Title: "A Survey on Secure Data Aggregation in Wireless Sensor Networks"

by

Mr. Saiyu Qi


Abstract:

Wireless sensor networks (WSNs) have been rapidly deployed for various
applications such as object tracking, health monitoring, navigation and
military surveillance. In such applications, the WSN often plays a role of
transmitter to transfer data readings from the sensory area so that the
network manager or professional user can deduce physical knowledge from
these readings. One of the most important transmission manners is data
aggregation. The data aggregation technique can reduce the communication
overhead of sensors as large numbers of data readings can be aggregated
into smaller ones in-network. The successful deployment of data
aggregation however, suffers from secure threats. As sensors are often
deployed in open or hostile environment, an adversary can easily launch
various attacks to steal the private data or prevent the legal users to
get the correct result. In this survey, we investigate the existing secure
data aggregation schemes and classify them into different categories based
on their secure goals. We analyze the advantages and disadvantages of the
schemes in each category and conduct thoroughly comparison. The comparison
result contributes a deep view to the current research progress. We also
discuss the open issues in this area and point out the future directions.
