A Cloud-Based Model to Facilitate Mobility of Privacy-Preserving Attribute-Based Credential Users

Deploying the full ecosystem of Privacy-preserving Attribute-based Credentials requires the involved entities to employ and operate some software/hardware packages on their domains. This also holds for the Privacy-ABC users, as they need to run a User Agent, which acts on their behalf and performs some computations locally when authenticating towards Service Providers. If the user wishes to use multiple workstations, currently there is no solution other than installing the User Agent on every device. This introduces barriers to their mobility and causes inconvenience, which can negatively influence adoption of such technologies. In this paper, we aim at a Software-as-a-Service approach and suggest an install-free architecture that lifts the aforementioned barriers.
