About the Book

Inhaltsangabe: Einleitung: Die Informationstechnologie weist neben zahlreichen betriebswirtschaftlichen Anwendungsmöglichkeiten, ebenfalls verschiedene Risiken auf. Diese zeigen sich insbesondere in der Flüchtig- und Manipulierbarkeit elektronischer Daten. Nach verschiedenen Einschätzungen stellt derzeit z. B. das in einem gerichtlichen Verfahren kaum nachweisbare Zustandekommen elektronisch geschlossener Verträge, eine erhebliche Behinderung des elektronischen Handels dar. Durch verschiedene Rechtsanpassungen auf europäischer und nationaler Ebene wurde ein elektronischer Signaturtyp geschaffen, der in Analogie zur eigenhändigen Unterschrift, die Integrität und Authentizität von elektronischen Daten ermöglichen soll. Die Regelungen des Signaturgesetzes beschränken sich hierbei im wesentlichen auf infrastrukturelle und informationstechnische Spezifikationen. Durch Formanpassungen in verschiedenen Bereichen des Privat- und öffentlichen Rechts wurde die qualifizierte elektronische Signatur teilweise zu einem vollwertigen rechtlichen Substitut der eigenhändigen Unterschrift. Die Regelung zur dauerhaften Überprüfbarkeit sowie die Beweiswirkung ist jedoch nicht durchgängig stringent geregelt. Als Basiskonzept dient die Public-Key-Kryptographie unter Einbeziehung einer vertrauenswürdigen Instanz. Hierdurch ist die qualifizierte elektronische Signatur im Vergleich zur Unterschrift deutlich fälschungssicherer. Die Sicherheit der verwendeten Verfahren und Algorithmen ist unter Verwendung entsprechender Parameter sehr hoch. Im Vergleich zu den ausgeprägten Anforderungen an Infrastrukturanbieter existieren im Bereich der Anwender dagegen kaum Sicherheitsbestimmungen, wodurch sich gerade private Nutzer einem gewissen Bedrohungspotential durch sogenannte Trojaner ausgesetzt sehen müssen. Als Ursache für die fehlende Durchsetzung der qualifizierten elektronischen Signatur sind schließlich nicht allein die sich gegenseitig bedingenden Faktoren wie konkurrierende Signaturverfahr
