A sensor security defense technology in a mobile Internet of Things system

Abstract

The invention relates to the technical field of Internet of Things, and Specifically relates to a sensor security defense technology in a mobile Internet of Things system. an SDN technology based on Openflow is adopted to construct a sensor network technology platform system in the mobile Internet of Things system, and the system comprises a data link control system, a data communication forwarding system, an IP data packet content changing system and the like. The system is relatively easy to deploy and can be compatible with a traditional sensor network system; The top layer structure of thesystem is relatively transparent, any functional plug-in and third-party software do not need to be installed, and data communication and any correction do not need to be conducted on an original Internet of Things system; According to the technical scheme, communication of all the sensor equipment nodes in the system is protected, the data transmission link of the sensor equipment in the cross-region and Internet environment can be protected, and security defense protection of all the sensor equipment of the mobile Internet of Things system and the data communication process of the sensor equipment is achieved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a sensor security defense technology in a mobile Internet of Things system. Background technique [0002] The Openflow-based sensor security defense technology in the mobile Internet of Things system is a new type of defense technology. Through this technology, the protected Internet of Things devices are always in a state of constant change and movement relative to the public network, achieving protection Purpose of IoT system. Relevant research has been carried out on mobile Internet of Things system defense technologies at home and abroad. These technologies generally require the use of third-party software to achieve security defense technologies, or deploy new technical equipment, which is generally incompatible with existing Internet of Things systems. The problem. [0003] The relatively well-known foreign RHM and OF-RHM mobile device defense technologies ...

AI Technical Summary

Problems solved by technology

However, RHM defense technology requires all devices in the system to be Openflow switches, which is extremely difficult and costly to deploy, and cannot be compatible with existing networks. In actual work, it is impossible to replace all devices with Openflow switches.

OF-RHM only protects the communication node devices in the security defense area, and cannot achieve comprehensive system defense across areas (Internet)
