Methods and apparatus for enhanced CMEA, or ECMEA, processing. A forward ECMEA and a reverse ECMEA process are provided. The forward ECMEA process decrypts text encrypted by the reverse ECMEA process and the reverse ECMEA process decrypts text encrypted by the forward ECMEA process. The forward ECMEA process employs a first transformation, an iteration of the CMEA process, and a second transformation. The reverse ECMEA process employs a first inverse transformation, an iteration of the CMEA process, and a second inverse transformation. The transformations and inverse transformations, and the iterations of the CMEA process, employ secret offsets to improve security. The transformations and the iteration of the CMEA process also employ an enhanced tbox function using an involuntary lookup table.

L'invention concerne des procédés et un appareil de traitement d'algorithmes de cryptage de messages cellulaires (CMEA) ou d'algorithmes améliorés de cryptage de messages cellulaires(ECMEA). Un processus ECMEA vers l'avant décrypte un texte crypté par un processus ECMEA inverse et ce processus ECMEA inverse décrypte le texte crypté par le processus ECMEA vers l'avant. Le processus ECMEA vers l'avant utilise une première transformation, une itération du processus CMEA, et une deuxième transformation. Le processus ECMEA inverse utilise une première transformation inverse, une itération du processus CMEA, et une deuxième transformation inverse. Les transformations et les transformations inverses, et les itérations du processus CMEA utilisent des décalages secrets pour améliorer la sécurité. Les transformations et l'itération du processus CMEA utilisent également une fonction de bloc amélioré faisant appel à une table de validation involontaire.
