Wireless Sensor Networks (WSNs) rely on aggregation for efficiency, however, this bring some security hidden trouble. This paper presents a Black Box Inspection Aggregation (BBIA) protocol that ensures security and reliability of aggregated data in the presence of compromised sensor nodes. Cluster heads validate the cluster members' aggregation result and they also need no less than threshold amount evidence from the cluster member to proof themselves credible at the same time. To ensure the efficient of our protocol, only Message Authentication Code (MAC), and XOR operation are employed. Hence, BBIA has an acceptable transmission overhead in addition to security performance.
