免费无线局域网服务，也被称为“免费Wi-Fi”，早已在世界各地广泛部署，以吸引游客和购物者。目前大多数的免费Wi-Fi都是基于开放Wi-Fi和Captive Portal的结合，存在窃听、中间人攻击等诸多安全问题。基于Hotspot 2.0规范的下一代Hotspot（NGH）已被开发为新的概念标准，为公共/免费无线LAN服务带来更高的安全性和可用性。虽然一些运营商已经推出了NGH，但全球免费Wi-Fi漫游系统仍处于近发展阶段。我们已开发NGH试验平台系统，并启动了“Cityroam”，这是一项具有国际漫游功能的安全免费Wi-Fi试点服务。Cityroam旨在连接尽可能多的漫游系统，并为研究和教育机构集成eduroam漫游系统。本文介绍了Cityroam的体系结构概述，特别是它的信任和服务设计。该系统的有效性已通过试点服务和城市Wi-Fi漫游试验得到证实，该试验涉及许多电信和Wi-Fi运营商。
Free Wireless LAN services, also known as “Free Wi-Fi,” have long been widely deployed all over the world for attracting tourists as well as shoppers. Most of the Free Wi-Fi today are based on the combination of open Wi-Fi and Captive Portal, and have a lot of security problems such as eavesdropping and Man-in-the-Middle attacks. Next Generation Hotspot (NGH), based on the Hotspot 2.0 specification, has been developed as a new conceptual standard that brings higher security and usability to Public/Free Wireless LAN services. Although some operators have already introduced NGH, world-wide roaming system for Free Wi-Fi is still in a nearly stage of development. We have developed an NGH testbed system and started “Cityroam” which is a pilot service of secured Free Wi-Fi with international roaming capabilities. Cityroam aims at connecting as many roaming systems as possible and also integrating eduroam the roaming system for research and education institutions. This paper presents the architecture overview of Cityroam and, in particular, its trust and service designs. The effectiveness of the system has been confirmed through the pilot service and the City Wi-Fi Roaming trial involving a lot of telecom and Wi-Fi operators.
