A Cluster-Based Random Key Revocation Protocol for Wireless Sensor Networks

In recent years, several random key pre distribution schemes have been proposed to bootstrap keys for encryption, but the problem of key and node revocation has received relatively little attention. In this paper, based on a random key pre-distribution scheme using clustering, we present a novel random key revocation protocol, which is suitable for large scale networks greatly and removes compromised information efficiently. The revocation protocol can guarantee network security by using less memory consumption and communication load, and combined by centralized and distributed revocation, having virtues of timeliness and veracity for revocation at the same time.
