Key management is an important cryptographic primitive upon which other security services are built. Most of the existent pairwise key management protocols consider homogenous ad hoc sensor networks. However, recent researches have demonstrated the limitation of this architecture in terms of performance and scalability. Therefore, this paper focuses on proposing a pairwise key management protocol...
In this work, to obtain stronger connectivity, we propose and analyze a scheme extended by random key pre-distribution (RKP), which can work only in highly dense networks and require path construction. We investigate the threshold property of multi-hop key connectivity in random geometric networks. We have made use of the Jansonpsilas inequality to deal with the dependency overhead. Accordingly, our...
