Cloud Security Infrastructure (CSI) is a joint research project between Invenia AS and Encap AS of Norway, and Sirrix AG of Germany, where the goal is to come up with a scalable architecture that addresses the security and privacy concerns of cloud storage. In CSI we promote client side end-to-end encryption of all user data. No user data exists unprotected outside the client devices, and the encryption keys are not stored within the storage cloud. Hence there is no means for a cloud provider to access user data. In CSI we apply public key encryption and two-factor authentication to existing cloud storage solutions, providing a highly scalable and secure collaboration environment allowing secure sharing of data. This is integrated with enterprise wide directory services to provide key management within enterprises.
