A NEW EXTENSIBLE KEY EXCHANGE SCHEME FOR WIRELESS SENSOR NETWORKS
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2014, Vol 2, Issue 11
Abstract
A sensor network is confident of a large number of sensor nodes Sensor nodes are small, low-cost, low-power devices that have following performance communicate on short distances sense environmental data perform limited data processing The network usually also contains “sink†node which connects it to the outside world. Advances in technology introduce new application areas for sensor networks. Foreseeable wide deployment of mission critical sensor networks creates concerns on security issues. Security of large scale slowly deployed and infrastructure-less wireless networks of resource limited sensor nodes requires efficient key distribution and management mechanisms. We consider distributed and hierarchical wireless sensor networks where unjust, multicast and broadcast type of communications can take place. We evaluate deterministic, probabilistic and hybrid type of key predistribution and dynamic key generation algorithms for distributing combination and network-wise keys.
