A New Kind of Dynamic Key Protocol for Wireless Sensor Network

Abstract

For the source limitations and vulnerabilities of the sensor nodes of Wireless Sensor Networks, we propose the new kind of dynamic key protocol for wireless sensor network, using the unidirection of hash function and the thinking of Hill to study the dynamic key matrix. Through theoretical analysis of some aspects, our method can promote security, connectivity expansibility; the results show that this protocol reduces storage space and communication energy consumption also.
