An one-way function based framework for pairwise key establishment in sensor networks
We develop a one-way function based key establishment framework for Wireless Sensor Networks (WSNs). The proposed framework allows sensors to establish pairwise session keys at an arbitrary network operation stage using pre-loaded one-way functions. We also present an efficient instantiation of the proposed framework using Cellular Automata (CA). The analysis based on the CA instantiation indicates that our framework possesses a number of nice properties: • inherent support for rekeying; • quasi-perfect resilience against node compromise; • computational efficiency; • strong cryptographic strength of generated pairwise keys; • a high probability to establish pairwise keys between sensors. © 2008, Inderscience Publishers.
