Design And Implemention Of Security Gateway Software In Internet Of Things

As the Internet of Things(IoT)has a closer relationship with the Internet,various information can be instantly picked up through the Internet.Via super computer groups,real-time management and control of people,devices,machines,and infrastructure can be achieved in the whole network,which makes us to manage our work and life in a precise manner,achieve a wisdom lifestyle and improve resource utilization and productivity.As the key device for the IoT system,IoT gateway plays a significant role in setting up the IoT.In this paper,we focus on designing a security IoT gateway software on the demand side of IoT application.The design of the software is considered from two aspects: system function and security.The main work is as follows:Based on the analysis of IoT structure and gateway funtion,we deeply analyze the software requirements of IoT,design the overall framework scheme of Io T gateway software,divide the software into multiple modules according to the system function and security requirements and describe them separately.We carry out a detailed design and implementation for the modules in the framework scheme,including detailed functional design of each module,interface design between the modules and process design.We pay more attetion to the design of security from the aspects of data privacy protection,data integrity protection,data transmission protection and so on.We realize the funtion of each module through programming,and carry out the debugging of each module and the whole gateway software.Combined with the hardware platform,we complete the development of a fully functional IoT gateway device.Finally,we test the system function and the security of the gateway device,the result shows that the gateway device meets the specific needs of the application scenarios.At present,the device has been productized,mass produced,on sale and applied to the real IoT environment.
