Recently, wireless sensor networks (WSNs) have received much attention by researchers because of their lower cost of deployment and easier to use. These networks are more vulnerable towards security attacks due to the lack of centralized management. The packet drop attack is one of the significant attacks that involve dropping of packets due to malicious compromised node. Different methods are proposed for detection of packet drop attack in WSNs, but these techniques are not providing the feasibility to isolate or stop these attacks’ occurrence. The important mechanism is the reputation systems’ utilization for WSNs. Each node allocates with reputation that determines with a node behaviour using a reputation system. The trustworthy nodes’ have been detected using these reputation systems to perform data forwarding process. However, the effective way to monitor the data forwarding behaviour of a node is the nodes’ monitoring in a promiscuous mode. A new intrusion detection system was proposed in this paper as a methodology of certificate revocation for effective operation and distribution of keys among nodes. The malicious nodes’ keys have been revoked with the introduction of a certificate revocation method. As the malicious nodes are not having valid keys, they couldn’t contact to the remaining nodes. The proposed mechanism simulates using the Network Simulator-2 for different scenarios that enhances network security by comparing with other traditional security algorithms.
