- W4385550723 abstract "Abstract Nowadays, the adoption of the Internet of Things (IoT) framework in various healthcare industries has grown rapidly in the recent years. The IoT devices generates huge amount of data which are often sensitive, such as personal health information. It is mandatory to ensure that this data is protected from unauthorized access and use. However, the resource-constrained nature of these devices can make it difficult to implement robust security measures, such as encryption and authentication. Blockchain is a promising approach for the secure management of medical record in immutable way. This problem can be resolved with ciphertext-policy attribute-based encryption, which allows granular access control. The local gateways that are directly interfaced to the Ethereum blockchain-based smart contract platform are utilised to create and implement a distributed and dependable user authentication and access control mechanism for smart based healthcare. In this paper, the use of a DBC-based CP-ABE approach offers a secure and decentralized solution for secure communication and data protection, and providing a more secure and trustworthy system. The proposed system is based on the idea of an Elliptical Curve Cryptography (ECC)-based CP-ABE method reduce complexity and provide data security in remote patient monitoring. On the other hand, blockchain-based smart contracts offer a dynamic, optimal, and self-adjusted access control in smart healthcare system. It lowers the overhead associated with conducting resource-intensive authentication procedures and blockchain communications at IoT devices. The result shows the effectiveness of the proposed scheme in terms of computation and processing time as well as its resistance to several security intrusions over existing schemes." @default.
