Design of Secure ARP on MACsec(802.1AE)

MACsec provides authenticity and integrity for data frame on data link layer by implementing data encryption. For these advantages, MACsec is highlighted as a solution to protect and transmit data safely from the various security threats in the Wired and Wireless LAN. Until now, MACsec can not guarantee stable ARP management for itself [1]. This paper will propose a design of enhanced ARP to protect IP and MAC address from external threats and the enhanced ARP will encrypt ARP Packet by SAK (Secure Association Key) for the authentication. It will help to keep the address system safe from various security threats on data link layer.
