During the boot process, a secure wireless display connect module of the BIOS can authenticate a wireless display and determine whether the wireless display can comply with the HDCP. When the secure wireless display connect module determines that the wireless display is HDCP compliant, the secure wireless display connect module can create an ACPI secure blob in which is stored a shared session key generated as part of determining that the wireless display is HDCP compliant. A video authentication session module of the BIOS can then retrieve this shared session key from the ACPI secure blob and use it to encrypt video frames that are to be sent to the wireless display. The video authentication session module may additionally embed a session ID and a timeout into each video frame which the wireless display can employ to detect when the video frame should no longer be displayed.
