Enhancing Data Plane Security Against Cyber Attacks for Wired and Wireless Communication Software Defined Networks Based on Encrypted Algorithms

Abstract

Information technology is constantly evolving in terms of structure, hardware, and software, and one of the most important areas of information technology that is continually updated is networks, which take up a large area in terms of development and innovation in
applications, services, tools, etc. Now is the time for Software Defined Networks (SDN) in wired and wireless topologies to emerge. SDN is a modern networking technology in which the data plane is separated from the control plane, and control functions are gathered in one device called a controller, which leads to many security problems and exposure to attacks by intruders. The aim of this article is to enhance data plane security against cyber-attacks for wired and wireless communication software-defined networks based on encrypted algorithms. In this article, a Developed Encryption Algorithm (DEA) is proposed to protect wired and wireless communication
SDN against malicious and cyber-attacks. The proposed algorithm was tested and verified by sending and receiving ten text files of different sizes through three scenarios of SDN topology, and then calculating the encryption and decryption time. Finally, the National Institute of Standards and Technology (NIST) test was applied to verify the complexity and strength of the proposed algorithm, and the DEA algorithm gives an accuracy of 95.39% as compared with the SG algorithm, which gives an accuracy of 94.93%.
