在网络通信技术不断发展的今天，无线传感网络已日臻完善和成熟，被广泛地应用于社会各行业领域之中，且随着其技术的不断突破，现已同通信技术与计算机技术一道成为我国信息技术的三大支柱产业，在产业进步与经济发展方面扮演着极其重要的角色. 但由于无线传感技术是以大量的静止的或移动的传感器以自组织或者多跳的方式构成的无线网络作为工作的基础，因此很容易受到外部环境的影响而无法正常地工作. 因此，如何设计出一种高效节能且安全系数较高的无线传感网络安全协议成为当今信息技术领域的重要课题，也是难题. 本文试从无线传感网络协议的工作模式以及网络密钥管理的角度出发，阐述基于相邻节点协作的无线传感器网络密钥管理方案的优势并进行安全性分析，希望能实现无线传感网络安全协议的突破.

Nowadays，with the development of network communication technology，the wireless sensor networks has been widely used in various industries and social fields，which is becoming more and more perfect and mature. With the continuous breakthrough of its technology，now it becomes one of the three pillar industries of information technology in China with the communication technology and computer technology，and plays a very important role in the industry progress and economic development. However，the wireless sensor technology is composed of a large number of stationary or moving sensors in the basis of a self - organizing way or multi hop wireless network，so it is easily affected by external environment and can not work normally. Therefore，how to design a high efficiency and saving energy and high safety factor of wireless sensor network security protocol has become an important topic in the field of information technology，and it is also a problem. This paper describes the wireless sensor network adjacent node cooperation advantages and security analysis based on this key management scheme from the perspective of the wireless sensor network protocol working mode and network key management perspective，hoping to achieve a security protocol for wireless sensor network break.
