Survey on End-To-End Confidentiality in Wireless Sensor Networks
Journal Title: INTERNATIONAL JOURNAL OF COMPUTER TRENDS & TECHNOLOGY - Year 2014, Vol 8, Issue 2
Abstract
A wireless sensor network (WSN) is a collection of a large number of sensor nodes and few sink nodes that have limited Computation, communication and power resources. Data aggregation is used to reduce amount of data transmission and increases the lifetime of sensors. Data aggregation is the process of combining the raw data from one or more sensor nodes and performs operations as min, max, count, avg. The sensor nodes are often deployed in hostile environment so the aggregated result should be protected from the various types of attacks in order to achieve the data integrity-confidentiality and authentication. The various approaches given for the secure data aggregation is classified into two groups, secure data aggregation on unencrypted data and secure data aggregation on encrypted data. The paper proposes a detailed survey on secure data aggregation on encrypted data.
