     A General Framework of Source Address Validation and Traceback for
                      IPv4/IPv6 Transition Scenarios

Abstract

   IP spoofing is a critical breach regard to Internet security. With
   rapid development of the IPv6-based next generation Internet, this
   issue is more prominent since IPv6 Internet owns more spoofable IP
   address space. 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 IPv4/IPv6 transition schemes are
   plenty and various, one solution cannot meet all requirements of them.
   In this draft, we present a SAVI-based general framework 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.
