Abstract
With the evolution of communication technology and the exponential increase of mobile devices, the ubiquitous networking allows people to use our data and computing resources anytime and everywhere. However, numerous security concerns and complicated requirements arise as these ubiquitous networks are deployed throughout people’s lives. To meet the challenge, the user authentication schemes in ubiquitous networks should ensure the essential security properties for the preservation of the privacy with low computational cost. In 2017, Chaudhry et al. proposed a password-based authentication scheme for the roaming in ubiquitous networks to enhance the security. Unfortunately, we found that their scheme remains insecure in its protection of the user privacy. In this paper, we prove that Chaudhry et al.’s scheme is vulnerable to the stolen-mobile device and user impersonation attacks, and its drawbacks comprise the absence of the incorrect login-input detection, the incorrectness of the password change phase, and the absence of the revocation provision. Moreover, we suggest a possible way to fix the security flaw in Chaudhry et al’s scheme by using the biometric-based authentication for which the bio-hash is applied in the implementation of a three-factor authentication. We prove the security of the proposed scheme with the random oracle model and formally verify its security properties using a tool named ProVerif, and analyze it in terms of the computational and communication cost. The analysis result shows that the proposed scheme is suitable for resource-constrained ubiquitous environments.

Chaudhry et al [32] proposed a privacy-preserving password-based authentication scheme for roaming in ubiquitous networks to solve the security issues of Farash et al.’s scheme [29]. They claimed that their scheme is secure against the various known attacks and is lightweight compared with the earlier scheme of Farash et al [29]
We found that Chaudhry et al.’s scheme [32] is still vulnerable to several attacks; in this paper, we provide the proof that Chaudhry et al.’s scheme [32] is vulnerable to stolen-mobile devices and user impersonation attacks, and has drawbacks to the absence of the incorrect login-input detection, incorrect password change phase, and the absence of the revocation-process provision

They claimed that their scheme is secure against the various known attacks and is lightweight compared with the earlier scheme of Farash et al [29]. Based on recent research efforts [6, 39,40,41], a biometrics-based authentication scheme for roaming in ubiquitous networks should meet the following security requirements against the adversarial model and the functional requirements to provide user-friendliness: 1.

User anonymity: The scheme must ensure the user anonymity to preserve the privacy of MN, i.e., A should not be able to discover the real identity of MN
