Abstract: A trustzone graphic rendering method in an operating system (OS) divided into a normal world (NWD) and a secure world (SWD) corresponding to a trustzone. The trustzone graphic rendering method includes generating an image resource used to generate a trustzone user interface (UI) in the NWD, transmitting the image resource from the NWD to the SWD, and generating the trustzone UI in the SWD, by separating and editing the image resource including a plurality of objects, wherein the separating and editing is performed in units of objects.
