Dynamic and Anonymous Authentication Protocol with Evaluation Mechanism for Telecare Medicine

Abstract

Telecare medicine is becoming a trend, due to the combination of traditional medicine and information technology. However, the online communication method leaves patient information at risk of being compromised. Therefore, a dynamic and anonymous authentication protocol for telecare medicine with evaluation mechanism is proposed in our paper. Dynamic and anonymity guarantees patient privacy and security. The differentiated evaluation mechanism not only improves the user’s enjoyment of the experience but also reduces the pressure on the data of trusted authority (TA). Security analysis proves that attacks cannot break our protocol. Finally, our protocol is used to compare with other protocols. It is shown experimentally that our protocol has an advantage over other protocols in terms of computation cost.
