泊松网络安全通信中的协同干扰

Friendship-based Cooperative Jamming for Secure Communication in Poisson Networks

Yuanyu Zhang, Yulong Shen, Hua Wang, Xiaohong Jiang

摘要:

考虑到网络节点之间的社会关系的无线网络对于许多重要的数据通信服务具有高度吸引力。确保这些网络的安全性对于促进其应用以支持具有强安全保障的未来基于社会的服务具有重要意义。研究了有限泊松网络中基于物理层安全的安全通信问题,提出了一种基于社会友谊的协同干扰方案.该干扰方案由本地友谊圈(LFC)和远程友谊环(LFA)组成,LFC中的所有合法节点都充当干扰源,而LFA中的合法节点则通过三种基于位置的策略被选择作为干扰源。为了理解所提出的干扰方案的安全性和可靠性性能,我们首先通过推导其拉普拉斯变换在两个典型的路径损耗情况下在网络中的任何位置的干扰和模型。借助干扰拉普拉斯变换的结果,推导出传输中断概率(TOP)的精确表达式,并确定了保密中断概率(SOP)的上下界,从而可以描述干扰方案的整体中断性能。最后,我们提出了大量的数值结果来验证TOP和SOP的理论分析,也说明了基于友谊的合作干扰对网络性能的影响。

英文摘要:

Wireless networks with the consideration of social relationships among network nodes are highly appealing for lots of important data communication services. Ensuring the security of such networks is of great importance to facilitate their applications in supporting future social-based services with strong security guarantee. This paper explores the physical layer security-based secure communication in a finite Poisson network with social friendships among nodes, for which a social friendship-based cooperative jamming scheme is proposed. The jamming scheme consists of a Local Friendship Circle (LFC) and a Long-range Friendship Annulus (LFA), where all legitimate nodes in the LFC serve as jammers, but the legitimate nodes in the LFA are selected as jammers through three location-based policies. To understand both the security and reliability performance of the proposed jamming scheme, we first model the sum interference at any location in the network by deriving its Laplace transform under two typical path loss scenarios. With the help of the interference Laplace transform results, we then derive the exact expression for the transmission outage probability (TOP) and determine both the upper and lower bounds on the secrecy outage probability (SOP), such that the overall outage performances of the proposed jamming scheme can be depicted. Finally, we present extensive numerical results to validate the theoretical analysis of TOP and SOP and also to illustrate the impacts of the friendship-based cooperative jamming on the network performances.
