Grundlagen kooperativer Anonymisierungsnetze

Jens Oberender myPHD, Doktoranden-Workshop Institut für IT-Sicherheit und Sicherheitrecht, Universität Passau, 2009 Unverkettbare Nachrichten sind ein Grundbaustein anonymer Kommunikation. Anonymisierungsnetze schützen mittels Unverkettbarkeit, wer mit wem kommuniziert sowie die Identität der Beteiligten einer Kommunikationsbeziehung. Anonymisierungsnetze benötigen Kooperation, da die Anonymität … Continue reading

Denial-of-Service Flooding Detection in Anonymity Networks

Jens O. Oberender, Melanie Volkamer und Hermann De Meer IEEE Workshop on Monitoring, Attack Detection and Mitigation (MonAM) 2007 Denial-of-Service (DoS) flooding attackers benefit from sender anonymity and exit node diversity. Anonymity networks provide this by hiding the communication relationship and therefore hinder attack detection. After … Continue reading
