The Research on ARP Protocol Based Authentication Mechanism
Yongzhen Li, Jing Li · 2016
ARP protocol is one of the basic agreement in TCP/IP network protocol, but ARP protocol is not safe, because it does not verify the source of the ARP packet is legal or not, in this case lead to variety ARP attack in the local area network (LAN) with the lack of authentication mechanism in ARP protocol, like man-in-middle attack, flooding attack, IP address conflict attack, gateway attack and so on.In this paper, in light of the present condition of the ARP protocol is easy to be attacked, Design authentication mechanism about regulate the request-reply sequence of ARP message and application it in ARP protocol.The simulation result of OPNET indicates new protocol can defense variety of ARP attack effectively in the case of small cost.
