Block ciphers encrypt blocks of plaintext, messages, into blocks of ciphertext under the action of a secret key, and the process of encryption is reversed by decryption which uses the same user-supplied key. Block ciphers are fundamental to modern cryptography, in fact they are the most widely used cryptographic primitive – useful in their own right, and in the construction of other cryptographic mechanisms.
In this book the authors provide a technically detailed, yet readable, account of the state of the art of block cipher analysis, design, and deployment. The authors first describe the most prominent block ciphers and give insights into their design. They then consider the role of the cryptanalyst, the adversary, and provide an overview of some of the most important cryptanalytic methods.
The book will be of value to graduate and senior undergraduate students of cryptography and to professionals engaged in cryptographic design. An important feature of the presentation is the authors' exhaustive bibliography of the field, each chapter closing with comprehensive supporting notes.
商品描述(中文翻譯)
區塊密碼將明文（plaintext）消息加密為密文（ciphertext）區塊，這一過程是在秘密金鑰的作用下進行的，而加密過程則通過使用相同的用戶提供金鑰的解密（decryption）來逆轉。區塊密碼是現代密碼學的基礎，事實上，它們是最廣泛使用的密碼學原語（cryptographic primitive）——不僅在自身的應用中有用，還在其他密碼學機制的構建中發揮著重要作用。
在本書中，作者提供了一個技術上詳細但易於閱讀的區塊密碼分析、設計和部署的最新狀態介紹。作者首先描述了最突出的區塊密碼，並深入探討其設計。接著，他們考慮了密碼分析師（cryptanalyst）和對手（adversary）的角色，並提供了一些最重要的密碼分析方法的概述。
本書對於研究生和高年級本科生的密碼學學習以及從事密碼設計的專業人士將具有價值。演示的一個重要特點是作者對該領域的詳盡參考書目，每章結尾都有全面的支持性註釋。
