随着软件无线电技术在无线网络领域内的应用越来越广,传统的电子战干扰与新兴的无线网络赛博攻击之间的界线更加模糊。为了精确描述快速发展的无线安全领域内的这些新兴概念,文章提出了一种干扰机分类方法,以便对通信干扰机的理论行为和特点进行分类。与传统上根据干扰机所能干扰的信号类型进行分类相比,文章提出根据干扰机所拥有的信息及其利用信息的能力来分类。这些关键的干扰机能力包括干扰机是否具备时间相关性、协议感知能力、欺骗能力、学习能力。这些能力又可根据干扰机特性进行二级细分,包括干扰机的各种参数,如相对带宽、占空因数、调制方式、天线方向图以及该天线方向是否可控。最后,对当前相关文献中提出的干扰方法进行了抽样研究,并讨论如何将其归入本文提出的分类体系中。
As software and radio technologies become more widely used in wireless networks, the line between traditional electronic warfare attacks and the emerging wireless cyberspace attacks becomes more blurred. In order to accurately describe these emerging concepts in the fast-growing field of wireless security, a jammer classification method is proposed to classify the theoretical behavior and characteristics of communication jammers. In contrast to the traditional classification based on the types of signals the jammer can interfere with, the article proposes to classify the jammer based on the information it possesses and its ability to utilize the information. These key jammer capabilities include whether the jammer has time dependencies, protocol awareness, spoofing, or learning ability. These capabilities, in turn, can be subdivided into two levels based on jammer characteristics, including jammer parameters such as relative bandwidth, duty cycle, modulation scheme, antenna pattern, and whether the antenna direction is controllable. Finally, the sampling methods of the interference methods proposed in the current literature are studied, and how to classify them into the classification system proposed in this paper is discussed.
