PDF版本的。 The first part consists of the following material: Chapter 1 is a fairly elementary introduction to simple “classical” cryptosystems. Chapter 2 covers the main elements of Shannon’s approach to cryptography, including the concept of perfect secrecy and the use of information theory in cryptography. Chapter 3 is a lengthy discussion of the Data Encryption Standard; it includes a treatment of differential cryptanalysis. The second part contains the following material: Chapter 4 concerns the RSA Public-key Cryptosystem, together w ith a considerable amount of background on number-theoretic topics such as primality testing and factoring. Chapter 5 discusses some other public-key systems, the most important being the ElGamal System based on discrete logarithms. Chapter 6 deals with signature schemes, such as the Digital Signature Standard, and includes treatment of special types of signature schemes such as undeniable and fail-stop signature schemes. The subject of Chapter 7 is hash functions. Chapter 8 provides an overview of the numerous approaches to key distribution and key agreement protocols. Finally, Chapter 9 describes identification schemes. The third part contains chapters on selected research-oriented topics, namely, authentication codes, secret sharing schemes, pseudo-random number generation, and zero-knowledge proofs。。。
