在充分考虑无线传感器网络自身特点的基础上,针对现有无线传感器网络密钥管理中存在的问题,利用Blom矩阵,提出了一个基于部署信息的无线传感器网络密钥管理方案(KPSBM),并从该方案的安全性、连通性、可扩展性、有效性等方面进行分析,并与现有的一些常用方案进行了分析比较,结果表明,KPSBM在这些方面有较好的性能。
According to the characteristics of Wireless Sensor Networks (WSN) and the defects in current key management schemes,a key management scheme(KPSBM) based on deployment knowledge is presented using Blom matrix.Then,the scheme is analyzed from security,key connecfivity,scalability and efficiency.Compared with some current popular schemes,KPSBM achieves better performance.
