Verifiable and Controllable Data Sharing With Compliance Checking in Cloud Computing
- Published
- Record updated
Summary
The paper introduces Verifiable Data Capsule (VDC), a scheme for controllable data sharing in cloud computing that lets users verify data capsules and state updates. It proposes a Locally Verifiable Chameleon Tag (LVCT) that binds all data capsules to a constant-size tag, a dual-level authentication structure for verifiable updates, and a trust evaluation protocol for judging cloud server credibility. The authors report security analysis and performance evaluation showing practicability.
