Key Forwarding: A Location-Adaptive Key-Establishment Scheme for Wireless Sensor Networks

In this paper we propose an improved alternative for the path key establishment phase of bootstrapping in a sensor network. Our scheme lets the network adapt to the deployment configuration by secure transmission of predistributed keys. This results in better connectivity than what path key establishment can yield. The communication overhead for our scheme is comparable with that for path key establishment. Moreover, the assurance of good connectivity allows one to start with bigger key pools, thereby improving resilience against node capture.
