【 摘 要 】

Due to the rapid development of physiological monitoring devices, internet of things (IoT) and communication technology, telecare medical information systems (TMIS) are getting more and more important in assisting doctors in completing medical work nowadays. Because of the open nature of wireless networks, a secure TMIS which offers authentication, anonymity and privacy features is required. There are many schemes protecting TMIS that have been proposed recently. Unfortunately, they cannot guarantee both patient’s and doctor’s privacy and security at the same time. This paper proposes a ring signature-based TMIS authentication scheme for a group consultation environment. In our proposed scheme, a patient can inquire about their symptoms without revealing their identity, and a doctor can also keep their own identity confidential when making a diagnosis. In view of the increasing number of serious patient–physician disputes, our proposed scheme can have a practical application. Compared to other related work, our scheme achieves improved security properties and higher efficiency.
