Efficient and Secure Data Aggregation Scheme for Wireless Sensor Networks

Data aggregation is an important solution for achieving effective transmission and better power conservation in wireless sensor networks.Many applications require reliable and trustful data aggregation.Aimed at the demand,a new secure data aggregation algorithm is proposed to ensure the confidentiality and integrity of aggregated data.The algorithm uses the blend of end-to-end and hop-by-hop encryption for data transmission,and attestation algorithm to detect the malicious node and forged data.Simulation results show that the proposed algorithm can effectively detect malicious nodes and ensure the accuracy of the aggregation.
