Chip-Secured XML Access (C-SXA) is an XML-based access rights controller embedded in a smart card. C-SXA evaluates user’s privileges on a queried or streaming XML encrypted document and delivers the authorized subset of this document. Compared to existing methods, C-SXA supports fine grain and dynamic access control policies by separating access control issues from encryption. …
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) …
