Abstract: Medical field is one of the many important fields that keeps growing day by day. Since health care is essential for every human being, development of medical systems play a vital role in the overall development of society. With the help of the Internet, medical services are provided through TMIS (Telecare Medicine Information System). During the process, information related to patient is transmitted over open channels and ensuring safety to this information is an essential task. For this, a number of remote user authentication schemes have been proposed and evolved over the time. Chen et al. proposed an authentication scheme for TMIS in 2018. Through analysis of their scheme, it has been shown that their scheme cannot withstand user impersonation attack, server masquerading attack, password guessing attack and cannot preserve user anonymity. These weaknesses have been presented in this paper. In addition to this, an improved scheme has been proposed which overcomes the aforementioned security defects. Also, this paper discusses the security analysis of the proposed scheme, which proves that it is more secure and can be practically implemented. � 2018 ACM.
