Secure Identity-Based Authentication Scheme Suitable for Limited-Resource Devices

摘要

In the internet banking environment, using credit cards to pay the services is one of the most popular and simplest methods. However, this is dangerous if users information or smart-card is stolen. With a non-stop development of mobile and wearable devices, user authentication scheme which is security and low-resource efficient is a subject of interest. Modern devices help securing login phase by exploit biometrics collecting from them. Recently, Saru Kumari et al. proposed a remote scheme with key agreement to overcome popular kinds of attacks. However, in this paper, we realize their scheme is still vulnerable to two-factor attack and does not achieve user anonymity. In addition to security analysis, we presented an improved scheme to have a better solution with elliptic curve cryptosystem.
