Secure Data Transfer using Cryptography with Virtual Energy for Wireless Sensor Network
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2013, Vol 4, Issue 8
Abstract
The wireless sensor network technology is one of the largest data processing and communication networks systems which continuously developed for distributed environment in field of real time application. There are so many factor associated with it’s as Data security, operating speed, cost efficiency and additional sensor network constraints. Main consideration is about increase the security over existing attacks without affect the performance and complexity of overall wireless sensor network. Normally, two approach of symmetric key and asymmetric key data encryption technique is applied for it at sensor nodes. So, the proposed work is to explore design of cost efficient secure network protocol which reduces number of key transmission required in symmetric key encryption for rekeying task. In proposed algorithm mainly three steps are performed as key generation, data cryptography and data transmission. First generation of key is done by method of dynamic key approach using virtual energy value of sensor node. Then mechanism of symmetric key block cipher algorithm RC5 is performed for data cryptography. After that encrypted data packet transferred over the network using TCP/IP protocol layer in WSN. It also has performance evaluation to achieved benefit of lightweight symmetric key block cipher algorithm for proposed work in unreliable medium of wireless sensor network.
