A Secure Authentication and Key Agreement Protocol for Telecare Medicine Information System
Xuanang Li, Zhiming Zheng, Xiao Li Zhang
Telecare Medicine Information System enables patients to get healthcare services at home expediently and efficiently. Authentication and key agreement protocol suited for TMIS protect patient's privacy via the unsecure network. Recently, numerous protocols have been proposed intend to safeguard the communication between patients and server. However, most of them have high computation overhead and security problems. In this paper, we aim to propose a secure and effective authentication and key agreement protocol using smartcard and password for TMIS. The protocol is based on elliptic curve cryptography. Through security analysis we illustrate that our protocol is secure to resist some known attacks and provide user anonymity. Furthermore, by comparing with other related protocols we show our protocol is superior in security and performance aspects.
