    • Generally, this disclosure describes devices, methods and systems for securely providing context sensor data to mobile platform applications. The method may include configuring sensors to provide context data, the context data associated with a mobile device; providing an application programming interface (API) to a sensor driver, the sensor driver configured to control the sensors; providing a trusted execution environment (TEE) operating on the mobile device, the TEE configured to host the sensor driver and restrict control and data access to the sensor driver and to the sensors; generating a request for the context data through the API, the request generated by an application associated with the mobile device; receiving, by the application, the requested context data and a validity indicator through the API; verifying, by the application, the requested context data based on the validity indicator; and adjusting a policy associated with the application based on the verified context data.
    • 通常,本公开描述了用于向移动平台应用安全地提供上下文传感器数据的设备,方法和系统。 该方法可以包括配置传感器以提供上下文数据,与移动设备相关联的上下文数据; 向传感器驱动器提供应用编程接口(API),所述传感器驱动器被配置为控制所述传感器; 提供在所述移动设备上操作的受信任的执行环境(TEE),所述TEE被配置为托管所述传感器驱动器,并限制对所述传感器驱动器和所述传感器的控制和数据访问; 通过API生成对上下文数据的请求,由与移动设备相关联的应用生成的请求; 通过应用程序接收所请求的上下文数据和通过API的有效性指示符; 根据应用程序,根据有效性指标验证所请求的上下文数据; 以及基于所验证的上下文数据来调整与所述应用相关联的策略。
