Abstract
La présente invention concerne un procédé pour partager des données entre des acteurs (5) d'un réseau, ledit procédé comprenant une étape de cryptographie des données par une méthode cryptographique asymétrique à double clés, chaque acteur (5) possédant au moins une dite double clés. Le procédé comporte une étape d'initialisation (STP1) d'une la chaîne de blocs qui comporte une opération de mémorisation d'au moins un bloc d'initialisation (26) par une autorité prédéterminée à l'aide d'au moins un ordinateur, ledit au moins un bloc d'initialisation (26) comprenant au moins une dite transaction (36) qui inclut un enregistrement d'identité (84) d'un acteur majeur, ladite autorité n'intervenant plus à l'issue de l'étape d'initialisation (STP1) au moins en dehors d'une étape de réinitialisation d'un acteur.The present invention relates to a method for sharing data between actors (5) of a network, said method comprising a step of encrypting the data by an asymmetric cryptographic method with double keys, each actor (5) having at least one said double keys. The method comprises a step of initialization (STP1) of a block chain which comprises an operation of memorizing at least one initialization block (26) by a predetermined authority using at least one computer , said at least one initialization block (26) comprising at least one said transaction (36) which includes an identity record (84) of a major player, said authority no longer intervening at the end of the initialization step (STP1) at least outside of an actor reset step.
