Tracebacking the Spoofed IP Packets in Multi ISP Domains with Secured Communication

Abstract

Internet protocol (IP) packet traceback system identifies the origin of the sequence of IP packets when the source addresses of these packets are spoofed. IP packet traceback is usually performed with the help of routers and gateways. Several approaches have been proposed to trace IP packets to their origin. The packet marking approach enables routers to probabilistically mark packets with partial path information and tries to reconstruct the complete path from the marked packets. In most of these approaches, routers and victims (affected systems) are considerably overloaded for marking the packet and reconstructing the trace path and requires more marked packets. This paper focuses on tracing the approximate source of attack instead of tracing the entire path in multi domain system without computation, by victim and also implementing security for authentication and confidentiality. It is assumed that Internet topology has been grouped as ISP domains
