Abstract

La présente invention concerne un procédé pour échanger des données entre des acteurs (5) d'un réseau (10), ledit procédé comprenant une étape de cryptographie des données par une méthode cryptographique asymétrique à double clés, chaque acteur (5) étant associé à une double clés comprenant une clé privée et une clé publique. Une chaîne de blocs (20) étant mise en œuvre, un bloc (25) comprenant une empreinte numérique du bloc qui le précède dans la chaîne de blocs (20) et au moins une transaction (35). Durant une étape de création, au moins un bloc de la chaîne de blocs dit « bloc d'initialisation » est créé, pour chaque acteur au moins un « bloc d'initialisation » comprenant une transaction dite « transaction d'identification (36) », chaque transaction d'identification (36) comprenant des données dites « données d'identification » de cet acteur, lesdites données d'identification incluant la clé publique de la double clés de cet acteur et au moins une information identifiant cet acteur.The present invention relates to a method for exchanging data between actors (5) of a network (10), said method comprising a step of data cryptography by an asymmetric double-key cryptographic method, each actor (5) being associated with a double key comprising a private key and a public key. A blockchain (20) being implemented, a block (25) comprising a digital fingerprint of the block preceding it in the blockchain (20) and at least one transaction (35). During a creation step, at least one block of the chain of blocks called “initialization block” is created, for each actor at least one “initialization block” comprising a transaction called “identification transaction (36)” , each identification transaction (36) comprising data called “identification data” of this actor, said identification data including the public key of the double keys of this actor and at least one piece of information identifying this actor.
