CA 2555322

A cryptosystem prevents replay attacks within existing authentication protocols, susceptible to such attacks but containing a random component, without requiring modification to said protocols. The entity charged with authentication maintains a list of previously used bit patterns, extracted from a portion of the authentication message connected to the random component. If the bit pattern has been seen before, the message is rejected; if the bit pattern has not been seen before, the bit pattern is added to the stored list and the message is accepted.

L'invention concerne un système de chiffrement permettant de prévenir des attaques par réinsertion dans des protocoles d'authentification existants, sujets à de telles attaques mais qui contiennent un composant aléatoire, ce système ne nécessitant aucune modification desdits protocoles. L'entité chargée de l'authentification tient à jour une liste de motifs de bits utilisés précédemment, extraits d'une partie du message d'authentification liée au composant aléatoire. Si le motif de bits a été détecté auparavant, le message est rejeté ; si le motif de bits n'a pas été détecté auparavant, celui-ci est ajouté à la liste mémorisée et le message est accepté.
