基于CPK的安全分簇方案

A Secure Clustering Scheme Based on CPK

传感器网络中,基于分簇的拓扑结构可以均衡网络中的能量消耗、延长网络的寿命、提高管理效能、增强可量测性,适合于大规模部署应用。CPK(Combined Public Key)算法密钥后台脱线产生、不需要第三方的验证、存储要求低、通信开销小。通过将CPK算法引入分簇过程,安全技术前移,实现安全分簇可以有效增强网络安全性并且减少不必要的能量消耗,对于传感器网络的实际应用有着重要意义。

Clustered topology is suitable for large scale deployment application of sensor networks, because it is an effective mechanism to balance the energy consumption in network, extend network life time, enhance the management efficiency and improve network scalability. CPK （Combined Public Key） algorithm produces public/private keys offline, and it doesn＇t need the identity authentication of the trusted third party. CPK algorithm is introduced into the clustering process to effectively strengthen the network security and drastically reduce the unnecessary energy consumption. The new algorithm is of great value for the application of WSN.
