Single Packet Hybrid IP Traceback for IPv4 and IPv6

What is it about?

DDoS attacks are one of the most serious cyber attacks on the Internet. To establish liability for these attacks, there is a need to scout for real attack sources. Schemes that identify the source of packets on the Internet are called IP Traceback schemes. Hybrid IP traceback schemes outdo discrete marking and logging approaches and trace the source of attack using a few packets. This paper proposes an efficient single packet hybrid IP traceback scheme for IPv4 as well as IPv6 networks.

Why is it important?

Our proposed scheme reduces the logging time at routers by 15%. Besides, the proposed scheme ensures zero false positives by encoding the Options field in IPv4 header. The research also introduces the first single packet hybrid IP traceback implementation for IPv6 networks using Hop by Hop extension header. The simulation results correctly demonstrate the viability of the proposed scheme and unveil that IPv6 implementation requires 82.5% less storage in contrast to existing work.
