Abstract

In this work, we study robustness of DTN routing in the absence of authentication. We identify conditions for an attack to be effective and present an attack based on a combination of targeted flooding and acknowledgement counterfeiting that is highly effective even with only a small number of attackers. Simulation results show that delivery ratio decrease by 30% to 50% using only 2 attackers for the two mobility patterns studied (Haggle and DieselNet). We observe that minimum hop count for packet delivery has a strong influence on the robustness of the DTN routing protocols. Generally, attacks become increasingly effective when the minimum hop count required increases. Further, use of global routing metadata in the routing protocol also increases attack effectiveness. Our study provides insights to the robustness of routing attacks in different DTNs settings and can be useful to DTN designers who want to choose the appropriate level of security that is needed for their respective scenarios.
DTN对路由攻击的鲁棒性
在这项工作中,我们研究了在没有认证的情况下DTN路由的鲁棒性。我们确定了攻击有效的条件,并基于有针对性的洪水和确认伪造的组合提出了一种攻击,即使只有少数攻击者也非常有效。仿真结果表明,对于所研究的两种移动模式(Haggle和DieselNet),仅使用2个攻击者,投送率降低了30% ~ 50%。我们观察到数据包传送的最小跳数对DTN路由协议的鲁棒性有很强的影响。通常,当所需的最小跳数增加时,攻击会变得越来越有效。此外,在路由协议中使用全局路由元数据也增加了攻击的有效性。我们的研究提供了对不同DTN设置中路由攻击的鲁棒性的见解,对于想要为各自的场景选择适当的安全级别的DTN设计人员来说是有用的。
