摘要

A wireless sensor network (WSN) consists of large number of sensor nodes that has limited power resources, computation and communication distributed in a designed area without any fixed structure. Wireless sensor networks are used in applications involving high security such as border security, military target tracking and scientific research which are in dangerous environment. The networks must also guard against adversaries who could capture sensor nodes, intercept transmitted messages, and propagate fake messages to the networks and this is realized by the use of the key distribution scheme. We propose a key distribution scheme using an asymmetric key cryptography where in part of the cryptographic transformation is embedded in hardware i.e. in sensor node and part of it can be done in software. This will reduce the computation on the node without compromising on security. Apart from this we also propose a multi sink network to cope with scalability of network.
