Due to real-time data sharing in the Internet of Medical Things (IoMT), the healthcare sector has evolved significantly in recent years. However, security breaches reveal incorrect authenti- cation and susceptible access during EHR distribution of EHRs among various stakeholders. Thus, a primary objective of the National Digital Health Mission (NDHM) is to employ cutting-edge technology to strengthen the security of electronic health records (EHRs) while safeguarding patient privacy. This paper proposes a signcryption with an identity-based authentication protocol based on Elliptic curve cryptography securing the transmission of medical records. The proposed protocol is designed based on bilinear pairing, and it supports several security features, including data confidentiality and au- thentication with effective key management. The proposed protocol is shown formally complete using BAN logic. Besides, our protocol is shown secure against potential attackers using the AVISPA under the OFMC and Cl-AtSe models. Nonetheless, the empirical analysis demonstrates that the proposed protocol outperforms the existing related schemes. Therefore, our proposed protocol is more suitable to be applied in the Internet of Medical Things (IoMT) environment.
