Investigating ARP poisoning

Address Resolution protocol (ARP) is used to map logical addresses into its corresponding physical addresses and is widely used protocol in TCP/IP network. ARP protocol doesn't provide any mechanism for authentication amongst hosts in the network. On other hand it is a stateless protocol. These limitations make ARP protocol vulnerable to attacks. ARP poisoning is a type of Man-In-The-Middle (MITM) in which attacker poisons the ARP cache of two hosts and place itself between legitimate traffic. In this work we implemented ARP poisoning using Ettercap and Cain and Abel tool. The work gives the systematic literature reviews of techniques for mitigation of ARP poisoning and bitcoin based model is proposed. The proposed model is based on the bitcoin networks and bitcoin cryptography. Our proposed scheme can efficiently mitigate the ARP poisoning attack as authentication is achieved through digital signature which can only be generated by legitimate host with their private key. Also, other host in the same network can check whether the communication between two hosts is authentic or not.
