Equipment node authentication method, device and system

Abstract

The invention discloses an equipment node authentication method, device and system, and the method comprises the steps: receiving a networking application request transmitted by a to-be-authenticatedequipment node, wherein the networking application request carries an association relation between the equipment identification information of the to-be-authenticated equipment node and the identification information of an IOT card; selecting a plurality of equipment nodes, forwarding the networking application request to the selected equipment node, and authenticating the equipment node to be authenticated by the selected equipment node according to the received association relationship; and receiving an authentication result sent by the selected equipment node, and determining a final authentication result of the to-be-authenticated equipment node according to the authentication result sent by each equipment node. The base station authenticates the device node to be authenticated by using the selected device node, and does not need to perform authentication completely on the network side like the prior art, so that the occurrence of network congestion caused by massive authenticationon the network side in the prior art is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a device node authentication method, device and system. Background technique [0002] The IoT business scenarios are numerous and complex, and the terminal forms are diverse. In order to facilitate adaptation and promotion, a plug-in card is designed, but the card is easy to be used maliciously. For example, a terminal using a plug-in card is difficult to prevent the card from being separated, and there is a risk of being used for business abuse such as sending spam messages. [0003] There are generally three existing IoT card authentication methods, namely: terminal-side machine-card authentication, network-layer machine-card authentication, and subscriber identity module (Subscriber Identity Module, SIM) authentication. The inventor found that the Internet of Things will be widely used in the future, and the terminals will be diverse and difficult to unify stan...

AI Technical Summary

Problems solved by technology

The inventor found that the Internet of Things will be widely used in the future, and the terminals will be diverse and difficult to unify standards. However, the machine card authentication method on the terminal side will inevitably have certain technical requirements for the terminal itself. Some terminals (such as street lamps, water meters, etc.) have already completed construction. It is difficult for terminal manufacturers to accept the large investment in the transformation of machine card authentication technology

In network-side authentication, machine-card authentication is required for various services and a large number of terminals accessing the network. If network-side machine-card authentication is adopted, massive nodes may cause network authentication blocking risks.

Completing the binding and authentication calculations in the SIM has high requirements on the performance and security of the SIM card, requiring a lot of investment in the SIM card, and the SIM card is a single point of decision-making, which has a high security risk
