Abstract

In this paper, we analyze an existing constant storage self-healing key distribution scheme in wireless sensor networks. Then, we show two attacks and propose a modified scheme to overcome the two flaws. At last, we propose a new self-healing key distribution scheme to improve the modified scheme. The most prominent properties of the new proposed scheme are as follows: achieving forward and backward secrecy and resisting to a collusion attack. So that a revoked user with the assistance of the newly joined users cannot get any information of group session keys which it is not entitled to get.
