SHA-256 Hardware Proposal for IoT Devices in the Blockchain Context

Sensors, Journal Year: 2024, Volume and Issue: 24(12), P. 3908 - 3908

Published: June 17, 2024

This work proposes an implementation of the SHA-256, most common blockchain hash algorithm, on a field-programmable gate array (FPGA) to improve processing capacity and power saving in Internet Things (IoT) devices solve security privacy issues. presents different approach than other papers literature, using clustered cores executing SHA-256 algorithm parallel. Details about proposed architecture analysis resources used by FPGA are presented. The achieved throughput approximately 1.4 Gbps for 16 single FPGA. Furthermore, it saved dynamic power, almost 1000 times less compared previous works making this proposal suitable practical problems IoT environments. target was Xilinx Virtex 6 xc6vlx240t-1ff1156.

HierChain: A Hierarchical-Blockchain-Based Data Management System for Smart Healthcare

IEEE Internet of Things Journal, Journal Year: 2023, Volume and Issue: 11(2), P. 2924 - 2934

Published: July 17, 2023

Healthcare is a crucial element of human lives that produces substantial amount medical data every year. A major difficulty faced by e-Health systems the secure storage and sharing this without compromising its integrity privacy. Being trustless, traceable, immutable technology, blockchain has potential to address these issues. In paper, we propose HierChain, hierarchical blockchain-based system for healthcare. This framework provides trustless environment decentralized tamper-resistant efficient management data. We first introduce an optimization problem aimed at identifying optimal solution maximum efficiency. Next, classify health based on specific features, sensitivity, requirements. classified then stored three different blockchains (Ethereum, Hyperledger Sawtooth, MultiChain) according their attributes. utilize fog nodes providing computational services resource-constrained Internet Things (IoT) nodes, enabling us perform preprocessing eliminate redundant information from collected Moreover, use differential privacy layer ensure sensitive remains protected throughout analysis process. Finally, present comprehensive attack evaluation performance implementing our real-world dataset. The simulation results indicate HierChain outperforms existing algorithms in terms scalability security degrading IoT network.

Blockchain-Based Intelligent, Interactive Healthcare Systems

Advances in medical technologies and clinical practice book series, Journal Year: 2024, Volume and Issue: unknown, P. 92 - 115

Published: March 11, 2024

When it comes to the smart healthcare sector, blockchain technology presents several prospects. Aside from its usage in financial industry, is now also utilised process of establishing trust, protecting privacy, and ensuring security. Within scope this work, we will provide an explanation a new development business that strives enhance effectiveness safety administration data. We employ construct decentralised tamper-proof network facilitates safe data exchange among stakeholders such as patients, providers, insurers. This technique known Blockchain-based Intelligent Interactive Healthcare Systems (Blockchain-based IHS). The purpose chapter present overview BIIHS, including advantages, disadvantages, potential future paths. BIIHS has patient outcomes by facilitating personalised treatment plans, lowering number medical mistakes, offering real-time access vital sensitive health Nevertheless, order fully realise promise necessary solve problems regulation compliance, interoperability, privacy concerns. Artificial intelligence internet things are two examples upcoming technologies might be included into future. would allow for sector further improve capabilities.
