N Tier Modeling of Robust Key Management for Secure Data Aggregation in Wireless Sensor Network

Abstract

The recent advancement in the domain of wireless communication and networking has led to newlinea situation where the exponential growth of wireless sensor devices and their connectivity to newlinethe internet is in use. Thereby, increasing demand for data exchange in this open wireless newlinesensor network channel attributes make information transmission, resource constrained and newlineat the same time make it vulnerable to different security attacks. newlineThe existing solutions towards security aspects in WSN are minimal. With the gaining newlinepopularity of WSN based applications, it is critical to study and build security related models, newlinearchitecture and algorithms. The study explores the existing security loopholes in the newlineconventional routing and network operations especially for a large scale WSN that are more newlinevulnerable to the intruders or attackers. The critical investigational study reveals that the newlinetraditional security approaches for WSN having various design challenges from the newlineviewpoint of computational complexities. In the large scale WSN, the traditional security newlinesolutions degrade the network performance and QoS. The approach of lightweight newlinecryptographic algorithms is gaining popularity to meet the futuristic security and QoS goals newlinefor WSN based Internet-of-Things (IoT) applications. Hence, the prime purpose of this newlineresearch study is to formulate a robust security solution which can ensure a higher degree of newlinedata privacy concerning integrity, authentication, and validation and at the same time do not newlineaffect the communication performance from the QoS aspects. newlineFinally, the study frames its design objective, where addressing this problem it comes newlineup with two different novel solutions. Firstly, a cost-effective solution and its conceptual newlinedesign and modeling namely Request Authentication using Shared Key (RASK), followed by newlineanother approach namely Framework for Secure Data Aggregation (FSDA). However, the newlineoverall thesis presented in a way where initially it discusses the preliminary and background newlinestudy associated wi
