Résumé:

Cloud computing can help reduce costs, increase business agility and deploy solutions with a high return on investment for many types of applications, including data warehouses and on-line analytical processing. However, storing and transferring sensitive data into the cloud rais-es legitimate security concerns. In this paper, we propose a new multi-secret sharing approach for deploying a data warehouse in the cloud and allowing on-line analysis processing, while enforcing data privacy, integrity and availability. We first validate the relevance of our ap-proach theoretically, and then experimentally with both a simple random dataset and the Star Schema Benchmark. We also demonstrate its superiority to related, existing methods.
