Features: The author's professional background allows him to review many information security systems and cryptographic protocols, some of which are applied in critical scenarios. In many applications, the author observed the presence of so-called "textbook cryptography" features in these systems, which involve directly applying cryptographic algorithms commonly introduced in cryptography textbooks. Encrypting passwords directly using basic public-key encryption algorithms is a typical example of textbook cryptography. The appearance of textbook cryptography with "non-negligible probability" in important application scenarios has caused the author's concern. It seems that the general hazards of textbook cryptography have not been fully recognized by many individuals who design and develop information security systems for critical real-world applications.
Part I provides an introductory overview of cryptography and information security. Part II introduces the mathematical background knowledge for this book, which can also serve as a systematic background for studying the fundamentals of modern cryptography theory. Part III introduces basic cryptographic algorithms and techniques for providing confidentiality and data integrity protection. Part IV covers an important concept in applied cryptography and information security—authentication. Part V rigorously formalizes the strong (practical) security concepts of public-key cryptography technology (encryption, signing, and signcryption) and presents a formalized analysis method for authentication protocols. Part VI includes two technical chapters and a brief commentary. This book is suitable for undergraduate students, security engineers working in high-tech companies on the design and development of information security systems, corporate information security system managers, or software/hardware developers producing security products, as well as Ph.D. students who have just started research in cryptography or computer security.
