Abstract
Techniques are disclosed to provide security for graphical user interface elements being displayed in a system having a host operating system and a high assurance operating system. Graphical user interface elements associated with the high-assurance operating system may be prevented from being obscured and from any partial transparency. Additionally, a piece of secret information may be stored and displayed by graphical user interface elements associated with the high-assurance operating system. Coordinating certain elements of the graphical user interface elements associated with the high assurance operating system also helps to identify legitimate elements associated with the high assurance operating system. Public title information may be furnished to a host operating system windowing system to identify a window owned by a process running on a high-assurance operating system. Private title information associated with the same window may be used in the high assurance operating system.
