无线传感器网络安全研究

Study on the Safe of Wireless Sensor Network

无线传感器网络(Wireless Sensor Network,WSN)是由一组传感器以自组织方式构成的无线网络,被认为是未来改变世界的十大技术之首,但有限的计算、存储和通信能力,尤其是严重受限的能量使其应用前景面临巨大挑战,这些特点也使得传统网络的机制无法直接用于无线传感器网络。无线传感器网络在应用之前需要解决很多关键问题,安全问题即是其中之一。随着无线传感器网络受到越来越多的关注,其安全问题也变得越来越重要。本文首先分析了无线传感器网络的特点和需要解决的安全问题,然后根据各层面临的威胁分别给出了应对的策略,重点分析了网络路由层的安全威胁以及具体的解决方案。

Wireless sensor network（WSN） is a wireless network which is made up of some sensors by self-organizing. It is believed to be the firrst of the top ten technologies that will change the world in the future. However, limited computing, memory, communication capabilities, and especially the severe energy constraints present major challenges for such a vision to become a reality. These unique properties of WSN make traditional mechanisms used in traditional networks can not be applied directly in WSN.WSN can only be deployed after many key technologies to be solved, one of which is security issues. With more and more attention is paid on WSN, its security issues is becoming more important. This thesis analyses the characteristics of WSN and the security issues which is to be solved firstly, then provides the polities according to the threatens confronted with in each layer. The focus is the security threatens of routing layer and specific solution.
