A Random Perturbation-Based Scheme for Pairwise Key Establishment in Sensor Networks

This paper proposes a novel random perturbationbased(RPB) scheme. The scheme guaranteesthat any two nodes can directly establish a pairwise keywithout exposing any secret to other nodes. Even after alarge number of nodes have been compromised, the pairwisekeys shared by non-compromised nodes remain highly secure.Moreover, the scheme adapts to changes in networktopolog..
