Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif d'authentification pour un équipement à communication en champ proche (NFC), comprenant les étapes suivantes : lors de la détection des opérations d'approche d'équipement NFC à vérifier, obtenir la fréquence d'approche de l'équipement NFC à vérifier en moins d'une durée prédéfinie et dans un intervalle de temps entre les opérations d'approche adjacentes, et détecter si un résultat de vérification de chaque opération d'approche respecte les exigences ou non ; et si les conditions sont respectées, effectuer des opérations de service suivantes après la réussite de l'authentification de l'équipement NFC à vérifier. Par conséquent, même si des informations sécurisées dans l'équipement NFC à vérifier sont clonées, un intrus ne pourrait pas apprendre la règle pour les opérations d'approche, et ainsi l'autorisation d'accès ne pourrait pas être obtenue, ce qui améliore la sécurité pour l'authentification de l'équipement NFC.
