Aus den Rezensionen: "... Der ... vorliegende Sammelband enthalt 25 ausgewahlte wissenschaftliche Arbeiten ... Young und Yung prasentieren ... ein Anwendungskonzept, das eine asymmetrische Verschlusselung aufgrund eines moglicherweise absichtlich falschen offentlichen Schlussels unbeweisbar machen soll. Bodenstandiger geht es da schon zu, wenn Chakinala und seine Kollegen sich der steganografischen Kommunikation uber einen geordneten Kanal widmen - das TCP-Protokoll als Medium fur den geheimen Informationskanal gibt ein einleuchtendes Beispiel. Wegweisend ist der Beitrag von Bergmair und Katzenbeisser zu inhaltssensitiver Steganografie ..." (Tobias Engler/fm, in: c't - Magazin fur Computer-Technik, 2007, Issue 26, S. 218)
