Quantum computers will break today's most popular public-key cryptographic systems, including RSA, DSA, and ECDSA. This book introduces the reader to the next generation of cryptographic algorithms, the systems that resist quantum-computer attacks: in particular, post-quantum public-key encryption systems and post-quantum public-key signature systems. Leading experts have joined forces for the first time to explain the state of the art in quantum computing, hash-based cryptography, code-based cryptography, lattice-based cryptography, and multivariate cryptography. Mathematical foundations and implementation issues are included. This book is an essential resource for students and researchers who want to contribute to the field of post-quantum cryptography.

Aus den Rezensionen zur 2. Auflage: ?Diese von einem Mathematiker geschriebene ?Einf?hrung in die Kryptographie" f?llt sofort durch ihren pr?zisen und logisch einwandfreien Stil auf. Die verwendeten Begriffe (Verschl?sselungsverfahren, perfekte Sicherheit, Hashfunktion, ...) werden mathematisch sauber und kurz definiert, und es wird sehr wohl unterschieden, was ?bewiesen" ist [...] und was ?allgemeiner Glaube der Experten" ist. Trotz dieser mathematischen Genauigkeit ist dieses Buch insbesondere f?r Anf?nger und speziell auch f?r Nicht-Mathematiker sehr verst?ndlich gehalten. Das n?tige mathematische Werkzeug (Restklassenringe, Matrizen und lineare Abbildungen, Wahrscheinlichkeit, Erzeugung von Primzahlen, Faktorisierungsverfahren, Ausblick auf elliptische Kurven) wird vor der jeweiligen Anwendung vorgestellt. Dann wird der Themenkreis pr?gnant, sehr verst?ndlich und mit Beispielen illustriert, besprochen, wobei der Ge?bte die dahinterliegende mathematische Idee schnell erkennen kann. Dabei werden im Wesentlichen alle Basistechniken der modernen Kryptographie erfasst. Soweit m?glich bzw. ?blich, wird das englische Fachvokabular der Kryptographie in die deutsche Sprache ?bersetzt. Ich hoffe, dass die Freude des Rezensenten beim Lesen dieses Buches auch von vielen anderen Lesern ebenfalls empfunden werden kann." (Int. Math. Nachrichten 2002, Vol 56, Issue 189). ?[...] ?Klein, aber fein" ist das Charakteristikum des Buches: Jeder Abschnitt ist mit (f?r Mathematiker) sehr anschaulichen Beispielen und kleinen ?bungsaufgaben versehen. Entwickler finden hier eine reiche Quelle der Hintergr?nde, die sie f?r eine Implementation wissen m?ssen." (Amazon.de-Redaktion)

Threedecadesagopublic-keycryptosystemsmadea revolutionarybreakthrough in cryptography. They have developed into an indispensable part of our m- ern communication system. In practical applications RSA, DSA, ECDSA, and similar public key cryptosystems are commonly used. Their security depends on assumptions about the di?culty of certain problems in number theory, such as the Integer Prime Factorization Problem or the Discrete Logarithm Problem. However, in 1994 Peter Shor showed that quantum computers could break any public-key cryptosystembased on these hard number theory problems. This means that if a reasonably powerful quantum computer could be built, it would put essentially all modern communication into peril. In 2001, Isaac Chuang and NeilGershenfeldimplemented Shor'salgorithmona7-qubitquantumcomputer. In 2007 a 16-qubit quantum computer was demonstrated by a start-up company with the prediction that a 512-qubit or even a 1024-qubit quantum computer would become available in 2008. Some physicists predicted that within the next 10 to 20 years quantum computers will be built that are su?ciently powerful to implement Shor's ideas and to break all existing public key schemes. Thus we need to look ahead to a future of quantum computers, and we need to prepare the cryptographic world for that future.

The recent development of quantum computing and quantum algorithmics has raised important questions in cryptography. With Shor s algorithm (Peter W. Shor, Polynomial-TimeAlgorithms for Prime Factorization and Discrete Lo- rithmsonaQuantumComputer, SIAMJ.Sci.Statist.Comput.41(2):303-332, 1999)thecollapseofsomeofthemostwidelyusedtechniquesfor securingdigital communications has become a possibility. In consequence, the everlasting duty of the cryptographic research community to keep an eye on alternative te- niques has become an urgent necessity. Post-quantum cryptography was born. Its primary concern is the study of public-key cryptosystems that remain - cure in a world with quantum computers. Currently, four families of public-key cryptosystemsseemto havethis potential: code-based, hash-based, lattice-based and multivariate public-key cryptosystems. Other techniques may certainly join this rapidly growing research area. With the PQCrypto conference series, this emerging community has created a place to disseminate results, exchange new ideas and de?ne the state of the art. In May of 2006, the First International Workshop on Post-Quantum Cryptography was held at the Katholieke Univ- siteit Leuvenin Belgium with support fromthe EuropeanNetworkof Excellence ECRYPT.TheSecondInternationalWorkshoponPost-QuantumCryptography, PQCrypto2008, washeldattheUniversityofCincinnati, USA, inOctober2008."

Die Kommunikation über das Internet ist quasi öffentlich: Dritte können Nachrichten mitlesen, abfangen oder fälschen. Genauso kann ein Sender einer Nachricht behaupten, diese nie gesendet zu haben, und ein Empfänger kann behaupten, eine Nachricht nie erhalten zu haben. Abhilfe schafft die Kryptografie. Sie ermöglicht nicht nur die Verschlüsselung von Nachrichten, sondern auch digitale Unterschriften, die Authentifizierung und die Anonymisierung von Kommunikationspartnern. Das hier vorliegende Buch ist eine Einführung in die Kryptografie für Studierende - von der symmetrischen über die asymmetrische Verschlüsselung bis hin zu Hash-Funktionen. Umfassend, keinesfalls oberflächlich, aber ohne Vorwissen verständlich.
