无线传感器网络安全组网技术研究

随着无线传感器网络(WSN)的高速发展和广泛应用,网络的安全问题越来越受到人们的关注。近几年,在无线传感器网络安全问题上的研究不断取得突破,但大多数研究都关注在数据传输过程中如何保证数据的安全问题,很少涉及到在网络组网过程中如何保证组网的安全问题。在综合分析各种无线传感器网络的安全策略和组网策略的基础上,提出一种无线传感器网络的安全组网技术。无线传感器网络的安全组网技术主要思想是通过在网络的组网阶段加入了消息认证技术和加密技术,拒绝外部非法节点加入网络,使网络的安全性得到更大的提高,在很大程度上降低了WSN遭受外部非法节点攻击的风险,并进一步提高了网络运行过程中的数据安全程度,为无线传感器网络的进一步发展和应用起到了推动作用。

Research on security networking technology of wireless sensor network

Along with the development and widely application of wireless sensor networks （WSN）, its security issues have been attracted more and more interests. Recent years, there are even got some break achievements in the security area, but most of researches are focusing on the data communication security, and seldom of researches are focusing on the security WSN networking. Base on the WSN networking and its security policies, this paper introduces a new WSN security networking technology. In this technology, by application of message authentication and DES technology in the network construction progress, it can reject any illegal nodes joining and can largely reduce outside illegal attack risks. In the meantime, it can provide more enhancements for the data security in the network running and also to improve the WSN application and development.
