Abstract
A platform and a corresponding method for protecting the integrity of data transferred between the user input device and a secure processing unit. In one embodiment, this can be accomplished by establishing a virtual secure path between a device controller of the user input device and the secure processing unit. Thereafter, when sensitive information is input by the user via the user input device, the device controller is placed in a first mode of operation to securely transfer the sensitive information from the user input device to the secure processing unit over the virtual secure path. Additionally, a security indicator is placed in an Active state to indicate to the user that the sensitive information is being securely transferred to the secure processing unit.
