ABSTRACT
IPv6 offers a number of other key design improvements over IPv4. IPv6 provide improved efficiency in routing and packet handling. And IPv6 can provide end-to-end security services such as access control, confidentiality, and data integrity with less impact on network performance. However, we can also prospect that there will be much more dangerous and tremendous type of attack on IPv6 than that on IPv4. So, we must consider on the advanced IP traceback function for tracing the spoofed real source on IPv6 packet using authentication mechanism. Proposed authentication mechanism supports the key disclosure mechanism on packet marking on the process of IP traceback.
