Internet of Things security architecture and information security interaction method thereof

Abstract

The invention relates to an Internet of Things security architecture and an information security interaction method thereof. The Internet of Things security architecture comprises a sensor node group,a main node cluster group and an aggregation node, wherein the sensor node group comprises a sensor main node and a plurality of sensor member nodes, and the sensor main node and the sensor member nodes are communicated in an identity verification mode; the main node cluster group comprises a clustering main node and a plurality of sensor main nodes, and the clustering main node and the sensor main nodes are communicated in an identity verification mode; the aggregation node is used for aggregating all information of the clustering main node; and the sensor node group and the main node cluster group are divided according to the operation remaining capacity of the sensor main node or the clustering main node and the distance between the nodes. The capability of the main nodes is fully exerted to implement various network security supervision, so that the security of the Internet of Things is enhanced.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to an Internet of Things security framework and an information security interaction method thereof. Background technique [0002] The Internet of Things (IOT) refers to the real-time collection of any information that needs monitoring, connection, and interaction through various devices and technologies such as information sensors, radio frequency identification technology, global positioning system, infrared sensors, and laser scanners. Objects or processes, collect various required information such as sound, light, heat, electricity, mechanics, chemistry, biology, location, etc., and realize the ubiquitous connection between things and things, things and people through various possible network access , to achieve intelligent perception, identification and management of items and processes. The Internet of Things is an information carrier based on the Internet, traditiona...

AI Technical Summary

Problems solved by technology

[0003] In the process of realizing the present invention, the inventors found the following technical problems: Since the Internet of Things is usually deployed first and signed later, and various sensor nodes exchange various information with each other, it is impossible to build a unified security architecture for the Internet of Things. Its security is constrained by loose security protocols

However, most sensor nodes are limited by hardware, and it is difficult to completely implement all security protocols, which seriously affects the security of the Internet of Things.
