An authentication protocol for telecare medicine information system. (Chinese. English summary) Zbl 1463.68142

Summary: Mutual authentication is one of the most efficient mechanisms to guarantee secure communication between the patient and the medical server in telecare medicine information system (TMIS). We remark that the existing scheme proposed by previous researchers cannot resist offline password guessing attacks and man-in-the-middle attack and preserve forward secrecy. To overcome these limitations, we present a three factor user authentication protocol using extended chaotic maps for TMIS. Further, the proposed protocol is validated using BAN (Burrows-Abadi-Needham) logic. In addition, security analysis of the proposed protocol is to demonstrate its resilience against the well-known malicious attacks. Thus, it is more applicable to telecare medicine environments.
