Title (EN) AN ENCRYPTION METHOD AND SYSTEM FOR MOBILE TELEPHONES
(FR) PROCEDE ET SYSTEME DE CRYPTAGE POUR TELEPHONES MOBILES
Abstract:
(EN) This invention relates to a method and system for transfer of secure messages to and from a mobile telephone. More specifically, this invention relates to a method of providing encrypted messaging on primitive mobile telephones, such as Series 30 and Series 40 mobile telephones, that may be independent of SMS messaging and that does not require significant amounts of memory on the mobile telephone to operate. This is achieved in part by carefully selecting a suitable encryption algorithm and thereafter optimizing the suitable encryption algorithm code. All encryption and decryption functions may be earned out on the mobile telephone thereby providing enhanced security without requiring external encryption servers. There is further provided a method of providing a suitable encryption algorithm for a mobile telephone.
(FR) L'invention porte sur un procédé et un système de transfert sécurisé de messages à destination ou en provenance de téléphones mobiles. L'invention porte plus spécifiquement sur des procédés donnant à des téléphones mobiles anciens tels que ceux des séries 30 et 40 des possibilités de messagerie indépendantes des messages SMS et qui ne demandent pas de quantités importantes de mémoire dans le téléphone mobile. Cela s'obtient en partie par en sélectionnant soigneusement un algorithme de cryptage puis en optimisant le code adapté dudit algorithme. Toutes les fonctions de cryptage et de décryptage peuvent être récupérées dans le téléphone mobile ce qui améliore la sécurité sans devoir recourir à des serveurs de cryptage. L'invention porte en outre sur un procédé d'élaboration d'un algorithme de cryptage pour téléphone mobile.
