A Scheme for Key Revocation in Wireless Sensor Networks
Key revocation is a challenging task in wireless sensor networks. There can be many nodes in a sensor network sharing the same key(s) in their key ring. If any of those nodes in the network gets compromised then the keys of those nodes having same keys will also be revealed. Nodes sharing keys with the compromised node should revoke the shared keys as soon as possible. In this paper, the authors proposed key revocation scheme based on voting procedure. They have shown that all the keys of a compromised node can be successfully revoked from the entire network.
