Abstract

It is certain that IP spoofing remains a serious issua at present over the Internet. Our work in this thesis is to offer an authentic source identifier which may be employed by a network for IP spoofing packets. In this thesis, we provide an original model together with an examination of a Spoofing Defence System (SDS) in an Autonomous System (AS) level designed for filtering the spoofed IP packets. An Inter-Domain Routing Validator (IRV) handles the secret keys and exchange keys among different ASes via a secure communication channel. As it is a secure system, the SDS is definitely effective and easily employed cooperatively with other defence systems.
