An Improved Authentication Protocol for Telecare Medical Information System
摘要
In the telecare medicine information system, the importance of patient information system security and mutual authentication is self-evident. In 2017, Aslam et al. considered Kumari et al.'s protocol to be the better of the two-factor authentication protocols they analyzed. We analyze the agreements of Kumari et al. and find some shortcomings. Based on the Computational Diffie-Hellman problem and the timestamp mechanism, we improve the protocol to improve security and use elliptic curves to speed up the calculation. In the comparative analysis of performance and efficiency, we can see that our improved protocol has a smaller calculation amount and higher security.
