在充分考虑异构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,利用基于身份的加密算法(Identity-Based Cryptography,IBC),提出了一种异构无线传感器网络密钥管理方案(KMUIBC),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,与现有的一些典型方案进行了分析比较,结果表明,KMUIBC有较好的性能。
According to the characteristics of Heterogeneous Wireless Sensor Networks(HWSNs) and the defects in current key management schemes,a key management scheme using Identity-Based Cryptography(KMUIBC) is presented.Then,the scheme is analyzed from security,key connectivity,scalability and efficiency.Compared with some current popular schemes, KMUIBC achieves better performance.
