Efficient key management in sensor networks
Abhishek Parakh, Subhash C. Kak · 2010
We present an efficient key distribution scheme for sensor networks in which resource constraints and the possibility of node capture and malfunctions are considered. We deal with the problem of efficient routing and key distribution simultaneously. The resulting scheme is scalable and resilient to node captures and malfunctions. Under certain assumptions, the scheme has an upper bound of log2N on the diameter of the network and the number of keys required per node (where N is the number of nodes in the network).
