A secure blockchain-assisted authentication framework for electronic health records

The evolution of internet technology has significantly broadened the accessibility of E-healthcare services, with Electronic Healthcare Records (EHR) holding a pivotal role in this transformation. EHR facilitates the transition from traditional, centralized paper-based healthcare records to a more efficient electronic system, ensuring proper regulation. With increasing data exchange over the internet, data security is paramount. This research presents a secure authentication framework for EHR, leveraging blockchain technology to ensure data security in an era of heightened data exchange over the Internet. The framework’s robustness is validated using the formal and informal security analysis, along with simulations through the Scyther tool. A performance comparison demonstrates its superiority in terms of communication overhead, computation cost, and processing time, making it a promising solution for secure authentication in E-healthcare systems.
