Data aggregation is an important feature in Wireless Sensor Networks (WSN), where data inputs at an aggregator node are merged to produce compact small output data, thus reducing the network's transmission overhead and preserving the scarce-battery resources of sensors. Unfortunately, if not secured against attackers, data aggregation can produce erroneous results, which can induce the network operator to take wrong decisions. In this paper, the authors present a secure aggregation protocol for cluster-based WSN, which is adapted to a large variety of aggregation functions, and which does not rely on trusted aggregator nodes.
