Title
(DE) TECHNIK ZUR ERZEUGUNG SYMMETRISCHER VERSCHLÜSSELUNGSALGORITHMEN
(EN) TECHNIQUE TO GENERATE SYMMETRIC ENCRYPTION ALGORITHMS
(FR) TECHNIQUE POUR LA GÉNÉRATION D'ALGORITHMES DE CHIFFREMENT SYMÉTRIQUES
Abstract
(EN) An invention aimed at keeping in a secret and indecipherable form any type of information or data that can be stored, transmitted, displayed or expressed by any means or format, regardless of what its content or purpose may be and to keep the original information inaccessible to unauthorized persons, by means of a cryptographic technique, procedure or process of encryption widely applicable, either physically (hardware), logically (software) or mixed (Firmware) and other forms that may be created in the future. This protected Invention defines a technique, process or procedure for generating multiple encryption or ciphering algorithms with industrial application in both private and public sectors in the areas of national defense, telecommunications, computer science, computer programs, banking and electronic payment transactions, encryption or ciphering of still images, moving images and sounds, in their storage or transmission Including but not limited to the detailed areas, being this list illustrative and not limitative
(FR) L'invention a pour but de garder sous forme secrète et indéchiffrable n'importe quel type de données ou d'information qui peut être stockée, transmise, déployée ou exprimée par l'intermédiaire de n'importe quel média ou format, indépendamment de son contenu ou de l'objet et de garder l'information originale inaccessible à des personnes non autorisées, par le biais d'un processus, d'un procédé ou d'une technique de cryptographie pour un chiffrement de vaste application physique (matériel), logique (logiciel), mixte (micrologiciel) et d'autres formes qui peuvent se créer dans le futur. Cette invention concerne une technique ou un procédé de génération d'algorithmes multiples de chiffrement de large application industrielle tant dans les secteurs privés que publics dans les domaines de la défense nationale, des télécommunications, de l'informatique, des programmes d'ordinateur, des transactions bancaires et des paiements électroniques, de le cryptographie d'images fixes, en mouvement et de sons, dans leur stockage ou leur transmission, incluant les domaines énumérés mais ne s'y limitant pas, cette liste étant illustrative et non limitative.
