Secure Smart Home Systems: A Blockchain Perspective

The unprecedented growth of the smart home industry brings increasing amount of IoT devices into people's home. The transmission of data and execution of commands across connected network were meant to bring security, comfort and accessibility. However, the inter-connectivity and complexity of smart home systems leads to higher vulnerability to cyberattacks, network congestion and information leaks. In this paper, we first analyze the limitations of existing centralized approaches. Then we propose a blockchain-enabled solution to help build a secure smart home system. We demonstrate the design architecture and implementation methods as a proof of concept. We believe that the proposed blockchain-enabled solution can improve security while offering intelligent control of smart home systems.
