On Strategic Multi-Antenna Jamming in Centralized Detection Networks

Mitigating Jamming Attacks Using Energy Harvesting

The use of energy harvesting as a counter-jamming measure is investigated on the premise that part of the harmful interference can be harvested to increase the transmit power. We formulate the strategic interaction between a pair of legitimate nodes and a malicious jammer as a zero-sum game. Our analysis demonstrates that the legitimate nodes are able to neutralize the jammer. However, this policy is not necessarily a Nash equilibrium and hence is sub-optimal. Instead, harvesting the jamming interference can lead to relative gains of up to 95%, on average, in terms of Shannon capacity, when th…

Physical Layer Security Jamming: Theoretical Limits and Practical Designs in Wireless Networks

Physical layer security has been recently recognized as a promising new design paradigm to provide security in wireless networks. In addition to the existing conventional cryptographic methods, physical layer security exploits the dynamics of fading channels to enhance secured wireless links. In this approach, jamming plays a key role by generating noise signals to confuse the potential eavesdroppers, and significantly improves quality and reliability of secure communications between legitimate terminals. This article presents theoretical limits and practical designs of jamming approaches for …

Truthful Spectrum Auction for Efficient Anti-Jamming in Cognitive Radio Networks

One significant challenge in cognitive radio networks is to design a framework in which the selfish secondary users are obliged to interact with each other truthfully. Moreover, due to the vulnerability of these networks against jamming attacks, designing anti-jamming defense mechanisms is equally important. %providing the security defense is also of great importance. In this paper, we propose a truthful mechanism, robust against the jamming, for a dynamic stochastic cognitive radio network consisting of several selfish secondary users and a malicious user. In this model, each secondary user p…

Wireless Powered Cooperative Jamming for Secrecy Multi-AF Relaying Networks

本文研究了一组无线能量收集（WEH）启用放大转发（AF）中继执行合作干扰（CJ）和中继的帮助下的保密传输。网络中的源节点在第一阶段中与采用功率分配（PS）接收器的每个中继器进行同时无线信息和功率传输（SWIPT）;每个中继器进一步划分其收获的功率以用于转发接收到的信号并在第二传输阶段中生成用于干扰窃听者的人工噪声（AN）。在集中的情况下，与全球信道状态信息（CSI），我们提供了封闭形式的表达式的最佳和/或次优AF中继波束成形向量，以最大限度地提高可实现的保密率的中继的个人功率约束，使用半定松弛（SDR），这被证明是紧的技术。一个完全分布式的算法，仅利用本地CSI在每个中继也提出了作为一个性能基准。仿真结果验证了所提出的多AF中继与CJ比其他次优设计的有效性。
