Abstract

Die Erfindung betrifft ein Verfahren zur Authentifizierung digitaler Daten, bei welchem die digitalen Daten mit einem zweiteiligen Schlüssel verknüpft werden. Beim Authentifizierungsvorgang werden die beiden Teilschlüssel zu einem Referenzschlüssel kombiniert, dessen Übereinstimmung mit einem den digitalen Daten zugeordneten Hauptschlüssel überprüft wird. Nach erfolgreicher Authentifizierung wird der Hauptschlüssel und einer oder beide Teilschlüssel für ungültig erklärt und es werden neue aktualisierte Schlüssel erzeugt. Danach ist eine weitere Authentifizierung der digitalen Daten nur mittels des aktualisierten Datensatzes möglich. Das erfindungsgemäße Authentifizierungsverfahren eignet sich insbesondere zur automatisierten Durchführung einer Internet-Tauschbörse.
