In this paper the authors propose a Bandwidth-Efficient Cooperative AutheNtication (BECAN) scheme for filtering injected false data in wireless sensor networks. Sensor node could be easily compromised as the attacker can gain control obtain key values and change the properties of the node. This results in a false report to sink and energy waste in en-route nodes. The proposed BECAN scheme can save energy by early detecting and filtering the most of injected false data with less time and difficulty at the en-route nodes.
