A General Framework of Source Address Validation and Traceback for
IPv4/IPv6 Transition Scenarios
draft-xu-savi-transition-03.txt
Abstract
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. Though many studies have made their
contributions to the prevention of IP-spoofing, the most excellent
one is the SAVI (Source Address Validation Improvement) proposal
advocated by IETF, since it can prevent IP-spoofing from happening by
automatically binding the key properties of hosts in layer2 access
subnet. Nevertheless, till now, SAVI only focuses on the IPv6 stack
and simple network access scenarios. To the best of our knowledge,
there is no solution even has paid attention to IPv4/IPv6 transition
scenarios. Given the fact that IPv4/IPv6 transition will continue to
be adopted for a long period of time, this issue is becoming
increasingly urgent. However, since transition schemes are plenty and
diverse, hardly can an ordinary solution satisfy all the requirements
of various transition scenarios. In this document, we present an
improved general SAVI-based framework of IP source address validation
and traceback for IPv4/IPv6 transition scenarios. To achieve this
goal, we extract essential and mutual properties from these
transition schemes, and create sub-solutions for each property.
Naturally, if one transition scheme is proposed by combining some
properties, the corresponding sub-solutions would be included into
its IP source address validation and traceback solution. Therefore,
the advantage of this framework is its capability to adapt to all the
transition schemes.
