoT gateway and the IoT platform; in addition , if the website of the IoT platform is changed, the operation and maintenance personnel also need to connect to the IoT gateway on site, which is not practical in scenarios with a large network scale and many IoT gateways, and there is no authentication process for the IoT gateway to go online
However, in the existing way of using DHCP Server to establish mutual visit relationship, although the automatic mutual visit between the Internet of Things gateway and the Internet of Things platform is realized, there may be multiple DHCP Servers in the Fabric network, which may cause acquisition The problem of address conflict is not conducive to unified management and unified planning of IP addresses
Moreover, the solution does not have a certification process for the Internet of Things gateway to go online.

The invention provides an authentication method and device. When the method is implemented by the Internet of Things gateway, the method comprises the steps: sending an authentication request message to an authentication server in an access network, wherein the authentication request message comprises authentication information of the Internet of Things gateway; receiving an authentication response message sent by the authentication server after the authentication of the Internet of Things gateway is passed, wherein the authentication response message carries a virtual extended local area network (Vxlan) identifier; sending a DHCP discovery message to a DHCP server in the access network, wherein the DHCP discovery message carries the Vxlan identifier; and receiving a DHCP response message sent by the DHCP server, wherein the DHCP response message carries access information of the Internet of Things platform, and the access information is determined by the DHCP server based on the Vxlan identifier.
Description
technical field [0001] The present application relates to the technical field of the Internet of Things, and in particular to an authentication method and device. Background technique [0002] At present, the mainstream fabric network is implemented by a core-aggregation-access network structure. Overlay virtualization technology (VXLAN) is used to implement network slicing, uniformly carry multiple virtual networks, and support flexible deployment of network services. With the development of IoT technology, the integration of IoT terminals and IoT gateways with existing Fabric networks has become an important part of regional network construction. IoT gateways need to be connected with network controllers + EIA (End-user Intelligent Access, terminal intelligent access server)+DHCP Server (Dynamic Host Configuration Protocol, dynamic host configuration protocol server), to realize the integration of the Internet of Things infrastructure and the core-convergence-access three-...
