摘要:随着移动办公以及跨地区、跨单位合作的需求不断增加，建筑协同设计也必然将从小范围的局域网拓展到广域网中。而更加开放的环境无疑对安全性与适用性提出了更高的要求。由此，本文针对搭建广域网建筑协同设计平台中的两项关键技术——用户的安全登录与协同方式进行了讨论。对目前流行的域账户登录、单点登录、指纹识别、USBKEY等多种登录方式从技术与应用层面上进行了分析与比较。另一方面，探讨了构建协同设计平台的架构方式，并对其中可能涉及的远程控制等技术进行了可行性分析。最后，结合信息技术的发展趋势，给出了现阶段的解决方案，并对未来的建筑协同设计平台进行了展望。

Abstract: As there is an increasing demand for mobile officing, trans-regional and cross-unit cooperation, building collaborative design is bound to expand from small scale local area network to wide area network. Undoubtedly, a more open environment puts forwards a higher requirement for the security and applicability. As a result, this paper discusses two key technologies on building collaborative design platform in wide area network-User Login Security and Collaborative Framework. On one hand, the author analyzes and compares current popular user login security modes such as domain logon, single sign-on, fingerprint identification and USBKEY from the technical to application level. On the other hand, the author discusses the structure of the framework on building collaborative design platform and makes a feasibility analysis on the technology involved, like remote control. Finally, integrating the trend of information technology development, the author provides a present solution and a future solution of building collaborative design platform in the wide area network.
