The provided outline covers a comprehensive introduction to cryptography, including its overview, mathematical background, and various cryptographic techniques. The book begins with an introduction to cryptography and information security, followed by detailed discussions on functions, basic terminology, and symmetric-key encryption. It then delves into digital signatures, authentication, public-key cryptography, hash functions, protocols, and key management. The mathematical background section covers probability theory, information theory, complexity theory, number theory, and abstract algebra. The book also explores specific cryptographic problems such as integer factorization, the RSA problem, and the discrete logarithm problem. Additionally, it discusses public-key parameters, pseudorandom bits and sequences, stream ciphers, block ciphers, and various encryption schemes. The latter part of the book focuses on digital signatures, identification and entity authentication, key establishment protocols, and key management techniques, providing a detailed analysis of each topic.The provided outline covers a comprehensive introduction to cryptography, including its overview, mathematical background, and various cryptographic techniques.
