CREDENTIAL: A Framework for Privacy-Preserving Cloud-Based Data Sharing

Kurzfassung (in Englisch):

Data sharing -- and in particular sharing of identity information -- plays a vital role in many online systems. While in closed and trusted systems security and privacy can be managed more easily, secure and privacy-preserving data sharing as well as identity management becomes difficult when the data are moved to publicly available and semi-trusted systems such as public clouds. CREDENTIAL is therefore aiming on the development of a secure and privacy-preserving data sharing and identity management platform which gives stronger security guarantees than existing solutions on the market. The results will be showcased close to market-readiness through pilots from the domains of eHealth, eBusiness, and eGovernment, where security and privacy are crucial. From a technical perspective, the privacy and authenticity guarantees are obtained from sophisticated cryptographic primitives such as proxy re-encryption and redactable signatures.
