Design and Implementation of a Secure Internet of Things (IoT) System using Blockchain Technology

Thesis Abstract

Abstract
The rapid growth of the Internet of Things (IoT) technology has led to an increase in the number of connected devices and data exchange, raising concerns about security and privacy. Blockchain technology, known for its decentralized and tamper-resistant nature, has emerged as a promising solution to address these issues. This thesis presents the design and implementation of a secure IoT system using blockchain technology. The research aims to develop a robust and secure framework that ensures data integrity, authenticity, and confidentiality within IoT networks. Chapter One provides an introduction to the research, discussing the background, problem statement, objectives, limitations, scope, significance, structure of the thesis, and definition of terms. The IoT landscape and the need for enhanced security measures are highlighted, setting the stage for the proposed solution. Chapter Two delves into a comprehensive literature review covering ten key aspects related to IoT security, blockchain technology, and their integration. Chapter Three outlines the research methodology employed in this study. It includes detailed descriptions of the research design, data collection methods, system architecture, security protocols, blockchain implementation, and testing procedures. The chapter emphasizes the systematic approach adopted to design and implement a secure IoT system using blockchain technology. Chapter Four presents an in-depth discussion of the findings obtained from the design and implementation process. Various aspects of the secure IoT system, including data encryption, access control, consensus mechanisms, and smart contracts, are analyzed. The chapter also explores the challenges encountered during the development phase and proposes potential solutions for future enhancements. In Chapter Five, the conclusion and summary of the project thesis are provided. The research outcomes, key findings, contributions, and implications are discussed, along with recommendations for further research in the field. The study concludes by emphasizing the importance of integrating blockchain technology into IoT systems to enhance security and trust in connected environments. Overall, this thesis contributes to the growing body of knowledge on securing IoT systems using blockchain technology. The research outcomes provide valuable insights for researchers, practitioners, and policymakers seeking to address the security challenges in the evolving IoT landscape.
