Secure-SPIN: Secure sensor protocol for information via negotiation for wireless sensor networks

Many routing protocols have been proposed for sensor network, but most of them have not designed with security as a goal. Sensor protocol for information via negotiation (SPIN) protocol is a basic data centric routing protocol of sensor networks. In this paper, we present the design of secure-SPIN, a secure extension for the SPIN protocol. We divide secure-SPIN into three phases and use some cryptographic functions that require small memory and processing power to create an efficient, practical protocol. Then we give security analyses of this protocol. It shows that this secure protocol may increase the data communication security in wireless sensor networks.
