Abstract
With the rapid development of the Internet of Things, numerous security and trust risks, including a single point of failure for authorities, data tampering, unauthorized users decrypting data, and challenges with searching encrypted data, have emerged on the centralized Internet of Things data sharing platform. As a novel technology, blockchain offers the benefits of decentralization, tamper-proofing, and trusted data sharing. Therefore, this article suggests a blockchain-based searchable encryption access control method. Users can simply search the necessary data using keywords provided they comply with the access rules. To ensure the privacy of the data, the cloud will not get any privacy-related information. The simulation demonstrate that our study has a lower time overhead than the current investigations. Data encryption takes 33% less time than standard access control methods, decryption takes 5% less time, and searching takes 75% less time.
