Data protection in public cloud remains a challenging problem. Outsourced data processing on vulnerable cloud platforms may suffer from cross-VM attacks, e.g. side-channel attacks that leak secrecy keys. The authors design and develop CloudSafe, a general and practical data-protection solution by integrating cryptographic techniques and systematic mechanisms seamlessly to address this issue. CloudSafe first allows a data owner to outsource encrypted data in the cloud. It then employs a cloud-based proxy to re-encrypt stored encrypted data and delivers it to authorized cloud applications upon access requests.
