摘要
无线传感器网络(Wireless Sensor Networks,WSN)是由资源有限的传感器节点构成的无线网络,由于其本身资源方面存在的局限性和脆弱性,使其安全问题成为一大挑战。密钥管理作为安全机制的重要环节,始终是无线传感器网络安全领域的研究热点。本文在研究无线传感器网络安全问题的基础上,对具有代表性的密钥管理方案进行了深入研究,全面分析其利弊以及适应性问题,最后提出了进一步的研究设想。
Wireless Sensor Networks（WSN） are wireless networks that include sensor nodes with limited resources.Due to its source limitations and vulnerabilities,WSN security problem has become a great challenge.As the key link of security mechanism,key management is always the focus in security field of WSN.Through researching on WSN security problem,typical key management schemes were further researched and their advantages and disadvantage were described as well as their applicability.Finally,the future studying directions were pointed out.
