Abstract: As internet of medical things (IoMT) devices proliferate, the need for robust security measures becomes paramount to protect sensitive health information from cyber threats and unauthorized access. Therefore, this paper proposes a blockchain-enabled with elliptic curve cryptography (ECC) to bolster security and privacy in medical data transmission. The proposed framework leverages the decentralized nature of blockchain, ensuring data integrity and transparency while utilizing ECC for efficient encryption and decryption processes. This combination not only addresses the scalability and performance issues associated with traditional cryptographic methods but also facilitates secure data sharing among healthcare stakeholders. Through a series of experiments and comparative analyses, the effectiveness of the proposed system is evaluated, demonstrating significant improvements in security resilience and operational efficiency. The findings highlight the potential of blockchain-enabled ECC as a transformative solution for securing IoMT ecosystems, ultimately contributing to safer and more reliable healthcare services.
