CERIAS Tech Report 2005-11 REMOTE REVOCATION OF SMART CARDS IN A PRIVATE DRM SYSTEM

Remote Revocation of Smart Cards in a Private DRM System

We describe a DRM smartcard-based scheme in which content access requests are not linked to a user’s identity or smartcard, and in which compromised cards can be revoked without the need to communicate with any card (whether revoked or not). The scheme has many other features, such as efficiency and requiring minimal interaction to process an access request (no complex interactive protocols), f...

CERIAS Tech Report 2004-41 PORTABLE AND FLEXIBLE DOCUMENT ACCESS CONTROL MECHANISMS

We present and analyze portable access control mechanisms for large data repositories, in that the customized access policies are stored on a portable device (e.g., a smart card). While there are significant privacy-preservation advantages to the use of smart cards anonymously created and bought in public places (stores, libraries, etc), a major difficulty is that, for huge data repositories an...

Identity Based Drm System with Total Anonymity and Device Flexibility Using Ibes

Most of the Digital Rights Management (DRM) systems fail to cover all requirements like user anonymity, user fairness, security and others. Device based DRM systems, adopted by most providers, lack user fairness and mostly follow proprietary formats. On the contrary, Smart Card DRM systems satisfy user anonymity and fairness, but have certain vulnerabilities, as identified in this paper. We pro...
