In a franking system, a postal security device (PSD) is used to account for postage dispensation, and generate digital signatures for inclusion in postage indicia to authenticate same. In accordance with the invention, the PSD includes multiple crypto processors which participate in franking transactions and generate the digital signatures in a multiplexed manner. Each crypto processor verifies the accounting of postage dispensation leading to and including the transactions in which the crypto processor participates. In addition, the crypto processors re-create transaction records and store them therein in a distributed manner.
Dans un système d'affranchissement (100), on utilise un dispositif postal de sécurité (PSD) (110) destiné à comptabiliser la distribution postale, et générer une signature (738) numérique de façon à l'inclure dans la marque d'affranchissement et à authentifier cette dernière. Selon cette invention, ce PSD (110) comprend de multiples processeurs (225-1, 225-2, ... 225-N) de cryptage qui participent aux transactions d'affranchissement et génèrent les signatures (738) numériques en multiplex. Chaque processeur (225-1, 225-2, ... 225-N) de cryptage vérifie la comptabilisation de la distribution postale conduisant aux transactions (et les incluant) auxquelles ce processeur (225-1, 225-2, ... 225-N) de cryptage participe. Ces processeurs (225-1, 225-2, ... 225-N) de cryptage recréent en outre les enregistrements de transaction et les stockent en mémoire de façon répartie (745).
