密碼學(xué)與網(wǎng)絡(luò)安全

內(nèi)容概要

本書清晰易懂地介紹了密碼學(xué)和網(wǎng)絡(luò)安全的基本概念和實際問題，探討了加密、解密、對稱和不對稱密鑰，詳細(xì)分析和解釋了各種主要密碼算法，包括數(shù)據(jù)加密標(biāo)準(zhǔn)（DES），國際數(shù)據(jù)加密算法（IDEA），RC5，Blowfish，選進加密標(biāo)準(zhǔn)（AES），RSA，數(shù)字簽名算法（DSA）等，并討論了主要用于機構(gòu)的防火墻和虛擬專用網(wǎng)絡(luò)（VPN）技術(shù)，數(shù)字簽名，公鑰基礎(chǔ)設(shè)施（PKI）和XML安全性，安全套接協(xié)議層（SSL），安全超文本傳輸協(xié)議（SHTTP），安全電子交易（SET），3D安全，PGP，PEM，S/MIME等。在無線安全方面研究了WAP、GSM、3G、身份認(rèn)證、單點登錄（SSO）等技術(shù)。本書還介紹了拒絕服務(wù)（DoS）攻擊，聯(lián)機銀行交易等一些案例研究。    本書每章后面給出了多項選擇題、復(fù)習(xí)題、編程練習(xí)題等。本書不僅對于普及IT專業(yè)人員的網(wǎng)絡(luò)安全知識、提高普通用戶的安全意識會大有裨益，也是本科生和研究生的一本不錯的參考書。
