Blockchain‐Enabled Edge‐ <scp>IoT</scp> Framework for Securing Smart Healthcare Management System

ABSTRACT The enormous potential for healthcare data management to deliver efficient and economical patient care has gained increasing attention in recent years. The Internet of Things (IoT), now reaching full maturity due to the rapid advancement of communication technologies, is expanding rapidly as large volumes of data are generated and transmitted. This growth introduces complex performance demands for controlling devices deployed globally. Most existing IoT healthcare infrastructures are highly centralized, leading to issues such as single points of failure and increased susceptibility to cyberattacks. To ensure secure and verified data interoperability, the blockchain paradigm introduces promising mechanisms for enhancing privacy, security, and decentralization. In this work, a blockchain‐enabled edge‐IoT framework is presented for securing smart healthcare management by minimizing network latency and computational complexity. The framework ensures data integrity and enables secure, immutable logging of patient information across distributed devices. It also supports real‐time monitoring and control through IoT smart devices, reducing risks in critical healthcare scenarios. Formal security validation was conducted using the AVISPA tool to assess the authentication protocol. Simulation and performance analysis using iFogSim and IoTSim‐Edge demonstrated a 94.6% reduction in execution time and up to 15% energy savings, validating the framework's scalability and effectiveness compared to conventional cloud‐based models.
