Title (EN) SYSTEM AND METHOD FOR AUTHENTICATING RFID TAGS
(FR) SYSTÈME ET PROCÉDÉ D'AUTHENTIFICATION D'ÉTIQUETTES RFID
Abstract:
(EN) A system and method of providing authenticity to a radio frequency identification (RFID) tag are provided. The method comprises generating a plurality of digital signatures, wherein each digital signature is generated using an index value unique to that digital signature and using information associated with the RFID tag; and storing the plurality of digital signatures on the RFID tag in association with respective index values to enable a desired digital signature to be selected according to a provided index value. Also provided are a system and method of enabling an RFID reader to authenticate an RFID tag, which utilize a challenge comprising an index value to request one of the stored signature and authenticating same. Also provided is an RFID tag that is configured to participate in the challenge-response protocol.
(FR) L'invention concerne un système et un procédé pour assurer l'authenticité d'une étiquette d'identification par radiofréquence (RFID). Le procédé consiste à générer une pluralité de signatures numériques, chaque signature numérique étant générée à l'aide d'une valeur indice unique pour ladite signature numérique et à l'aide d'informations associées à l'étiquette RFID; et à stocker la pluralité de signatures numériques sur l'étiquette RFID en association avec des valeurs indices respectives pour permettre de sélectionner une signature numérique souhaitée en fonction d'une valeur indice fournie. L'invention concerne également un système et un procédé pour permettre à un lecteur RFID d'authentifier une étiquette RFID, lesquels utilisent une interrogation comprenant une valeur indice pour interroger une des signatures stockées et l'authentifier. L'invention concerne en outre une étiquette RFID qui est conçue pour participer au protocole interrogation-réponse.
