Sensing layer-oriented Internet of Things trusted connection method and system

Abstract

The invention provides a sensing layer-oriented Internet of Things trusted connection method and system, the Internet of Things comprises a sensing layer node, a cluster head node and an aggregation node, and the method comprises the following steps: the sensing layer node sends a network access request to the aggregation node and the cluster head node respectively; the sensing layer node responds to information returned by the aggregation node and the cluster head node according to the network access request to execute bidirectional identity authentication of the sensing layer node and the aggregation node and bidirectional identity authentication of the sensing layer node and the cluster head node; if the two-way identity authentication is passed, platform credibility identification and platform integrity verification are executed; and if the platform credibility identification and the platform integrity verification are both passed, trusted network connection is established. According to the method, bidirectional authentication and behavior attribute authentication of each node are realized, and the method has good applicability to the nodes in the Internet of Things, has the characteristics that the nodes can be monitored and measured, can guarantee the credibility of data information, and improves the availability of the network.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a method and system for trusted connection of the Internet of Things oriented to the perception layer. Background technique [0002] An important task of the perception layer of the Internet of Things is network connection. When connecting to the network, the nodes of the perception layer adopt an identity authentication mechanism, but the credibility of identity authentication does not mean the credibility of node functions. Therefore, the existing identity authentication mechanism The access of illegal terminals cannot be resisted, so the network connection of the Internet of Things is not safe. [0003] The importance of node identity in the network connection model of the Internet of Things is greater than that of nodes in the traditional network connection model. The rapid development of the Internet of Things has brought more and more serious security threats...

[0002] An important task of the perception layer of the Internet of Things is network connection. When connecting to the network, the nodes of the perception layer adopt an identity authentication mechanism, but the credibility of identity authentication does not mean the credibility of node functions. Therefore, the existing identity authentication mechanism It cannot resist the access of illegal terminals, so the network connection of the Internet of Things is not safe

[0003] The importance of node identity in the network connection model of the Internet of Things is greater than that of nodes in the traditional network connection model. The rapid development of the Internet of Things has brought more and more serious security threats, and general identity authentication cannot achieve IoT Security Requirements
