Content Features: This book keeps pace with technological advancements and meets the needs of teaching reform. It explains the fundamental knowledge of cryptography in an accessible and modular manner, covering both the key and challenging aspects of the field. The content is divided into two aspects: On one hand, it introduces cryptographic theory, providing detailed descriptions and analyses of common cryptographic algorithms. On the other hand, it highlights the practical applications of cryptography, offering case studies of typical cryptographic algorithms used in current information processing and transmission. It establishes the basic architecture of cryptographic algorithm application systems and conducts a detailed analysis and description of potential performance issues that may arise in practical applications, serving as a valuable reference for cryptographic research and application development. Writing Style: The book is well-structured, with clear priorities, logical coherence, and complementary content such as key points, summaries, and practical exercises in each chapter. This enables readers to fully grasp the fundamental knowledge of cryptography while mastering its application techniques, allowing them to quickly apply these skills in real-world scenarios, thereby achieving a harmonious balance between teaching and learning. Target Audience: This book can serve as a teaching resource for undergraduate students in computer science and technology, network engineering, information security, and related fields at universities. It is also an excellent reference for enthusiasts interested in self-studying and applying cryptographic techniques. Based on the training objectives and basic requirements of higher education institutions, as well as the author's extensive teaching experience and engineering practice, this book has been developed to implement teaching reform, making cryptographic technology more application-oriented. It provides a foundational textbook for cryptographic technology. After introducing the basic concepts and classifications of cryptography, the book covers widely used cryptographic techniques. The content is divided into two aspects: On one hand, it introduces cryptographic theory, providing detailed descriptions and analyses of common cryptographic algorithms such as DES, RSA, IDEA, and AES to facilitate the analysis, design, and application of cryptographic algorithms. On the other hand, to emphasize practical applications, it conducts case studies of typical cryptographic algorithm applications in current information processing and transmission, such as digital signatures, identity recognition, and electronic currency. It establishes the basic architecture of cryptographic algorithm application systems and provides a detailed analysis and description of potential performance issues that may arise in practical applications, serving as a valuable reference for cryptographic research and application development. At the end of each chapter, theoretical consolidation questions and hands-on practice exercises are provided to achieve a unified balance between teaching and learning. The book is written in an easy-to-understand language, with rich and detailed content, emphasizing a case-centered approach. It can serve as a teaching resource for undergraduate students in computer science and technology, network engineering, information security, and related fields, as well as a reference for enthusiasts interested in self-studying and applying cryptographic techniques.
