Research on matrix entropy value between industrial ethernet data and internet data based on information entropy

Abstract

The adoption of network technology for control and measurement makes Industrial Control Systems (ICSs) and Internet of Things (IoTs) more and more powerful, whose communication data plays an important role to realize data intercommunication and sharing. However, communication data have different characteristics, even if the same communication protocol is used in ICS or IT, the communication characteristics and modes are quite different. In order to understand the difference of communication data between internet and industrial ethernet, in this paper, we conduct a series of experiments that use information entropy algorithm to data changes based on different industrial protocol and http protocol, which always is used to measure the uncertainty and describe the uncertainty of data packets. The experimental result analysis shows that there exists a big difference in industrial ethernet data and internet data, the industrial ethernet data are more relatively balanced and more regular than those of internet data.
