Mitigation of Cyber Attacks in Software Defined Networking Framework

Day by Day the communication technology are evolving with new emerging technologies for sharing the information across the globe. The Fifth Generation is an effective technology to share the information by efficient utilization of spectrum. Since the Fifth Generation is an application oriented technology, Software Defined Networking is an efficient framework which paves the way for controlling the applications in 5G network. This Software Defined Networking framework divides both control plane and the data plane which programmatically controls all the networking operations. It is highly vulnerable to severe security based attacks and the possible major attacks are Denial of Service (DoS) Attack and Man In The Middle (MITM) attack. The proposed NAND Logic Based IP Address Encryption Decryption Algorithm (NLBIAEDA) defends MITM attack by encrypting and decrypting the IP address in both sender side and the receiver side. To mitigate the Denial of Service attack, the proposed Acceptance Based DOS Mitigation (ABDM) algorithm mitigates the DOS attack and reduces the network traffic automatically. The simulation results show that the IP address is more secure and the time of encryption and the time of decryption is reduced due to the usage of NAND gates which defends both Man in The Middle Attack and Denial of Service Attack.
