PRISMACLOUD - PRIvacy and Security MAintaining Services in the CLOUD

PRISMACLOUD is an EU-funded research project developing the next generation of cloud security technologies. The project uses novel cryptographic concepts and methods in practical applications, designed to improve the security and privacy of cloud-based services and make them usable for providers and users. The main idea and goal of PRISMACLOUD is to enable end-to-end security for cloud users, and to provide tools which protect their privacy using the best technical means possible - by cryptography.

With a current volume of over USD 100 billion and annual growth rates of over 10%, the global market for cloud computing can be considered as the major growth area in ICT. However, big companies and public authorities are reluctant to entrust their most sensitive data to external parties for storage and processing. The reason for their hesitation is clear: no satisfactory approaches to adequately protect the data during its lifetime in the cloud currently exist. PRISMACLOUD addresses these challenges and yields a portfolio of novel, security-enabled cloud services, guaranteeing the security required for sensitive data in the cloud.

Techniques for outsourcing computation with verifiable correctness and authenticity preservation allow computations to be securely delegated to cloud providers. A distributed multi-cloud data storage architecture shares data among several cloud providers and improves security and availability. Dynamically updating shares by means of novel techniques avoids vendor lock-in, preserves data authenticity, facilitates long-term privacy and promotes a dynamic cloud provider market. Claims about the secure connection and configuration of the virtualized cloud infrastructures and properties of cloud topologies are verifiable by means of cryptographic techniques. User privacy issues are addressed by data minimization and anonymization technologies via the application of privacy-preserving cryptographic techniques. As proof of feasibility, three use cases from the fields of Smart City, e-Government, and e-Health will be implemented and evaluated by the project participants.

The PRISMACLOUD work programme is complemented with activities addressing secure user interfaces, secure service composition, and secure implementation in software and hardware, security certification, and an impact analysis from an end-user view. In order to converge with the European Cloud Computing Strategy, a strategy for the dissemination of results into standards is being developed.
