Abstract

Recently, Dutta et al. [1] proposes a constant storage self-healing key distribution with revocation in wireless sensor network. The advantage of [1] is that it requires constant storage of personal keys for each user. In this paper, we show that Dutta's scheme is insecure against the proposed attack, whereby users can access any other's secret keys and session keys which they should not know according to Dutta's scheme. Moreover, we proposed two kinds of improved schemes which are resistant to this kind of attack. The first scheme is unconditional secure and we analyze it in the security framework of [1]. The second scheme is in the model of computational secure. In the end, we analyze the second scheme and show that it is a self-healing key distribution scheme with revocation and achieves both forward and backward secrecy.
