C-SDA: Chip-Secured Data Access

The Chip-Secured Data Access (C-SDA) architecture allows querying encrypted data while controlling fine grain and dynamic personal privileges. The application domain of C-SDA covers the protection of databases hosted by untrusted Database Service Providers as well as the protection of database servers against external and internal piracy. The CNRS (Centre National de la Recherche Scientifique) took out a patent on C-SDA. A JavaCard prototype has been developed partly with the support of the French ANVAR agency (Agence Nationale pour la Valorisation de la Recherche) and has been demonstrated at the VLDB’03 conference.More info on C-SDA
