Title
(EN) METHOD AND APPARATUS FOR HIGH SPEED BLOCK CIPHERING OF PACKET DATA
(FR) PROCEDE ET SYSTEME DE CHIFFREMENT BLOC RAPIDE DE DONNEES EN PAQUETS
Abstract
(EN)
A system and method for encrypting blocks of plain text. Output FIFO memories are provided for decoupling pseudorandom vector generation from plain text encryption. The output FIFOs produce the effect of multiplexing several cryptographic devices together and can be combined with feedback FIFO memories in order to provide key agility and parallel secret key encryption. Throughput is also enhanced by constructing wide codebooks so that a block of data can be enciphered as a whole.
(FR)
Système et procédé pour chiffrer des blocs de texte en clair. Des mémoires FIFO (premier entré premier sorti) de sortie sont prévues pour séparer la génération de vecteurs pseudo-aléatoires du chiffrement de texte en clair. Les mémoires FIFO de sortie ont pour effet de multiplexer plusieurs dispositifs de chiffrement ensemble et peuvent être combinées avec des mémoires FIFO de réaction afin d'assurer une agilité de clé et un chiffrement parallèle par clé secrète. La capacité de traitement est également améliorée par l'élaboration de larges dictionnaires du chiffre, de sorte qu'un bloc de données peut être chiffré dans son ensemble.
