Threshold-Based Key Predistribution in Ad hoc Network

To cut down the dependent of key management scheme on resource of networks, this paper deeply researches polynomial-based key predistribution in distribution sensor networks for reference and presents an efficient key predistribution scheme for Ad hoc networks, a threshold-based key predistribution scheme. The analysis in this paper indicates that this scheme has a number of good properties, such as high probability to establish pairwise keys, tolerance of node captures, and low communication overhead.
