In wireless sensor networks, adversaries can easily compromise sensors because the sensor resources are limited. The compromised nodes can inject false data into the network injecting false data attacks. The injecting false data attack has the goal of consuming unnecessary energy in en-route nodes and causing false alarms in a sink. A bandwidth-efficient cooperative authentication scheme detects this attack based on the random graph characteristics of sensor node deployment and a cooperative bit-compressed authentication technique. Although this scheme maintains a high filtering probability and high reliability in the sensor network, it wastes energy in en-route nodes due to a multireport solution. In this paper, our proposed method effectively selects a number of multireports based on the fuzzy rule-based system. We evaluated the performance in terms of the security level and energy savings in the presence of the injecting false data attacks. The experimental results indicate that the proposed method improves the energy efficiency up to 10% while maintaining the same security level as compared to the existing scheme.
