Understanding Cryptography

Prof. Dr.-Ing. Christof Paar has the Chair for Embedded Security at the University of Bochum, Germany, and is Adjunct Professor at the University of Massachusetts at Amherst, USA. Prof. Paar has taught cryptography for 15 years to engineering and computer science students in the US and in Europe, and he has taught many industrial practitioners at organizations such as Motorola, Philips and NASA. He has more than 100 publications in applied cryptography and is a cofounder of the Workshop on Cryptographic Hardware and Embedded Systems (CHES), the key academic event in this field.Prof. Dr.-Ing. January Pelzl started his career at Bosch Telecom GmbH. He has a Ph.D. in applied cryptography, and as a researcher he investigated the practical aspects of elliptic-curve-based cryptography and cryptanalysis. He has published extensively about his theoretical and industrial work through leading international conferences and journals, and he has taught many IT security and cryptography courses in industry. He was the Managing Director of "ESCRYPT GmbH" in Bochum. Since January 2015 he is the professor of  "Computer Security" in Hochschule Hamm-Lippstadt.The authors' website (http://www.crypto-textbook.com/) provides extensive notes, slides, video lectures; the authors' YouTube channel (https://www.youtube.com/channel/UC1usFRN4LCMcflV7UjHNuQg) includes video lectures.

From the reviews: "The authors have succeeded in creating a highly valuable introduction to the subject of applied cryptography. I hope that it can serve as a guide for practitioners to build more secure systems based on cryptography, and as a stepping stone for future researchers to explore the exciting world of cryptography and its applications." (Bart Preneel, K.U.Leuven) "The material is very well presented so it is clear to understand. The necessary amount of mathematics is used and complete yet simple examples are used by the authors to help the reader understand the topics. ... [The authors] appear to fully understand the concepts and follow a very good pedagogical process that helps the reader not only understand the different topics but motivate you to perform some of the exercises at the end of each chapter and browse some of the reference materials. I fully recommend this book to any software developer/designer working or considering working on a project that requires security." (John Canessa) "The book presents a panoramic of modern Cryptography with a view to practical applications. ... The book is well written, many examples and figures through it illustrate the theory and the book's website offers links and supplementary information. The book also discusses the implementation in software and hardware of the main algorithms described." (Juan Tena Ayuso, Zentralblatt MATH, Vol. 1190, 2010)
