《网络安全导论 理论与实践（英文版）》基于网络安全的新研究成果，全面系统地向读者介绍了网络安全的全貌，从理论到实践围绕两条主线展开，一条主线是计算机密码学的标准算法与网络安全协议，另一条主线是计算机系统与网络设备的安全设置与防护。两条主线相互交织，构成网络通信的安全防护网。

本书内容包括网络安全攻防概貌、标准加密算法、密钥产生算法、公钥加密算法、密钥管理算法、身份认证算法、网络各层安全协议、无线网络安全协议、云计算与云存储安全协议、网络防火墙原理、入侵检测系统以及恶意软件防护技术。此外，每章还附有大量习题，包括许多读者亲身经历过的网络安全攻击，帮助读者从实例中好地掌握网络安全的原理和应用。

本书可作为高等学校计算机、电子与通信以及信息安全学科高年级本科生和研究生教材，也可供其他专业研究生、相关行业的专业研究人员、安全专家以及工程师参考。
