Study on key distribution scheme for wireless sensor networks

For solving the issue of key distribution in the clustered sensor networks, proposed a key distribution scheme based on layers, in which base station sends the secret knowledge of member nodes to the cluster-header, and member nodes establish pairwise key with their neighbor nodes via cluster-header. The members of clusters don´t need to store a `key pool´ in the process of pre-distribution. The results of analysis show that the proposed scheme has good security and anti-capture.
