Public-Key-Infrastrukturen in einer Peer-to-Peer-Umgebung
نویسندگان
چکیده
Der Einsatz von Peer-to-Peer (P2P) Netzwerken verspricht im Vergleich zu Client-Server-Netzwerken eine bessere Skalierbarkeit, niedrigere Betriebskosten, die Nutzung bislang unausgelasteter Ressourcen und höhere Fehlertoleranz. Eine wichtige Eigenschaft von P2P-Netzwerken ist der Verzicht auf zentrale, vertrauenswürdige Instanzen. Die Realisierung einer Public-Key-Infrastruktur (PKI) basierend auf modernen P2P-Techniken erfordert deswegen besondere Sicherheitsmaßnahmen. Es ist das Ziel dieser Arbeit, die Vorteile einer P2P basierten PKI vorzustellen und geeignete Sicherheitsmechanismen zu präsentieren.
