Abstract
(EN) This disclosure relates to a data storage device. A data port transmits data between a host computer system and the data storage device over a data channel. The device repeatedly broadcasts advertising packets over a wireless communication channel different from the data channel. Each advertising packet comprises a random value and a message authentication code calculated based on the random value and an identity key. The identity key is readable by a device to be connected and in proximity of the data storage device out of band of the data channel and the communication channel. The identity key enables the device to be connected to verify the message authentication code based on the random value and the identify key to thereby authenticate the data storage device.
(FR) La présente invention concerne un dispositif de stockage de données. Un port de données transmet des données entre un système informatique hôte et le dispositif de stockage de données sur un canal de données. Le dispositif diffuse de manière répétée des paquets d'annonce sur un canal de communication sans fil différent du canal de données. Chaque paquet d'annonce comprend une valeur aléatoire et un code d'authentification de message calculé en fonction de la valeur aléatoire et d'une clé d'identité. La clé d'identité peut être lue par un dispositif à connecter et à proximité du dispositif de stockage de données hors de la bande du canal de données et du canal de communication. La clé d'identité permet au dispositif d'être connecté pour vérifier le code d'authentification de message en fonction de la valeur aléatoire et de la clé d'identification pour ainsi authentifier le dispositif de stockage de données.
