Making DTNs Robust Against Spoofing Attacks With Localized Countermeasures

In this paper, the authors propose countermeasures to mitigate damage caused by spoofing attacks in Delay-Tolerant Networks (DTNs). In their model, an attacker spoofs someone else's address (the victim's) to absorb packets from the network intended for that victim. Address spoofing is arguably a very severe attack in DTNs, compared to other known attacks, such as dropping packets. Without a Public Key Infrastructure in DTNs, providing protection against this attack is challenging. They propose SPREAD (countermeasure against SPoofing by REplica ADjustment), a solution that assesses evidence of spoofing and offers countermeasures designed for quota-based multi-copy routing protocols.
