Abstract

The lack of verifying source address in Internet makes it easy for attackers to spoof the source IP address. One of challenges of Internet has been recognized is building mechanisms in routers to verify the source address. This paper discusses Source Address Spoofing Prevention (SASP) mechanisms, presents a formal description on SASP network and SASP router, proposes a hierarchical SASP architecture, and presents some design principles of SASP mechanisms.
