Features: This book introduces the knowledge of cryptography from three aspects: The first part introduces classic problems in classical cryptography, including monoalphabetic encryption, affine encryption, polyalphabetic encryption, polygraphic encryption, and transposition encryption; the second part introduces modern cryptography, including stream encryption, block encryption, and public-key encryption; the third part introduces the future of cryptography and provides a brief introduction to quantum cryptography. A prominent feature of this book is its detailed description of cryptanalysis, enabling readers to grasp the internal algorithms of encryption while also understanding the weaknesses of various encryption methods. Accompanying the book is the CAP software, which implements various encryption methods, allowing readers to use it for encryption and decryption, thereby enhancing the scientific and applicability of the book. Review questions are provided at the end of each chapter, offering readers great inspiration and imagination. This book is not only an excellent textbook on cryptography but also an invaluable reference for cryptography researchers and enthusiasts alike.
