Patent

CA 2421850

The problem of real-time neutralising or revoking of a X509-type certificate, belatedly available in a public database (BD) is solved by directly neutralising (35) in a mobile telephone (1) a sub-programme (26) of signature and/or transmission of certificates concerning transactions to be validated. Thus by doing so neutralisation is achieved in the ten minutes following the signalling, or the neutralisation request, whereas it requires 24 to 48 hours in normal administrative circuits (AE, PB).

On résout un problème de neutralisation ou révocation en temps réel d'un certificat de type X509, disponible tardivement dans une base de données publique (BD), en neutralisant (35) directement dans un téléphone mobile (1) un sous-programme (26) de signature et/ou de transmission de certificats relatifs ô des transactions ô valider. On montre qu'en agissant ainsi on aboutit ô une neutralisation dans les dix minutes qui suivent la signalisation, ou la requête en neutralisation, alors qu'il faut entre 24 et 48 heures dans les circuits administratifs normaux (AE, PB).
