Title: A Key Management Scheme for Wireless 
Sensor Networks Using Deployment Knowledge

To achieve security in wireless sensor networks, the messages sent among 
sensor nodes have to be encrypted.  The keys for encryption purpose must
be agreed upon by the sensor nodes. However, key agreement is not
trivial in sensor networks. Many existing key agreement schemes are not
suitable for sensor networks.  In this paper, the authors
propose a key pre-distribution scheme that exploits the 
deployment knowledge.  This scheme increase the connectivity of the 
networks  without sacrificing the security against node capture
attack.  The performance of this scheme is evaluated
theoretivcally and empirically.
