Towards $k$-connectivity of the random graph induced by a pairwise key predistribution scheme with unreliable links
We study the secure and reliable connectivity of wireless sensor networks. Security is assumed to be ensured by the random pairwise key predistribution scheme of Chan, Perrig, and Song, and unreliable wireless links are represented by independent on/off channels. Modeling the network by an intersection of a random K-out graph and an Erdős-Rényi graph, we present scaling conditions (on the numbe...
متن کاملOn the scalability of the random pairwise key predistribution scheme: Gradual deployment and key ring sizes
The pairwise key distribution scheme of Chan et al. is a randomized key predistribution scheme which enables cryptographic protection in wireless sensor networks (WSNs). Although this pairwise scheme has several advantages over other randomized key predistribution schemes, including the original scheme of Eschenauer and Gligor, it has been deemed non-scalable for the following two reasons: (i) ...
متن کاملAn Efficient Pairwise Key Predistribution Scheme for Wireless Sensor Networks
Key management plays fundamental role in research on security service in wireless sensor networks (WSNs). However, due to the resource constraints, establishing pairwise keys in WSNs is not a trivial tasks. Several exiting key management schemes have been proposed in literature to establish pairwise keys between sensor nodes, but they either can not offer strong resilience against node capture ...
متن کاملTopological 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...
متن کاملNon-Interactive Hierarchical Pairwise Key Predistribution Scheme with Multi-Level Key Establishment
Networking environments with connectivity, bandwidth and computational constraints such as critical infrastructure networks or MANETs benefit from non-interactive key predistribution capabilities. In these networks, nodes can compute shared keys using public identities without the need for interactions once basic key materials are distributed to them. Motivated by the electric power grid, in th...
