Identity-Based Authenticated Encryption in Internet of Medical Things

This paper introduces an authentication protocol that relies on identity-based authentication to safeguard the medical data system in the Internet of Medical Things (IoMT). The protocol uses Public-Key algorithms to control access and generate secure session keys. To ensure the confidentiality and integrity of data, both the Counter CBC-MAC Mode and Galois Counter Mode are utilized to perform authenticated encryption protocols. Our proposed protocols are developed based on user identities associated with their secret keys. In the IoMT, authorized users with valid identities can access encrypted medical records. The results demonstrate that our proposed protocols protect against statistical and differential attacks. The computational cost of the secure protocols is also suitable for medical data management systems, as it requires low resource utilization.
