Abstract

Problem statement: Wireless sensor networks, brings out variety of different challenges at energy level, integrity, authentication, communication cost. Approach: In the secure data aggregation techniques, reduction in the energy consumption was not elaborated in detail, since aggregator means of connection to sink was either direct or through other aggregators which need high energy level. Results: We suggest an Energy Constrained Secure Hierarchical Data Aggregation in Wireless Sensor Networks. At first the network was divided into clusters, each cluster begins with an aggregator and aggregator was connected to sink. Based on distance to sensor nodes and its energy level the aggregator detects the node. Separate keys were distributed to the two levels i.e., sensor node to the aggregator and aggregator to the sink. Whenever a data had to be sent from a sensor node to another node; initially the sensor node encrypts the data using a key and sends it to the aggregator. Conclusion/Recommendations: The digital signature algorithm that is based on the Elliptic Curve Digital Signature Algorithm is as secure and has reduced energy consumption.
