The document proposes a Cluster-based Certificate Revocation with Vindication Capability (CCRVC) scheme for mobile ad hoc networks. The scheme aims to isolate attackers from participating in the network by revoking their certificates. It recovers warned nodes to participate in the revocation process and proposes a threshold-based mechanism to assess if warned nodes should be vindicated as legitimate. Extensive simulation results demonstrate the proposed certificate revocation scheme is effective and efficient at guaranteeing secure communications in mobile ad hoc networks.
