Encryption of Data Transmitted Through Structure-free Wireless Sensor Networks

Abstract

AbstractRecently, the technology has been developed and wireless networks have received greatinterest in drawing the world's attention to the family. Wireless sensor networks are a set of sensornodes specific resources that collaboratively working on the transfer or follow differentphenomena(Chemical and physical) such as (sound, heat ... etc) and then transmit the informationmonitored wirelessly by connecting sensor nodes with each other until they reach the base station.There are two types of building mechanisms for wireless sensor network (WSN);structure-based andstructure-free. The first is suffering from many problems which can be overcome when dealing withthe other type. Most of the environments that deal with wireless sensor networks are difficult toreach and dangerous. Therefore, they are subject to many security breaches. These violations canlead to severe consequences and difficult to deal with in case they occur. Therefore, security must beprovided through the network in one way or another taking into account that achieving securitythrough the network is not easy because of the resources identified, especially as the security is themain issue and the first in many applications.In this paper, the structure-free typeis applied and in order to achieve security, data transmittedthrough the network is encrypted using the Elliptic Curves Diffie-Hellman(ECDH) and the Rivest-Shamir-Adleman(RSA) algorithms.Simulation results demonstrate that the power consumption of thestructure-free wireless sensor network with data encrypted by ECDH and RSAalgorithms.The resultsshow that the power consumption by ECDH algorithm is better that RSA type with nearly 13%.
