Secure Roaming in 802.11 Networks 是一本专著,由 Paul Goransson 和 Raymond Greenlaw 合著,关注于无线局域网(WLAN)的安全漫游技术。随着Wi-Fi技术的普及和移动设备的广泛使用,确保用户在不同接入点之间的无缝切换(漫游)同时保持数据安全成为了一个重要的议题。802.11标准系列是Wi-Fi技术的核心,但正如描述中所言,当前关于漫游的标准化并未达到成熟阶段,因此本书反映了业界对这一领域的最新进展和挑战。 书中详细探讨了如何在802.11网络环境中实现安全漫游,可能涉及的内容包括: 1. **802.11标准的漫游机制**:802.11协议的第2版(802.11i)引入了WPA(Wi-Fi Protected Access)和WPA2(Wi-Fi Protected Access 2),它们提供了加密措施,以保护数据在漫游过程中的传输安全。然而,随着后续版本如802.11r(快速漫游)的出现,作者可能会分析这些版本在漫游性能和安全性上的改进。 2. **漫游过程中身份验证与密钥管理**:如何在用户从一个接入点切换到另一个时,保证身份验证的一致性和密钥的有效性,避免中间人攻击和数据泄露,是书中关注的重点。 3. **安全协议的演进**:随着TLS/SSL、EAP-TLS等协议的应用,作者可能会讨论如何通过这些高级安全协议增强漫游过程中的数据加密和完整性。 4. **漫游策略与优化**:针对不同的应用场景(如企业网络、公共热点等),书中可能提供了实用的漫游策略,以及如何调整参数以提高漫游效率和用户体验。 5. **安全漫游的未来趋势与挑战**:鉴于Wi-Fi标准的持续发展和物联网(IoT)设备的增长,作者可能会展望未来可能出现的新威胁和应对策略,如设备认证、设备间漫游协调等。 6. **实践案例与最佳实践**:书中可能包含实际案例分析,以及针对企业网络管理员和开发者提供的实用建议,帮助读者理解和应用安全漫游的相关技术和解决方案。 由于版权原因,复制或传播本书的部分内容需获得出版商Elsevier的许可。为了获取更具体的信息或获取许可,请联系Elsevier Science & Technology Rights Department。Secure Roaming in 802.11 Networks 是一本紧跟Wi-Fi技术发展前沿,为理解和解决安全漫游问题提供宝贵参考资料的著作。
