摘　　要：上下文相关信息,例如可操作的、用户个人的、空间的、环境的信息能够为用户提供他们确实需要而没有明确表示的服务。利用上下文内容相关的方法分析移动设备提供的用户通话记录、日程表、GPS和用户安装的应用。在收集这几方面信息之后,加以考虑时间和地点的因素,使整个认证过程更有可靠性。提出在移动云计算背景下的上下文相关身份认证框架,并详细描述框架的各个组件及决策器的算法模型和通信协议部分,使用户能够更加方便、安全地使用移动云。Context awareness information, such as the operational, users for the services they really needed without explicit requesting. user＇ s personal, spatial and environmental information, can provide We analyse users＇ call records, calendar, GPS and user installed applications provided by the mobile devices with the method of context awareness. After collecting the information, time and location factors are taken into consideration, which makes the whole authentication process more reliable. We also put forward the context awareness authentication architecture under the background of mobile cloud computing, and give detailed description of each component of the architecture and the algorithm model of the decision-making device as well as the communication protocol, so that the user will use the mobile cloud safer and more convenient.
