In the forthcoming Smart City scenario, users' mobile applications will be of fundamental role towards supporting the envisioned functionalities and services. Mobile users, provided with a smartphone, will be capable of ubiquitously connecting to service providers through their installed mobile applications. However, this connection must be authenticated, which threatens the citizen privacy rights. Privacy-preserving mechanisms have already been proposed in the past; nevertheless, they are based on RSA groups or groups with bilinear pairings, which are inefficient in mobile devices due to its computational complexity. Thus, in this paper, we integrate a lightweight anonymous credential mechanism, suitable for computationally-limited mobile devices, into the user authentication phase of the OAuth2 protocol, which has become a de facto solution for user authentication in mobile applications. The proposed protocol enables citizen's authentication towards service providers, while preserving their privacy. Additionally, the protocol is compliant with the OAuth2 specification, which enables an easy integration in current mobile application implementations.
