| Abstract: |
| This study proposes a cloud-assisted, user-centric, and secure data circulation scheme, referred to as CADC (user-centric secure cloud-assisted cross-application data circulation scheme). It enables convenient authentication and on-demand trusted data circulation for mobile users in a multi-App environment, allowing the unlocking of data value in mobile networks. Formal security analysis demonstrates that CADC can resist semi-honest cloud service providers and App service providers. Performance evaluation results indicate that CADC is highly efficient for both users and Apps. |
