摘要：Wireless Sensor Network consists of sensor nodes that are constrained in energy and other resources and is vulnerable to security attacks since the inherent nature of communication is broadcast. In order to reduce the energy consumption it is necessary to optimize the number of packets transmitted. In addition the data has to be encrypted to withstand security attacks. We propose Secure Data Aggregation for Coexisting Queries (SDACQ) in Wireless Sensor Networks that allows parallel coexisting aggregate queries from the sink to be disseminated in an authenticated manner and aggregate the data belonging to coexisting queries into a single packet. The cluster heads aggregate the encrypted data from sensor nodes using additively homomorphic encryption. Thus SDACQ provides secure data aggregation by combining authenticated query propagation with homomorphic encryption at low energy consumption. Simulation results shows that SDACQ provides better performance than other state of the art algorithms.
