    • A computing platform (20) is adapted for secure use of trusted user input. The computing platform (20) comprises a user input device (14), a first isolated operating environment (21) for execution of applications requiring use of trusted user input, a second isolated operating environment (23) adapted for secure processing of information relating to a user, and a third isolated operating environment (22) adapted for secure communication with the user input device (14). In this computing platform, no isolated operating environment can communicate with another isolated operating environment other than by a secure path (26, 27) therebetween. When an application executing in the first isolated operating environment requires provision of trusted user input, the user provides user input through the user input device (14) to the third isolated operating environment (22). The user input is then provided to the second isolated operating environment (23), and the second isolated operating environment (23) provides a service relating to the trusted user input as required by the application executing in the first operating environment (21).
    • 计算平台(20)适于可靠地使用可信用户输入。 计算平台(20)包括用户输入设备(14),用于执行需要使用可信用户输入的应用的第一隔离操作环境(21),适于安全地处理与 用户和适于与用户输入设备(14)的安全通信的第三隔离操作环境(22)。 在该计算平台中,没有隔离的操作环境可以与另一个隔离的操作环境之间的通过其间的安全路径(26,27)进行通信。 当在第一隔离操作环境中执行的应用程序需要提供可信用户输入时,用户通过用户输入设备(14)向第三隔离操作环境(22)提供用户输入。 然后将用户输入提供给第二隔离操作环境(23),并且第二隔离操作环境(23)提供与在第一操作环境(21)中执行的应用程序所需的可信用户输入相关的服务。
