摘 要:在当前信息发展飞速的时代,无线传感器网络作为一种新型的应用型网络,已经在很多领域得到了广泛应用。安全问题成为制约无线传感器网络发展的关键。在阐述目前无线传感器网络的自身特点以及安全需求的基础上,重点介绍了安全框架协议SPINS,针对子协议SNEP本身存在的不足提出了相应的改进方案。通过分析可知,该方案可降低基站依赖性、防范DoS攻击,并且对基站的计算、存储需求降低,网络内节点计算与存储开销没有明显增加,可扩展性好。In the rapid development of the information era,and as a new type of application-oriented network,wireless sensor network has been widely used in many fields.Security has become the key problem that restricts the development of wireless sensor networks.Based on the characteristics and security requirements of the wireless sensor network,the security framework protocol SPINS is introduced.Considering the deficiency of its sub-protocol SNEP,an improved scheme is put forwarded.Through the analysis,it can be known that the scheme can reduce the base station dependency,prevent DoS attack,and reduce the calculation and storage requirements of the base station.While the calculation and storage cost of the nodes in the network are not significantly increased,and the scalability is good.
