Title (EN) METHOD FOR ESTABLISHING A SECURED COMMUNICATION WITHOUT PRELIMINARY INFORMATION SHARE
(FR) PROCÉDÉ D'ÉTABLISSEMENT DE COMMUNICATION SÉCURISÉE SANS PARTAGE D'INFORMATION PRÉALABLE
Abstract:
(EN) The invention relates to a method for generating a session key between two communicating electronic devices not requiring any prerecorded information in one of the two devices and enabling the authentication of one of said devices. The method uses a close collaboration between a symmetrical algorithm and an asymmetrical algorithm.
(FR) Procédé de génération d'une clé de session entre deux dispositifs électroniques communicants ne nécessitant aucune information préenregistrée dans un des deux dispositifs et permettant d'authentifier l'un des dispositifs. Ce procédé utilise une collaboration étroite d'un algorithme symétrique et d'un algorithme asymétrique.
