Abstract

With the gradual improvement of people's demand for quality of life, the smart home industry is developing rapidly. A large number of smart home devices concentrate a large amount of data, so smart home systems mostly use data cloud outsourcing to manage data. Meanwhile, the centralized cloud servers used by traditional smart home solutions bring single-point failure problems and data privacy protection risks. To solve the above issues, we propose a blockchain-based public audit solution for smart home data integrity. The scheme uses blockchain and IPFS instead of centralized cloud servers, and supports dynamic attributes of data in cloud servers. Further, we extend the bulk auditing functionality. Finally, the security analysis and performance analysis show that our scheme outperforms existing scheme, and the audit computation overhead is reduced by 38%. When the number of users of the batch audit function is greater than 10, the average audit computation overhead per user is significantly reduced, which can effectively improve audit efficiency.
