Blockchain-Based Smart Home Gateway using Secure Chaotic Hash Function

There are a number of issues that existing authentication systems face in a smart community. These include insufficient authentication efficiency, an inflexible authentication methodology, and an unsecured data exchange server. The dependability and security of the proposed blockchain-based smart home strategy were extensively tested for confidentiality, integrity, and privacy, as well as other factors. In terms of the parameters of classic centralized architecture, blockchain technology is being used in the data storage and exchange blocks. To ensure data integrity both inside and outside of the smart home network, it is necessary to ensure that all users present in the network are authenticated. The network under consideration is built on the Ethereum platform. The performance measures to be considered were accuracy, security, and response time. The experimental results reveal that our proposed technique outperforms currently available techniques in terms of overall performance. In particular, when compared to other state-of-the-art systems, our proposed system has the highest accuracy of 96% and generates a stronger output in the second stage when compared to centralized architecture with an accuracy of 71%, representing a 25% difference in terms of improving the accuracy of smart homes.
