Title (EN) METHOD FOR REFRESHING A PAIRWISE MASTER KEY
(FR) PROCEDE DE RAFRAICHISSEMENT DE CLE MAITRESSE PAR PAIRE
Abstract:
(EN) The present invention provides a method for communication involving a supplicant, an authenticator, and an authentication server having an established security association based on a first key. The supplicant and the authenticator also have an established security association based on a second key. The method may include modifying the second key using the first key in response to determining that a challenge response from the supplicant is valid.
(FR) La présente invention concerne un procédé de communication impliquant un demandeur, un authentificateur, et un serveur d'authentification disposant d'une association de sécurité établie reposant sur une première clé. Le demandeur et l'authentificateur disposent également d'une association de sécurité établie reposant sur une deuxième clé. Le procédé consiste alors à modifier la deuxième clé au moyen de la première clé après constatation de la validité d'une réaction de défit faite par le demandeur.
