Abstract
Key pre-distribution schemes have been proposed as means to overcome Wireless Sensor Networks
constraints such as limited communication and processing power. Two sensor nodes can establish a
secure link with some probability based on the information stored in their memories though it is not
always possible that two sensor nodes may set up a secure link. In this paper, we propose a new
approach that elects trusted common nodes called ”Proxies” which reside on an existing secure path
linking two sensor nodes. These sensor nodes are used to send the generated key which will be divided
into parts (nuggets) according to the number of elected proxies. Our approach has been assessed against
previously developed algorithms and the results show that our algorithm discovers proxies more quickly
which are closer to both end nodes, thus producing shorter path lengths. We have also assessed the
impact of our algorithm on the average time to establish a secure link when the transmitter and receiver
of the sensor nodes are ”ON”. The results show the superiority of our algorithm in this regard. Overall,
the proposed algorithm is well suited for Wireless Sensor Networks.
