Abstract
Smart Health Care provides efficient, sustainable, and real-time human services, with its development rooted in the idea of an improved Internet of Things (IoT). However, the integration of these IoT-centric devices with other organizations raises security concerns, as unauthorized users may exploit the available data. Given that alterations in data values from sensors can impact the diagnostic process, potentially leading to severe health issues, ensuring data security and privacy emerges as a paramount concern in the healthcare industry. The Internet of Medical Things (IoMT) signifies a set of healthcare technology that allow care providers, doctors, and medical testing establishments to store and share health data automatically. Despite this, guaranteeing data privacy protection during IoMT transmission is a difficult challenge. To solve these issues, the combination of blockchain (BC) and IoMT provides resilience against multiple attacks while maintaining anonymity. Blockchain successfully enables peer-to-peer data transmission, detecting a large number of potential dangers. The creation of blockchain networking based on the TDES-EKMC addresses the limitations of blockchain networking in the IoMT domain. For user mutual authentication, the proposed framework employs the ECMQV-MAC protocol, the DC-PC for data storage module, and the DM-BGC for key generation. This protocol assures that users have the legal right to use blockchain networking (BCN), while also avoiding superfluous data storage in the blockchain. The key generation process strengthens data privacy defenses against both internal and external attacks. Finally, authorized users can contribute healthcare data to the blockchain, and TDES-EKMC provides secure data transmission in blockchain networking. The suggested framework beats the traditional state-of-the-art technique in terms of throughput, Packet Delivery Ratio (PDR) value, privacy leakage, and the additional time necessary to build new blocks, according to test findings.
