....on the network. Additionally, an attacker can prevent other computers from using IP based network services. The vulnerability can not easily be corrected because it is an error in the design of the protocol and not in its implementation. 2.1. 1 The Address Resolution Protocol Defined in RFC 826 [Plu82] ARP provides a mechanism for mapping higher level network addresses to hardware network addresses. The protocol enables hosts to use IP on Ethernet networks by mapping IP addresses to their corresponding Ethernet addresses. First, we examine the ARP request portion of the address resolution ....
....the system missing the attack. 2.1.4 Analysis of ARP Cache Poisoning ARP cache poisoning is not an implementation problem. The problem is in the specification of the protocol itself. In other words, the problem is not a software flaw, but it is flaw in the specifications laid down in RFC 826. Plu82] Because the RFC states that ARP replies will be honored regardless of whether the machine made an ARP request and without any form of authentication, the machine should trust that its ARP cache entries are correct only so much as it trusts the integrity of all of the other systems on the LAN. ....

....required to support seamless mobile communication. Conceptually, the base stations provide an illusion of a single wireless LAN that covers the entire campus. 3. 3 Initial Capture When a mobile host powers on and initiates communication, it emits a frame (e.g. an Address Resolution Protocol (ARP) [13] frame to query its default router s hardware address) that allows nearby base stations to detect its presence. Because a mobile host may be situated in an overlapping area, multiple base stations may receive the frame. To ensure that only one base station captures a new mobile host, base stations ....

....two steps. First, the sending host uses the receiving mobile s IP address to obtain the receiving mobile s physical address. Second, the sending host encloses the datagram in a frame and delivers the frame using the obtained physical address. The sender can use Address Resolution Protocol (ARP) Plu82] to automate the first step. To use ARP, the sender inserts the receiver s IP address in an ARP request and broadcasts the request. When it receives the request, the receiver sends a reply that contains its physical address directly to the sender [Plu82, Com95] To reduce the frequency of using ....

When it receives the request, the receiver sends a reply that contains its physical address directly to the sender [Plu82, Com95] To reduce the frequency of using ARP, a host uses an ARP cache to store the bindings of IP address to physical address.

....this section we are concerned with their description. 3.1 ARP and InARP The address resolution problem, e.g. determining a machine s MAC address given its network layer address, has been solved in many different ways. One well known solution in the case of Ethernet as the LAN technology is ARP ( RFC 826] A machine S determines the MAC address of another machine D by broadcasting an ARP request containing D s network protocol address. The machine that matches the network protocol address of an ARP request responds with an ARP reply containing D s MAC address. Inverse ARP 1 (InARP) is ....
