Research And Implementation Of Communication Security In Software-Defined Industrial Internet Of Things

With the continuous maturity of cloud computing,the Internet of Things and big data technologies,the Industrial Internet of Things has risen and developed rapidly,but in the process of integration of IT(information technology)and OT(operational technology),a series of Problems and challenges.In order to solve these problems,software-defined networking is introduced into the Industrial Internet of Things in the industry.The introduction of software-defined networking solves some of the problems,but there are still many problems that need to be solved.In this article,we will mainly study the secure transmission of data in the software-defined Industrial Internet of Things.The specific research contents of this article are as follows:1.A lightweight encryption algorithm suitable for edge networks in the software-defined Industrial Internet of Things is proposed.This algorithm ensures the real-time performance of the algorithm by reducing the number of encrypted rounds and simplifying the encryption function.The introduction of non-linear correlation functions and an increase in key length increase the security of the algorithm.Therefore,it satisfies the requirements for real-time and security in a specific environment.2.A symmetric key management scheme suitable for software-defined industrial Internet of Things non-edge networks is proposed.This scheme effectively combines the advantages of software-defined networks to ensure the security of key distribution and update.In addition,This scheme improves the key update and key storage methods in the traditional key management scheme,thereby further ensuring the security and real-time in key management.At the same time,The improved key update method can effectively avoid network congestion caused by a large number of key updates.3.Designed and implemented a configurable dynamic encryption system.The system can match the best encryption algorithm based on the user's encryption requirements and runtime status,and then achieve data encryption and decryption.The system will count the latest runtime Data,which in turn uses runtime data to guide the matching of encryption algorithms.The system satisfies different encryption requirements in the Industrial Internet of Things,thereby ensuring the security of data in the Industrial Internet of Things.
