A secure packet marking scheme for IP traceback in IPv6

The growing threat of cyber attacks, especially the DDoS (Distributed Denial of Service Attack) makes the IP Traceback very much prevalent to today's Internet security. IP Traceback is one of the security concerns that is associated with finding out the true origin of the attack/attacker. This process is very cumbersome as the IP addresses in most cases are spoofed addresses. The techniques that are used at present were designed for IPv4. Although IPv6 overcomes some of the security risks that could not be addressed at the protocol level, some problems are yet to be addressed. In addition to this, the prevailing traceback schemes need to be modified prior to their use in IPv6. Our approach in this paper focuses on a secure packet marking mechanism that would help in obtaining the marking which are authentic which a desired criteria for an improved marking scheme.
