Abstract

La présente invention concerne un procédé de messagerie sécurisée, comportant une étape d'exploitation avec une opération d'authentification de l'utilisateur et de validation de l'authenticité de l'utilisateur par comparaison entre la valeur dérivée d'un chaîne de caractère secrète transmise par l'utilisateur, et d'une valeur dérivée stockée dans une base de données, en relation avec l'dientifiant de l'utilisateur considéré, et une opération de transmission par le serveur vers le poste utilisateur de ladite bi-clé, puis consistant à chiffrer et/ou signer le message préparé sur le poste client avec respectivement les clés privées des destinataires du message, et/ou la clé privée dudit utilisateur, l'opération de transmission du message étant réalisée par l'établissement de canaux virtuels [VPN] pour le chiffrement et/ou la signature, la compression et la transmission du message étant réalisées 'en flux continu' [streaming] sans stockage temporaire en mémoire sur le poste client, ni sur le serveur, ni sur un poste périphérique.
