Title
(EN) MOBILE DEVICE AND METHOD FOR PROVIDING CERTIFICATE BASED CRYPTOGRAPHY
(FR) DISPOSITIF MOBILE ET PROCEDE DESTINES A FOURNIR UN CERTIFICAT A BASE CRYPTOGRAPHIQUE
Abstract
(EN)
A mobile device and method for providing certificate based cryptography includes a receiver (102) operative to receive a wireless transmission (110). Included within the wireless transmission is a certificate revocation notification (112). The mobile device and method thereof further includes an authenticator (104) operative to receive the certificate revocation notification (112) and operative to authenticate signed comparison data (120) within the certificate revocation notification (112). Upon authentication, an updater (106) is operative to update data respresenting at least one private or public key (107) based on the certificate revocation notification (112).

L'invention concerne un dispositif mobile et un procédé destinés à fournir un certificat à base cryptographique comprenant un récepteur (102) permettant de recevoir une transmission sans fil (110). Une notification de révocation de certificat (112) est inclus dans la transmission sans fil. Le dispositif mobile et le procédé correspondant comprennent, en outre, un authentificateur (104) permettant de recevoir la notification de révocation de certificat (112) et d'authentifier les données de comparaison signées (120) dans la notification de révocation de certificat (112). Lors de l'authentification, un actualisateur (106) permet d'actualiser les données représentant au moins une clé privée ou publique (107) basée sur la notification de révocation de certificat (112).
