Abstract
With the recent tremendous growth in technology, the Internet of Things (IoT) Telecare Medicine Information System (TMIS) is the most widely used medical information system with prominent achievements. Authentication schemes, which use Smart cards, offer the best solution for TMIS applications that in turn provide efficiency and security. Furthermore, authentication schemes that combine passwords and smart cards are considered to be an effective solution for the two-factor authentication scheme. Such schemes contribute to high security along with the public-key cryptosystem. In this research work, a two-factor authentication technique that is both efficient and secure, which makes use of Elliptic Curve Cryptography (ECC) with smart cards, has been proposed. Here, we have used the fundamental assumptions of strong and collision free cryptographic Hash function and Elliptic Curve arithmetic. The proposed authentication technique protects user privacy by allowing registered users to change their passwords without revealing their identity to the server. The proposed authentication scheme has been subjected to formal and informal security investigations. In terms of efficiency and performance, the proposed two-factor authentication technique was compared with the existing relevant two-factor authentication schemes based on ECC. This scheme satisfies the two-factor authentication scheme's basic security standards.

Summary
It is related to the need for information and communication technology in hospitals and medical institutions for telecare medical information systems that permits medical personnel and patients to perform remote medical care services via the Internet, lowering medical costs and reducing time-consuming hospital visits. e digital revolution has ushered in a slew of new opportunities across the board, and it has boosted the use of information technology. Almost every remote user authentication solution is based on the use of smart cards. Most of the researchers are focusing on developing more secure and highly efficient remote authentication schemes using two factors. Using Elliptic Curve Cryptography (ECC), we have suggested an efficient and secure two-factor authentication approach for the Telecare Medical Information System (TMIS). (1) is particular work proposes an efficient and provably secure two-factor user authentication scheme based on Elliptic Curve Cryptography (ECC) using smart cards. E following sections are structured throughout this study effort; Section 2 contributes a quick review of the two-factor authentication protocol for Telecare Medical Information System (TMIS). E comprehensive performance study, which covers both computational and communication expenses, is explained in Section 7. e findings in 8 brought our scheme to a conclusion
