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.
