Since it is practically impossible to model, copy, or control the IC manufacturing process variations, PUFs not only make these chips unique, but also effectively unclonable. Exploiting the inherent variations in the IC manufacturing process, PUFs provide a secure, robust, low cost mechanism to authenticate silicon chips. This makes PUFs attractive for RFID ICs where cost and security are the key requirements. In this paper we present the design and implementation of PUF enabled “unclonable” RFIDs. The PUF-enabled RFID has been fabricated in 0.18 � technology, and extensive testing results demonstrate that PUFs can securely authenticate an RFID with minimal overheads. We also highlight the advantages of PUF based RFIDs in anti-counterfeiting and security applications. I.

D'une maniere generale, ce dispositif comprend un serveur central qui possede une liste d'algorithmes se rapportant a des numeros de telephone d'acces, ces numeros appartenant a des fournisseurs d'acces a Internet parmi lesquels il est possible de choisir. Ce dispositif de routage central comprend egalement une unite d'identification automatique de numeros de telephone, laquelle va identifier les appels entrants afin de pouvoir identifier un utilisateur comme un client. Un generateur d'algorithmes va decharger des algorithmes se rapportant a des numeros de telephone particuliers, ceci de maniere a ce que l'utilisateur puisse acceder a divers fournisseurs d'acces a Internet. Ce dispositif de routage central permet a un utilisateur de choisir parmi un certa...
