IPv6 Routing Protocol for Low-Power and Lossy Networks (RPL) is the standard network layer protocol for achieving efficient routing in IPv6 over Low-Power Wireless Personal Area Networks (6LoWPAN). Resource-constrained and non-tamper resistant nature of smart sensor nodes makes RPL protocol susceptible to different threats. An attacker may use insider or outsider attack strategy to perform Denial-of-Service (DoS) attacks against RPL based networks. Security and Privacy risks associated with RPL protocol may limit its global adoption and worldwide acceptance. A proper investigation of RPL specific attacks and their impacts on an underlying network needs to be done. In this paper, we present and investigate one of the catastrophic attacks named as a copycat attack, a type of replay based DoS attack against the RPL protocol. An in-depth experimental study for analyzing the impacts of the copycat attack on RPL has been done. The experimental results show that the copycat attack can significantly degrade network performance in terms of packet delivery ratio, average end-to-end delay, and average power consumption. To the best of our knowledge, this is the first paper that extensively studies the impact of RPL specific replay mechanism based DoS attack on 6LoWPAN networks.

山寨攻击对物联网中基于RPL的6LoWPAN网络的影响

低功耗和有损网络的 IPv6 路由协议 (RPL) 是标准网络层协议，用于通过低功耗无线个人区域网络 (6LoWPAN) 在 IPv6 中实现高效路由。智能传感器节点的资源受限和非防篡改特性使 RPL 协议容易受到不同的威胁。攻击者可能使用内部或外部攻击策略对基于 RPL 的网络执行拒绝服务 (DoS) 攻击。与 RPL 协议相关的安全和隐私风险可能会限制其全球采用和全球接受。需要对 RPL 特定攻击及其对底层网络的影响进行适当调查。在本文中，我们介绍并调查了一种称为模仿攻击的灾难性攻击，这是一种针对 RPL 协议的基于重放的 DoS 攻击。已经进行了深入的实验研究，用于分析模仿攻击对 RPL 的影响。实验结果表明，山寨攻击可以显着降低网络性能，包括数据包交付率、平均端到端延迟和平均功耗。据我们所知，这是第一篇广泛研究基于 RPL 特定重播机制的 DoS 攻击对 6LoWPAN 网络的影响的论文。
