Cluster-based Pre-distribution Key Mechanism for Wireless Sensor Network

In order to overcome the shortcomings of connectivity and resilience,which are poor in most other key pre-distribution mechanism for Wireless Sensor Network(WSN),this paper proposes a mechanism for cluster-based networks.The mechanism makes use of the distributed management strategy and can isolate the compromised sensors from the networks instantaneously through updating the coefficients of the shared-polynomial and preventing all other sensors from establishing pairwise keys with compromised sensors as a result.Experimental results show that this mechanism has good ability to resist capture and scalability.Furthermore,the updating of the key pair in time guarantees the continuing high connectivity of the networks.Besides,the communication overhead of the base station can not increase enormously when execute revocation mechanism operating.
