Special Issue Information

Dear Colleagues, 

Blockchain is a decentralized, distributed ledger technology that ensures data security, transparency, and immutability through a network of nodes that validate and record transactions in linked blocks. It eliminates intermediaries, reduces data tampering, and enhances trust. The IoT is a network of interconnected devices communicating and exchanging data over the internet, enabling real-time monitoring, data collection, and automation across various sectors. The convergence of blockchain and IoT addresses IoT's challenges, such as security, privacy, and interoperability, through secure data exchange, automated processes via smart contracts, and decentralized peer-to-peer communication. This Special Issue aims to explore blockchain's application in enhancing IoT across multiple domains. Specifically, this Special Issue aims to focus on the following:

  • Applying blockchain in healthcare to secure patient data and ensure tamper-proof medical records.
  • Utilizing blockchain for smart cities ensures secure transactions, improving efficiency and trust in city initiatives.
  • Leveraging blockchain in smart navigation secures vehicle-to-vehicle communication, ensuring reliable navigation information.
  • Implementing blockchain for mission-critical IoT systems enhances security and resilience in critical infrastructure and industrial IoT.
  • Employing blockchain in big data ensures decentralized, secure processing, and sharing of IoT-generated data.
  • Using blockchain for supply chain management ensures transparency and traceability, reducing fraud and improving efficiency.
  • Integrating blockchain in agriculture secures IoT sensor data, aiding informed decisions and traceability of agricultural products.
  • Adopting blockchain for energy management secures transactions in smart grids, enhancing energy management efficiency.

The rise of Internet hospitals has significant issues associated with data security and governance in managing sensitive patient data. This paper discusses an alliance blockchain (i.e., a private blockchain) model for governance innovation in internet hospitals with an improved encryption methodology. We compare our proposed model, improved Rivest–Shamir–Adleman (RSA) encryption, integrated into the blockchain framework. Improved RSA achieves impressive improvements in all key metrics by increasing the throughput by 24.7% and lowering the latency by 19.8% compared to the base model. Thus, the improved model is more optimized for processing transactions related to healthcare data. Memory usage was also reduced by 14.3%. While encryption time remained pretty close, the decryption time remarkably improved by 97.5%. IoT sensors are one of the foundations for Internet hospitals that produce consistent patient data streams, such as physiological and environmental metrics. The proposed alliance blockchain model enables the secure and efficient real-time management of this sensor data. These results demonstrate the capability of alliance blockchain and cryptographic upgrades in creating safe and efficient governance frameworks for Internet hospitals. Full article
