Foreword---A. Salomaa
"The present book treats an up-to-date subject from a mathematical point of view. … The entire work is presented at a high level and has a very good and well proved mathematical background … making the book a kind of a reference volume to applied mathematics in cryptography, coding theory and information security for students having basic knowledge and wanting a thorough account of this area, or for developers wanting to understand the mathematical background of the algorithms used in authentication systems." (Ion Iancu, Zentralblatt MATH, Vol. 1157, 2009)
