On Secure Communication in Sensor Networks Under <i>q</i>-Composite Key Predistribution With Unreliable Links

Topological Properties of Wireless Sensor Networks Under the Q-Composite Key Predistribution Scheme With Unreliable Links (CMU-CyLab-14-002)

The seminal q-composite key predistribution scheme[3] (IEEE S&P; 2003) is used prevalently for secure communica-tions in large-scale wireless sensor networks (WSNs). Yağan [12](IEEE IT 2012) and we [15] (IEEE ISIT 2013) explore topologicalproperties of WSNs employing the q-composite scheme in thecase of q = 1 with unreliable communication links modeledas independent on/of...

Review on Key Predistribution Schemes in Wireless Sensor Networks

A wireless sensor network consist distributed sensors which are used to monitor physical or environmental conditions like temperature, sound, pressure and so on. Wireless sensor network are used in future in many applications like military, investigation teams, researches and so on. Security is the main issue in wireless sensor network. Sensor network arrange several types of data packets, pack...

Key Predistribution Schemes for Distributed Sensor Networks

Key predistribution schemes for distributed sensor networks have received significant attention in the recent literature. In this paper we propose a new construction method for these schemes based on combinations of duals of standard block designs. Our method is a broad spectrum one which works for any intersection threshold. By varying the initial designs, we can generate various schemes and t...

Random Key Predistribution Schemes for Sensor Networks

Key establishment in sensor networks is a challenging problem because asymmetric key cryptosystems are unsuitable for use in resource constrained sensor nodes, and also because the nodes could be physically compromised by an adversary. We present three new mechanisms for key establishment using the framework of pre-distributing a random set of keys to each node. First, in the q-composite keys s...
