MRDT: An Enhanced Multireceiver Secure Data Transmission Protocol for WBANs

Wireless body area networks (WBANs) have gained significant attention due to their numerous advantages in healthcare monitoring and applications. However, WBANs also face challenges related to data transmission security and privacy protection. Many researchers have proposed solutions to address these issues, but most of them are based on one-to-one communication models, which suffer from security vulnerabilities. Hence, we first review the previous protocol and show potential attack scenarios. Building upon their work, we propose an enhanced certificateless multireceiver secure data transmission protocol for WBANs. Our proposal addresses security concerns and improves the efficiency and practicality of data transmission in WBANs. The security analysis and performance evaluation demonstrate that the proposed protocol achieves higher security levels, increases efficiency, and enhances practicality compared to existing approaches. Furthermore, our protocol provides a reliable framework for secure data transmission in WBANs, ensuring the privacy of users and maintaining the integrity and confidentiality of sensitive medical information.
