Key distribution protocol is a fundamental security service in sensor networks.In this paper,we propose a key distribution protocol integrating 3-dismension grid model with multiple hash algorithm.This protocol,which not only has the advantage of high security performance and low overhead,but also can substantially improve network connectivity,is very suitable for wireless sensor networks in which the nodes are resource-constrained and the network topology changes highly.
