Revocation and Self Healing of Keys in Hierarchical Wireless Sensor Network
In this paper, the authors have discussed a key distribution scheme with revocation and self healing mechanism. Self healing key distribution scheme enables a group of users to establish a group of keys over an unreliable network. In their scheme cluster header distributes session keys to the group nodes for communication. The concept of key distribution scheme with revocation was first mooted by Staddon, since then there have been many improvements in the scheme. They have given a scheme in this paper which removes all the flaws of earlier researches and it is more secure and authenticate.
