Features: The study and application of cryptography have a history of thousands of years, but as a science, it began in the 1950s. It is undeniable that the widespread use of the internet has greatly promoted the research and development of cryptography. Most countries and regions have established cryptography societies, which regularly hold academic conferences for academic exchange, thereby promoting the research and application of cryptography. A large number of books on cryptography have been published domestically and internationally, and its theoretical research is relatively mature, with consensus reached on many issues. Douglas R. Stinson's book "Cryptography: Theory and Practice (Second Edition)" is a distinctive textbook, characterized by the following aspects:
1. Clear Presentation. The language in the book is simple and easy to understand. For example, differential and linear cryptanalysis of block ciphers are inherently difficult to describe, but the book presents them very clearly.
2. Rigorous Arguments. The book provides strict mathematical proofs for many cryptographic problems, such as unique decryption distance and the extendability criterion for hash functions, exhibiting a logical elegance.
3. Novel Content. The book offers clear discussions on many cryptographic problems, especially public-key cryptography, from the perspective of provable security. It uses the term "oracle" and helps readers grasp the essence of this concept through reading. The book also briefly introduces some recent developments in the field of cryptography.
4. Well-Chosen Materials. The book selects a large number of typical and relatively mature materials, making it particularly suitable for teaching purposes.
5. Abundant Exercises. By practicing the carefully arranged exercises at the end of each chapter, readers can quickly and skillfully master the basic techniques of cryptography.
This book is a classic in the field of cryptography and has been used as a prescribed textbook by universities worldwide. Based on the first edition, the book has been meticulously and rigorously revised, focusing on the core issues of cryptographic research. It systematically elaborates on cryptography from the perspective of applied discrete mathematics. The book is divided into 7 chapters, starting with classical cryptography, then introducing Shannon's information theory and its application in cryptography, followed by modern cryptography, covering encryption techniques, the Data Encryption Standard (DES), the Advanced Encryption Standard (AES), public-key cryptography, one-way hash functions, digital signatures, and more. In terms of content selection, it emphasizes both breadth and in-depth exploration of key points. The book adopts an "learn and apply" approach to teaching mathematical background knowledge, organically integrating fundamental concepts with algorithm descriptions to provide readers with a deeper and more precise understanding of algorithms. At the same time, the definitions, theorems, lemmas, and proofs are all clearly explained, allowing readers to fully appreciate the logical elegance. Each chapter is accompanied by a large number of exercises, which not only help readers summarize and apply the book's content but also challenge their interest, thinking, and intelligence.
This book is suitable as a textbook or teaching reference for cryptography courses in computer science, mathematics, and related disciplines. It is also an excellent reference book for cryptographic research.
