ESMA-IOMT: Efficient and Secure Mutual Authentication in IoMT With RLWE-Based Encryption and Boneh-Boyen Signatures

The Internet of Medical Things (IoMT) is a promising new frontier in healthcare, enabling remote patient monitoring and telemedicine services. However, it also raises significant security and privacy concerns. To address these challenges, we propose a mutual authentication schema for IoMT using the Ring Learning with Errors (RLWE) and Boneh-Boyen signatures. Our scheme utilizes RLWE-based encryption and Boneh-Boyen signatures to ensure the confidentiality and integrity of data. We validate the authentication of the proposed scheme using Scyther verification and demonstrate its efficiency by performance evaluation. The results of performance evaluation demonstrate that our proposed scheme takes less computation and communication costs compared with other existing solutions. Therefore, it is a fairly attractive solution for efficient and secure mutual authentication in IoMT.
