Cryptography is a key technology in electronic key systems. It is used to keep data secret, digitally sign documents, access control, etc. Therefore, users should not only know how its techniques work, but they must also be able to estimate their efficiency and security. For this new edition, the author has updated the discussion of the security of encryption and signature schemes and recent advances in factoring and computing discrete logarit...

This book constitutes the refereed proceedings of the 11th International Conference on the Theory and Application of Cryptographic Techniques in Africa, AFRICACRYPT 2019, held in Rabat, Morocco, in July 2019. The 22 papers presented in this book were carefully reviewed and selected from 53 submissions. The papers are organized in topical sections on protocols, post-quantum cryptography, zero-knowledge, lattice based cryptography, new schemes a...

Das Internet durchdringt alle Lebensbereiche: Gesundheitsversorgung, Bildung, Unterhaltung, Produktion, Logistik, Verkauf, den Finanzsektor, die öffentliche Verwaltung aber auch kritische Infrastrukturen wie Verkehr, Energieversorgung und Kommunikationsnetze. Kryptographie ist eine zentrale Technik für die Absicherung des Internets. Ohne Kryptographie gibt es im Internet keine Sicherheit. Kryptographie entwickelt sich ständig weiter und ist ei...

The book deals with algorithmic problems related to binary quadratic forms. It uniquely focuses on the algorithmic aspects of the theory. The book introduces the reader to important areas of number theory such as diophantine equations, reduction theory of quadratic forms, geometry of numbers and algebraic number theory. The book explains applications to cryptography and requires only basic mathematical knowledge. The author is a world leader i...

The introduction of public key cryptography (PKC) was a critical advance in IT security. In contrast to symmetric key cryptography, it enables confidential communication between entities in open networks, in particular the Internet, without prior contact. Beyond this PKC also enables protection techniques that have no analogue in traditional cryptography, most importantly digital signatures which for example support Internet security by authen...

A thorough multidisciplinary analysis of various perspectives on internet privacy was published as the first volume of a study, revealing the results of the achatech project "Internet Privacy - A Culture of Privacy and Trust on the Internet." The second publication from this project presents integrated, interdisciplinary options for improving privacy on the Internet utilising a normative, value-oriented approach. The ways in which privacy prom...

Oftmals wird in der Manuellen Medizin oder den verschiedenen Schulen der Osteopathie versucht, eine Primärläsion (d.h. eine dem Störungsbild des Patienten zugrunde liegende Ur-Blockierung oder ein Trauma) zu identifizieren. Die Behandlung der Primärläsion würde dann die Symptome auflösen. Dieser Monokausalität setzten die Autoren einen vielfältigeren Ansatz entgegen: Da Patienten erst beim Entstehen von Schmerz den Arzt aufsuchen, sehen Manual...
