Security in 3D Graphics Drivers

Abstract

User mode driver is software component which is a medium of communication be- tween operating system and a device. Driver plays major in role what we see on display. For rendering 3d graphics on screen it needs to render through specific UMD. Optimization of debug methods and debug tools will help to reduce the time that we are currently spending over the debugs and the optimization of graphics driver code will help to reduce the number of bugs arriving in graphics driver. Incorporation of such functionality into Direct3D UMD (User Mode Driver) Driver not only improves perfor- mance, but also saves a lot of time required to debug the driver for a specific cause. It allows us to find root cause by providing the option to dump commands category wise. Hence improves debug throughput time require to debug the driver and avoid the need to debug the whole driver for any issue and also improves the performance. For running driver securely through hardware to display final render on screen, needs two kind of security 1) code security 2) hardware security 3) automation corruption. Providing hardware security is part of kernel mode driver (KMD) and automation is kind of work which can improve throughput and prevent easy access for security threats.
