Title (EN) METHOD FOR ENCODING LONG MESSAGES FOR RSA ELECTRONIC SIGNATURE SCHEMES
(FR) PROCEDE D'ENCODAGE DE MESSAGES LONGS POUR SCHEMAS DE SIGNATURE ELECTRONIQUE A BASE DE RSA
Abstract: front page image
(EN)The RSA encryption algorithm is the most used public key encryption algorithm. The invention concerns a novel message encoding method for signing arbitrarily long messages, without using the hash function. The invention is easily applicable in an electronic component such as a smart card.
(FR)L'algorithme de chiffrement RSA est l'algorithme de chiffrement à clef publique le plus utilisé. L'invention consiste à définir un nouveau procédé d'encodage de message permettant la signature de message arbitrairement longs, sans utiliser de fonction de hachage. L'invention estfacilement utilisable dans un composant électronique de type carte à puce.
