Abstract

Information technology finds its wide application in many fields like healthcare, border security etc. where security of information is very important. With advancement in wireless sensor networks, gathering and processing of data have become much easier and affordable, due to its wide application, providing security to data is required. This work proposes a prototype that uses Raspberry Pi as secure sensor node that performs both regular encryption and XML encryption to provide security to the data collected by sensor nodes and transmit it to the master node in the WSN. The design uses a temperature sensor which can be replaced by any other sensor going forward and can be used in the field of healthcare, border security, and many other areas. The data are collected, processed, encrypted, and wirelessly communicated to the master node. Since there is direct interfacing between the sensor and Raspberry Pi, there is no risk of data loss. The idea of this paper is to meet the goal of comparing the two encryption techniques in terms of processing time and number of characters and to see which is better in terms of both the parameters.

Keywords: Wireless Sensor Networks, Temperaturesensor, Raspberry Pi, XML Encryption
