... I think this book is a very inspiring book on cryptography. It goes beyond the traditional topics (most of the cryptosystems presented here are first time in a textbook, some of Paturi's work is not published yet). This way the reader has the feeling how easy to suggest a cryptosystem, how easy to break a safe looking system and hence how hard to trust one. The interested readers are forced to think together with ther researchers and feel the joy of discovering new ideas. At the same time the importance of hardcore mathematics is emphasized and hopefully some application driven students will be motivated to study theory.

... Overall, the book is highly recommended to everyone who has the requisite mathematical sophistication.

... Der Autor, der ... vielen Lesern dieses Rundbriefs gut bekannt sein wird, hat hier ein kleines Werk vorgelegt, das man wohl am Besten als Lesebuch zu algebraischen Aspekten der Kryptographie mit oeffentlichem Schlussel charakterisieren kann. ...
Mit zunehmender Schwierigkeit des Material werden die Ausfuhrungen dabei skizzenhafter und beschranken sich immer starker auf den Hinweis auf entsprechende Quellen, was den Charakter eines guten Lesebuchs, wie ich es oben bezeichnet habe, ausmachen sollte. Das Buch eignet sich damit selbst fur advanced undergraduates, wie es im Klappentext heisst, als Einstieg und erster UEberblick uber ein Gebiet, in dem sich in den letzten Jahren auf uberraschende Weise praktische Anwendungsmoeglichkeiten fur tief innermathematische Themen ergeben haben.

... Es gelingt Koblitz, anschaulich und mit elementaren Mitteln auch Dinge zu erlautern, die in vergleichbaren Texten kaum zu finden sind: z.B. den Hilbertschen Basis- und Nullstellensatz, sowie Groebnerbasen. ...
