摘要：Wireless sensor network is a collection of large number of low cost resource constraint sensor nodes that communicates using wireless medium. Sensor nodes are resource constrained in memory, sensing, communication capability, and battery power. Data comm u nication between nodes consumes a large portion of the total energy c onsumption of the WSNs. One of the solutions to reduce number of bits transmitted during communication is data aggregation. As wireless sensor networks are usually deployed in remote and hostile environments to transmit sensitive information, sensor nodes are prone to attacks. Collusion attack also main constraint which has to be considered while transmitting a secure data. Thus, security is an important criterion to be considered in WSNs. Many secure data aggregation protocols have been proposed in wireles s sensor networks. In this project, we are using key distribution technique to aggregate and to maintain the secrecy of data. We pro pose a Source privacy based based on elliptic curve cryptography ( SP - ECC). While enabling intermediate nodes authentication, our proposed scheme allows any node to transmit an unlimited number of messages without suffering the threshold problem
