The study on key distribution and management mechanisms in Wireless Sensor Networks

A Wireless Sensor Network (WSN) is constructed by a group of sensor nodes with characteristics of tiny shape, low-energy consumption and cheap cost. In general, sensor nodes are distributed in a certain area. In this paper, we find the root of a finite field polynomial to achieve the implicit security. We partition the key and distribute to the nodes of network. We can use these key partitions to revert to the original key.
