Cryptology: Classical and Modern with Maplets (Hardcover)

Easily Accessible to Students with Nontechnical Backgrounds
In a clear, nontechnical manner, Cryptology: Classical and Modern with Maplets explains how fundamental mathematical concepts are the bases of cryptographic algorithms. Designed for students with no background in college-level mathematics, the book assumes minimal mathematical prerequisites and incorporates student-friendly Maplets throughout that provide practical examples of the techniques used.

Technology Resource
By using the Maplets, students can complete complicated tasks with relative ease. They can encrypt, decrypt, and cryptanalyze messages without the burden of understanding programming or computer syntax. The authors explain topics in detail first before introducing one or more Maplets. All Maplet material and exercises are given in separate, clearly labeled sections. Instructors can omit the Maplet sections without any loss of continuity and non-Maplet examples and exercises can be completed with, at most, a simple hand-held calculator. The Maplets are available for download at www.radford.edu/~npsigmon/cryptobook.html.

A Gentle, Hands-On Introduction to Cryptology
After introducing elementary methods and techniques, the text fully develops the Enigma cipher machine and Navajo code used during World War II, both of which are rarely found in cryptology textbooks. The authors then demonstrate mathematics in cryptology through monoalphabetic, polyalphabetic, and block ciphers. With a focus on public-key cryptography, the book describes RSA ciphers, the Diffie–Hellman key exchange, and ElGamal ciphers. It also explores current U.S. federal cryptographic standards, such as the AES, and explains how to authenticate messages via digital signatures, hash functions, and certificates.

易於非技術背景學生理解
以清晰、非技術性的方式，《Cryptology: Classical and Modern with Maplets》解釋了基本數學概念如何成為密碼算法的基礎。本書針對沒有大學程度數學背景的學生設計，假設學生對數學的先備知識很少，並且在全書中使用了學生友好的Maplets，提供了實際的技巧示例。

技術資源
通過使用Maplets，學生可以相對輕鬆地完成複雜的任務。他們可以在不需要理解編程或計算機語法的負擔下，對消息進行加密、解密和密碼分析。作者在介紹一個或多個Maplets之前，首先詳細解釋了相關主題。所有的Maplet材料和練習都在單獨的、清晰標記的部分中提供。教師可以省略Maplet部分而不會有任何連續性的損失，非Maplet的示例和練習最多只需要一個簡單的手持計算器即可完成。Maplets可以在www.radford.edu/~npsigmon/cryptobook.html上下載。

溫和、實踐性的密碼學入門
在介紹基本方法和技巧之後，本書全面展開了二戰期間使用的Enigma密碼機和Navajo密碼，這兩者在密碼學教材中很少見。然後，作者通過單字母替換、多字母替換和分組密碼來展示密碼學中的數學。本書重點介紹了公鑰密碼學，描述了RSA密碼、Diffie-Hellman密鑰交換和ElGamal密碼。它還探討了當前美國聯邦密碼標準，如AES，並解釋了如何通過數字簽名、哈希函數和證書來驗證消息。
