摘要
In embodiments, an apparatus to enforce secure display view for trusted transactions may include a first input interface to receive from an application, via a trusted execution environment (TEE), viewport size data and an identifier of a display associated with a secure display of a trusted transaction; and a second input interface to receive from the application, via an untrusted execution environment, an encrypted transaction bitmap associated with the trusted transaction, to be securely displayed on the display; and an enforcement engine coupled to the first input interface and the second input interface, to verify that the size and location of the transaction bitmap are within the viewport to ensure the secure display of the transaction bitmap. In embodiments, after verification of the size and location of the transaction bitmap being within the viewport, the transaction bitmap may be displayed.
