  Abstract

SDN(Software Defined Network) can manage the functions and services of the network through central control. However, SDN, like traditional networks, is able to identify network resources by IP address exposure and there are vulnerabilities to IP spoofing, sniffing, network scanning, and DoS using IP addresses. In order to solve this problem, a technology that continuously changes the environment is being studied to delay or prevent an attack on the system in the pre-attack preparation stage. This paper proposes a method of encrypting the IP address using a format-preserving encryption to protect the IP address from network security threats such as sniffing and spoofing while minimizing the change of the protocol structure. In the key distribution process, host authentication was used to counter attacks such as non-repudiation and flow rule conflict. In addition, experiments results showed that approximately 32% of hosts are safe for network scanning attacks. As a result, we confirmed that our proposal is better than the existing resource protection technology in the security.
