Abstract: In this paper presents an enhancement to the encryption function of RC5 algorithm which addresses the poor bit propagation or avalanche effect in the early rounds of the algorithm. This ...
Chiffre par blocs à arguments, taille de blocs, taille de clé et nombre de rondes variables. Dans le RC5, le chiffrement du message repose sur la division du texte clair en blocs de taille égale, puis ...

ABSTRACT: Frequency Hopping Spread Spectrum (FHSS) system is often deployed to protect wireless communication from jamming or to preclude undesired reception of the signal. Such themes can only be ...
Combien de temps faut-il pour casser une clef de cryptage de 64 bits ' Quatre ans ! C'est le temps qu'on mis 331 252 machines à casser une clé RC5-64 permettant de décoder un message crypté pour ...
ABSTRACT: A security protocol is used to ensure the messages transferred over a network free from attack. The CCM security operation mode adopts CTR, and CBC-MAC schemes to implement message ciphering ...
