Analyzing Blockchain Technology for Enhancing Security in Smart Home Systems: Current Developments and Future Directions

The Internet of Things (IoT) holds a great potential in revolutionizing the development of intelligent home environments. The Internet of Things is seamlessly integrated into our everyday routines, especially in modern smart homes, where it aids in streamlining resource management, enabling convenient remote control, and facilitating pervasive sensing. The use of smart home technology presents a significant challenge due to the range of issues it can cause, including concerns about transparency, security and privacy. The main reason for this is that devices are often used in open networks that may be susceptible to security breaches, due to inadequate device authentication methods, inefficient secure data storage and access procedures, and exposure to various threats. Blockchain shows great potential as a technology that can effectively tackle these challenges and fulfill the necessary criteria. This research study introduces a hybrid blockchain architecture, dynamic key management techniques, cross-domain authentication and lightweight cryptographic solutions to address critical IoT constraints, including security, scalability, latency, interoperability and energy efficiency, providing a unique contribution to advancing smart home security frameworks. In this paper, we studied and analyzed the various research works already done and provided a comprehensive review of current advancements, highlighted the major progress and discussed open challenges for future research directions.
