concealed data aggregation in wireless sensor network:a hierarchical method

wireless sensor networks WSN consists of many sensor nodes that are placed on unattended environments such as military sites in order to collect important information implementing a secure protocol that can prevent forwarding forged data and modifying content of aggregated data and has low delay and overhead o fcommunication, computing and storage is very important this paper presents a new protocol for concealed data aggregation CDA inthis protocol the network is divided to virtual cells nodes within each cell produce a shared key to send and receive of concealed data with each other considering to data aggregation in each cell is locally and implementing a secure authentication mechanism data aggregation delay is very low and producing false data in the network by malicious nodes is not possible.
