Abstract
Data aggregation in wireless sensor networks (WSN) is a rapidly emerging research area.It can greatly help conserve the scarce energy resources by eliminating redundant data thus achievinga longer network lifetime. However, securing data aggregation in WSN is made even morechallenging by the fact that the sensor nodes and aggregators deployed in hostile environments areexposed to various security threats. In this paper we survey the current research related to security indata aggregation in wireless sensor networks. We have classified the security schemes studied in twomain categories: cryptographic based scheme and trust based scheme. We provide an overview and acomparative study of these schemes and highlight the future research directions to address the flawsin existing schemes
