商品描述
本書闡述了密碼學的發展歷史,重點介紹了密碼學的基本概念、基本理論和基本方法以及常用具體算法。首先,本書對密碼學所需的數論、抽象代數和信息論等預備知識進行了詳細敘述,並介紹了非對稱密碼體制(公鑰密碼學)中的經典算法RSA、Elgamal、Rabin、Diffie–Hellman密鑰交換協議等。在此基礎上,依次介紹了安全通信要用到的對稱密碼(分組密碼和流密碼)與散列函數及其常用算法和分析方法。後,本書以一半的篇幅詳細介紹了安全通信所涉及的公鑰密碼學新成果,包括橢圓曲線密碼、超橢圓曲線密碼、雙線性對密碼、格密碼等,並簡要介紹了安全與鑒別密碼協議。本書可作為密碼學和信息安全方向的本科生和研究生教材,也可供密碼學和信息安全方向的廣大科技工作者參考。
