Secure ECC-Based Three-Factor Mutual Authentication Protocol for Telecare Medical Information System

In the recent COVID-19 situation, Telecare Medical Information System (TMIS) is attracting attention. TMIS one of technologies used in Wireless Body Area Network (WBAN) and can provide patients with a variety remote healthcare services. environments, sensitive data are communicated via an open channel. An adversary may attempt various security attacks including impersonation, replay, forgery attacks. Therefore, numberous authentication schemes have been suggested to secure communication for TMIS. Sahoo et al. proposed mutual scheme based on biometrics Elliptic Curve Cryptography (ECC) 2020. However, we find out that ’s cannot resist insider privileged guarantee patient anonymity. this paper, propose ECC-based three-factor protocol guarantees privacy We conduct informal analysis prove our from addition, perform formal analyses using Automated Validation Internet Security Protocols Applications (AVISPA), Burrows-Abadi-Needham (BAN) logic, Real-Or-Random (ROR) model. Furthermore, assess protocol’s performance compare it other protocols. As result, has lower costs, better features compared related existing more appropriate environments than
