Abstract The present invention relates to a method for encrypting digital information using communication devices, which have an interface for a replaceable or writable storage medium, whose content may be read out and duplicated, having a storage medium which is connected to the interface, a supply of symbols for encryption being stored on the digital storage medium, which may be read out on the basis of an address, having an encryption unit which employs the supply of symbols for encrypting and/or decrypting the digital data stream of the communication device on the basis of at least one address. L'invention concerne un procédé pour crypter des informations numériques au moyen de dispositifs de communication, qui présentent une interface pour un support de stockage remplaçable ou réinscriptible, dont le contenu peut être lu ou dupliqué. Ledit support comprend un support de stockage connecté à une interface, une alimentation de symboles destinés au cryptage stockés sur le support de stockage numérique, qui peut être lu sur la base d'une adresse, présentant une unité de cryptage utilisant l'alimentation en symboles pour crypter et/ou décrypter le flux de données numériques du dispositif de communication sur la base d'au moins une adresse.
