Design of Robust Blockchain-Envisioned Authenticated Key Management Mechanism for Smart Healthcare Applications

The healthcare sector is a very crucial and important sector of any society, and with the evolution of the various deployed technologies, like the Internet of Things (IoT), machine learning and blockchain it has numerous advantages. However, in this section, the data is much more vulnerable than others, because the data is strictly private and confidential, and it requires a highly secured framework for the transmission of data between entities. In this article, we aim to design a blockchain-envisioned authentication and key management mechanism for the IoMT-based smart healthcare applications (in short, we call it SBAKM-HS). We compare the various attributes of the proposed SBAKM-HS and other existing schemes to demonstrate that SBAKM-HS outperforms other existing schemes. The conducted security analysis and formal security verification via Scyther automated validation tool prove the security of the proposed SBAKM-HS against various possible potential attacks. Next, a real-tested implementation of SBAKM-HS is provided to observe its impact on the performance of the system.
