Abstract

Internet Control Message Protocol is a protocol which is mainly used to provide information relating to errors on networked machines. Considering the few controls that IP protocol carries out, it not only allows errors to be corrected but also informs the protocols of neighboring layers of these errors. So, ICMP protocol is used by all routers, who use it to indicate an error (called a Delivery Problem). ICMP error messages are sent over the network in a datagram form, like any other data. So, the error messages themselves can be subject to errors. ICMP messages are used by the network administrators for troubleshooting the networks. Even though this protocol has many advantages, there are some of the flaws such as security, which is a major concern to be considered and to be eliminated. In this paper, we present an existing scenario and provide the authentication mechanism for ICMP messages. We also propose enhanced Packet format for ICMP message in such a way that authentication can be done. Kerberos algorithm is used for authentication mechanism which uses private key encryption method.
