A Survey on Key Distribution Schemes in Wireless Sensor Networks

Abstract

Abstract-in this paper, we propose the criteria and classifications of key management schemes in wireless sensor networks, and provide a survey on the key distribution management schemes including basic key pre-distribution schemes, polynomial based key distribution schemes, location based key distribution schemes and key management in hierarchy networks, and make a discuss and analysis of different key management schemes. Finally, we indicate the new research directions of key management schemes in wireless sensor networks.
