The Routing Protocol for Low Power and Lossy Networks (RPL) is experiencing a wave of security threats, due to the need of its utility in the Internet of Things (IoT). RPL is so far considered as one of the most utilized routing protocols in new IoT applications, which is one of the reasons the latter may lead to confronting challenges later on. In other words, security is thus the primary interest in RPL, regarding the nature of objects and their different constraints that are regularly regarded as security vulnerabilities for cyber-attacks. To continue, it is evident to claim that it is mandatory to determine and analyze all the kinds of attacks that target this protocol, such as the rank attack which is best known for its strongest threats that lead to degraded topology performance and energy consumption of nodes in the network. This study presents an overview of RPL, a proposed taxonomy of all the recent published works about rank attacks as well as the different mitigation methods, and the damage caused on network parameters. To conclude, a comparison between several attacks has been adopted using the Friedman test, and a discussion has been presented with some other recent research concerning security against rank attack.

RPL协议中针对等级攻击的安全性

由于需要在物联网（IoT）中使用实用程序，因此低功耗有损网络（RPL）的路由协议正遭受一波安全威胁。到目前为止，RPL被认为是新IoT应用程序中使用最多的路由协议之一，这是后者可能导致以后面临挑战的原因之一。换句话说，因此，关于对象的性质及其不同的约束（通常被视为网络攻击的安全漏洞），安全性是RPL的主要关注点。继续进行下去，显然声称必须确定和分析针对该协议的所有类型的攻击，例如以其最强的威胁而闻名的等级攻击，这种最强的威胁会导致拓扑性能和节点能耗下降在网络中。这项研究提供了RPL的概述，所有最近发表的有关等级攻击以及不同缓解方法以及对网络参数造成的损害的著作的拟议分类法。总而言之，已经使用弗里德曼测试对几种攻击进行了比较，并与其他一些有关针对等级攻击的安全性的最新研究进行了讨论。
