Abstract

La présente invention concerne un dispositif physique destiné à stocker des clés numériques pour effectuer des transactions sur une chaine de blocs. Le dispositif physique (200) comprend un microphone (213), un haut-parleur (215), un processeur DSP (219) possédant un élément sécurisé dans lequel sont stockés les couples de clés secrètes et de clés publiques, le DSP comprenant en outre un codec acoustique utilisant un dictionnaire, S, dont les mots représentent des signaux ultrasonores aléatoires ou pseudo-aléatoires stockés dans la mémoire du DSP. Le DSP (219) est adapté à décoder un message constitué de mots de S, reçus d'un canal acoustique via le microphone (213), à signer le message ainsi décodé au moyen d'une clé privée et à transmettre la signature ainsi obtenue sous forme d'une réponse constituée de mots successifs de S, sur ledit canal acoustique (250), via le haut-parleur (217).
