    Abstract: Nowadays users can access various online services and
    resources from distributed information systems remotely via Internet or
    other public networks. However, remote online systems are vulnerable to
    many security attacks due to they are built on public networks. Therefore
    it is necessary to design an authentication scheme for securing network
    communications between a login user and a remote server. In 2016, Han
    et al. proposed a secure three-factor authentication scheme based on
    elliptic curve cryptography (ECC) to achieve this goal. Unfortunately,
    we analyzed Han et al.’s scheme and demonstrated that their authentication
    scheme cannot satisfactory to be implemented in practice because
    it fails to ensure the property of unlinkability between the login user and
    the remote server and is unable to withstand account duplication attack.
    In this paper, we suggest an enhanced anonymous authentication scheme
    to repair the security flaws in Han et al.’s scheme. We give the security
    analysis and performance evaluation to demonstrate that the proposed
    scheme not only resists the aforementioned security weaknesses on Han
    et al.’s scheme but also inherits the functionality merits and performance
    efficiencies of their authentication scheme.
