Title (EN) ASYMMETRIC CRYPTOGRAPHY WITH USER AUTHENTICATION
(FR) CRYPTOGRAPHIE ASYMETRIQUE A AUTHENTIFICATION D'UTILISATEUR
Abstract: front page image
(EN)A device uses a user authentication factor to generate a decryption key for use in asymmetric cryptography. An encryption key is generated from the decryption key using a one-way function.
(FR)Ce dispositif utilise un facteur d'authentification d'utilisateur pour générer une clé de décryptage utilisée dans la cryptographie asymétrique. Cette clé est générée à partir de la clé de décryptage au moyen d'une fonction unidirectionnelle.
