PROCÉDÉ PERMETTANT DE GÉNÉRER DES CODES D'OUVERTURE D'UN RÉSERVOIR ET PROCÉDÉ D'OUVERTURE D'UN RÉSERVOIR

摘要

A generation process (110, 120) of codes for opening a tank (2) is provided, comprising a cap (3) closing the tank (2) and comprising an identifier, a first clock (35), a first token generation unit (36), a control device (4) suitable to perform an exchange between the cap (3) and control device (4) and comprising a second clock (41), a cap database associating the cap (3) to the identifier and a second token generation unit (42); a first computation step (111, 121 ) wherein a unit (36, 42) determines a code base according to the code base and a time stamp of a clock (35, 41); an encryption step (112, 122) wherein a unit (36, 42) calculates an encrypted code by encrypting the identifier; a second computation step (113, 123) wherein the unit (36, 42) determines the intermediate code as a function of the encrypted code; an extraction step (114, 124) wherein a unit (36, 42) defines a token as a portion of the intermediate code.
