A General Framework of Source Address Validation and Traceback for IPv4/IPv6 Transition Scenarios
IP spoofing always is bothering us along with the Internet invention. With the rapid development of IPv6 next generation Internet, this issue is more prominent. Existing IP anti-spoofing proposals, including SAVI(Source Address Validation Improvement) which was advocated by IETF, only focused on single-stack or simple network scenarios. To the best of our knowledge, none of them has paid attention to the IPv4/IPv6 transition scenarios. However, since transition schemes are plenty and various, one solution cannot meet all requirements of them. In this draft, we present a SAVI-based general frame-work for IP source address validation and traceback in the IPv4/IPv6 transition scenarios, which achieve this by extracting out essential and mutual properties from these schemes, and forming sub-solutions for each property. When one transition scheme is composed from various properties, its IP source address validation and traceback solution is directly comprised by the corresponding sub-solutions. Thus, the most exciting advantage of this framework is that it is a once-and-for-all solution no matter how transition schemes change.
