Survey on Data Security in Wireless Sensor Networks

Abstract

Wireless Sensor Networks (WSNs) consist of hundreds and thousands of sensor nodes often deployed in an unsecured or in hostile
environment. WSNs are used in wide variety of applications such as military, industrial processing, health monitoring areas. The areas include
serving of sensitive information. WSNs have many constraints such as physical capture, energy resource consumption, low capacity etc. These
constraints make security a challenge. In this paper we present a survey on WSNs, we define how the data can be organized, attacks, security
objectives and what are mechanisms to deal with the security objectives.

Keywords: Wireless Sensor Networks, Data Security, Data Authentication, Data Confidentiality, Data Availability.
