Preserving Privacy in Wireless Sensor Networks using Onion Routing

Abstract

In the era of technology, Internet Of Things (IoT) which is a computing concept connecting a growing range of physical devices across the Internet, enriched our lives. IoT emerges with widespread applications and technologies including Wireless Sensor Networks (WSNs). Over the past few years, WSNs become one of the most evolving technologies and are considered as the connection between physical and virtual worlds for the ability to measure, collect and monitor environmental or physical conditions. Due to the large scale of WSNs being deployed to the Internet, security and privacy risks become crucial. The objective of this paper is to find a technique for anonymous communication and implement a security system for WSNs. This is achieved by implementing “Onion Routing” functionality on sensing devices, utilizing cryptography techniques and key distribution algorithms.
