Constant Storage Self-Healing Key Distribution with Revocation in Wireless Sensor Network

— A self-healing key distribution scheme enables a large group of users (sensor nodes) to establish a session key dynamically over an unreliable, or lossy wireless network. The main property of self-healing ensures that the qualified users can recover the lost session keys on their own from the broadcast packets and some private information, without any additional communication with the group manager, thus decreasing the load on the group manager. The only requirement for a user to recover the lost session keys, is its membership in the group both before and after the sessions in which the broadcast packets containing the keys are sent. Self-healing approach of key distribution is stateless in the sense that a user who has been off-line for some period is able to recover the lost session keys immediately after coming back on-line. This paper presents a new selfhealing key distribution scheme with revocation capability that requires constant storage of personal keys for each user and...
