On the security of Xu et al.'s authentication and key agreement scheme for telecare medicine information systems

SK Hafizul Islam

Abstract

In 2014, Xu et al. proposed a two-factor mutual authentication and key agreement scheme for telecare medicine information system (TIMS) based on elliptic curve cryptography (ECC). However, it has been shown that Xu et al.'s scheme is not suitable for practical use as it is many problems. As a remedy, an improved scheme is proposed with better security and functionality attributes.
