This paper presented a key management scheme for wireless sensor networks based on polynomial computing and group designing.The scheme used polynomial computing to generate node-to-node pair-wise keys to enhance the security of network.Introduced a grouping scheme to improve the network connectivity of polynomial computing.Meanwhile,designed a new grouping pattern to partition the ID of a node into group ID and intra-group node ID,which could enlarge the maximum supportable network size by extending the node ID.Results show that this key management scheme achieves a nice tradeoff between the network security,connectivity and overheads.
