Résumé
The Digital Rights Management (DRM) principle is generally well known for the exchange of files (music, video), or software management. Specialized solutions concerning vprofessional software are behind a business called "Software License Managemen". The concept of DRM can be transposed to other areas, in particular to the design of hardware devices. Although the concept of DRM is allowed and widely used in the field of software, this is not the case for Integrated Circuit design (no industrial solutions to date are actually proposed). We propose into this paper a new approach based on a original way to extract Physically Unclonable Function which is at the heart of the DRM proposal.
