1. A method of performing a distributed verification with respect to measurement data in a sensor network as embodied by a computer, the method comprising:

  • verifying, by an aggregator, the measurement data received from each of a plurality of sensors;

    generating, by the aggregator, verification request data using the verified measurement data;

    transmitting the verification request data to a verifier;

    verifying, by the verifier, the aggregator via a predetermined number of sensors out of the plurality of sensors and the verification request data;

    transmitting, by the aggregator, an aggregation result with respect to the measurement data to a base station when the aggregator is verified; and

    verifying, by the base station, the aggregation result,wherein the transmitting of the aggregation result comprises;

    generating a MAC with respect to the measurement data using a key shared between the aggregator and the base station;

    calculating a verification value using a signature received from the verifier and a predetermined calculation method with respect to the MAC;

    generating the aggregation result including the measurement data and the verification value; and

    transmitting the aggregation result to the base station.
