摘要/Abstract

摘要： 由于无线传感网中的传感节点受限于计算能力,电源能量、以及存储空间,如何确保无线传感网络的通信安全成为亟待破解的研究难点。基于此,旨在探讨如何应用压缩感知技术来保障无线传感网络的通信安全, 针对放大转发式压缩感知技术下的无线传感网络安全问题给出了安全可靠的通信信号重构算法,并且推导得到了压缩感知保密技术下的保密容量门限值。另外给出了无线传感网络不同节点参数条件下的无线传感网络保密容量的定量化分析。仿真结果进一步验证了所提安全通信方案的有效性。

Abstract: Due to the limitation of wireless sensor nodes on computation, power energy and storage space, the security issue has become a prevalent concern in the wireless communication. A deep insight on the secrecy capacity of wireless sensor network based on the Amplify-and-Forward (AF) compressed sensing scheme was offered providing a corresponding calculable capacity threshold. Moreover, a feasible algorithm based on augmented Lagrange method for the reconstruction of communication signals was proposed. Furthermore, the impact of the secrecy capacity was discussed to various numbers of active sensor nodes, relay nodes and eavesdropper nodes. Simulation results demonstrate the validity of the provided scheme.

Key words: wireless sensor networks, compressed sensing, physical layer security, distributed strategy, secrecy capacity
