Title (EN) QUANTUM TOKENS
(FR) JETONS QUANTIQUES
Abstract:
(EN) Secure, semi-classical authentication schemes are presented. An authentication token is generated by applying a pre-determined measurement to a plurality of random quantum states to obtain a sequence of classical measurement outcomes. The token is validated by receiving the classical measurement outcomes and verifying whether the sequence corresponds to a statistically plausible result for the pre-determined measurement of the plurality of quantum states.
(FR) L'invention concerne des schémas d'authentification semi-classiques sécurisés. Un jeton d'authentification est généré en appliquant un mesurage prédéterminé à une pluralité d'états quantiques aléatoires pour obtenir une séquence de résultats de mesurage classique. Le jeton est validé par la réception des résultats de mesurage classique et la vérification du fait que la séquence correspond à un résultat statistiquement plausible du mesurage prédéterminé de la pluralité d'états quantiques.
