An improved anonymous authentication scheme for telecare medical information systems.

Telecare medical information system (TMIS) constructs an efficient and convenient connection between patients and the medical server. The patients can enjoy medical services through public networks, and hence the protection of patients' privacy is very significant. Very recently, Wu et al.

A more secure anonymous user authentication scheme for the integrated EPR information system.

Secure and efficient user mutual authentication is an essential task for integrated electronic patient record (EPR) information system. Recently, several authentication schemes have been proposed to meet this requirement. In a recent paper, Lee et al.

A robust uniqueness-and-anonymity-preserving remote user authentication scheme for connected health care.

User authentication plays an important role to protect resources or services from being accessed by unauthorized users. In a recent paper, Das et al. proposed a secure and efficient uniqueness-and-anonymity-preserving remote user authentication scheme for connected health care.
