The Key Management Scheme in Clustered Wireless Sensor Network
Gui Yi-hong · Fire Control and Command Control · 2011
In Wireless Sensor Network(WSN),there are two types of security communications: one-to-all and one-to-one.The paper proposes a set of less complexity arithmetics to generate and distribute two types of secret keys.The arithmetics are designed for a clustered hierarchical network.The arithmetics include the initial key management,the periodic key management and the key management upon cluster dynamics.All the communications in the arithmetics are authenticated for using Elliptic Curve Digital Signature scheme.The scheme are evaluationed by simulations.The results indicate clear security and feasibility of our approach in the resource-restricted Wireless Sensor Network.
