Recent research studies have demonstrated that secured medical data sharing greatly enhances people's quality of life through improving medical treatment and care. The challenges associated with the safety of medical data make it even more difficult for the whole healthcare system to be interoperable. When it comes to striking a balance within the field of healthcare, blockchain technology has begun to emerge as a significant option. It is hard to find well-established solutions, nonetheless, due to the ongoing development of innovative Blockchain technology and the transformation of healthcare facilities. The main purpose of this paper is to develop the most straightforward and efficient security paradigm known as, Healthcare - Blockchain paired with homomorphic encryption (H-BlockEnc) framework for IoT-healthcare systems. Here, cutting-edge blockchain technology has been used to quickly and cheaply secure the safety and confidentiality of medical data. In addition, for increased security and data privacy, the homomorphic encryption standard is also utilized for cryptographic activities. The Beetle Swarm Optimization (BSO) technique is used throughout this process to generate keys as efficiently as possible. Based on processing time, energy consumption, block count, and loss rate, the performance and security level of the suggested H-BlockEnc model are verified and contrasted.
