Title (EN) METHOD FOR SECURED OFFLINE TRANSFER OF DOCUMENTS VIA DYNAMIC TWO-DIMENSIONAL BARCODE
(FR) PROCÉDÉ DE TRANSFERT HORS LIGNE SÉCURISÉ DE DOCUMENTS PAR L'INTERMÉDIAIRE D'UN CODE À BARRES BIDIMENSIONNEL DYNAMIQUE
Abstract:
(EN) Method for secure transmission of data (200) between two mobile devices via at least one 2D barcode comprising: a first mobile device generating (201) a signed timestamp using a sender private key; converting (202) a signed data block and the signed timestamp into at least one 2D barcode; the signed data block includes a data and a sender public key pre-signed by a first private key; displaying (203) the 2D barcode on a display unit for a second mobile device to scan and retrieve the 2D barcode; retrieving (204), by the second mobile device, the signed data block and the signed timestamp by decoding the 2D barcode; decoding (205,206) the signed data block using a first public key to retrieve and verify the data and the sender public key; decoding (207) the signed timestamp using the verified sender public key to retrieve and verify the timestamp.
(FR) La présente invention concerne un procédé de transmission sécurisée de données (200) entre deux dispositifs mobiles par l'intermédiaire d'au moins un code à barres 2D qui comprend : un premier dispositif mobile générant (201) un indicateur temporel signé à l'aide d'une clé privée d'expéditeur ; la conversion (202) d'un bloc de données signé et de l'indicateur temporel signé en au moins un code à barres 2D ; le bloc de données signé comprend des données et une clé publique d'expéditeur pré-signée par une première clé privée ; l'affichage (203) du code à barres 2D sur une unité d'affichage pour un second dispositif mobile afin de balayer et de récupérer le code à barres 2D ; la récupération (204), par le second dispositif mobile, du bloc de données signé et l'indicateur temporel signé par décodage du code à barres 2D ; le décodage (205, 206) du bloc de données signé utilisant une première clé publique afin de récupérer et vérifier les données et la clé publique d'expéditeur ; le décodage (207) de l'indicateur temporel signé à l'aide de la clé publique d'expéditeur vérifiée afin de récupérer et vérifier l'indicateur temporel.
