无线传感器网络安全研究

Research on the Security in Wireless Sensor Network

随着传感器网络研究的深入和不断走向实用,安全问题引起了人们的极大关注。由于传感器节点的计算速度、电源能量、通信能力和存储空间非常有限,且一般配置在恶劣环境、无人区域或敌方阵地中,这给传感器网络安全方案的设计提出了诸多挑战。本文分析了无线传感器网络(WSN)的安全需求,并从密钥管理、身份认证和攻防技术三个方面归纳了国内外传感器网络安全问题的研究进展情况。最后,基于对传感器网络安全未决问题的分析和评述,指出了今后该领域的研究方向。

As sensor networks edge closer towards wide-spread deployment,security issues become a central concern. Typical sensors posses limited computation,energy,computation,memory resources and they are always deployed in a harsh,unattended or hostile environment,so the security issues posed by sensor networks represent a rich and chal- lenging field of research problems. In this paper,we propose various security requirements with regard to Wireless Sensor Network(WSN). Furthermore, we analyze status quo of WSN from three aspects: keymanagement,identity au- thentication as well as attacks and counter-measures. In conclusion,we point out its development direction based on the analysis and remark of problems remaining unsolved in WSN.
