【摘要】 无线传感器网络(Wireless Sensor Network,WSN)具有信息收集能力强、信息收集速度快、准确率高等特点,可以适应各种环境,尤其是可以监测人类无法到达或极难到达的区域。数据安全是无线传感器技术研究的一个重要内容。无线传感器网络分布范围广,采用多跳通信方式,通行信号暴露在网络中,网络容易受到窃听、哄骗、注入、重放等多种方式的攻击。本文提出一种基于身份认证和传输加密的WSN安全机制,能够有效地分辨网络节点的身份,建立安全的网络基础,同时采用加密方式进行传输,将认证和加密结合起来保护网络的安全,适合使用在复杂环境下的无线传感器网络,体现出了网络优越的性能更多还原

【Abstract】 Wireless sensor network with the characteristic of high capability of information collection,high speed to collect information and high accuracy,can be adapt to the environment,specially can detect the area the human can not arrive or extremely difficult to reach.Data security is one research of the wireless sensor network of important content of the wireless sensor network research.Wireless sensor network can distribute a large range,adopt the jump communication mode.Communication signal is uncover in the network,be vulnerable to eavesdropping,coaxing,injection,replay-attack and so on.This paper put forward a kind of WSN secure transmission mechanism based on nodes authentication and data encryption.To build a security network foundation and using encryption to transmit at the same time,it combine the authentication and encryption to protect the safety of network,it suitable for use in the complex environment of wireless sensor network(WSN) and reflects the performance of the network is superior更多还原
