Research On the Key Management Scheme in Wireless Sensor Networks
Ying Wang · Computers & Security · 2009
In this paper, a new group-based node deployment model and a new group-based key management scheme were proposed based on the existed matrix-based key pre-distribution scheme. And the property of the scheme was analyzed in the paper. In the scheme, sensors were deployed in groups, which releases the constraint of equal group size and greatly simplifies the deployment of sensor networks. The knowledge of sensors’ expected locations are not necessary and the probability of pairwise key establishment and security can be increased at the same time.
