Abstract: A processing device searches executing at least one of a boot loader or a kernel for the operating system searches for an extensible firmware interface (EFI) binary object. Responsive to finding a first EFI binary object, the processing device verifies that a first signature associated with the first EFI binary object is valid using a platform key. Responsive to verifying that the first signature for the first EFI binary object is valid, the processing device performs the following operations: identifying a first public key encapsulated in the first EFI binary object, wherein the first public key is associated with a non-EFI certificate authority; extracting the first public key from the first EFI binary object; and performing at least one of a) passing the first public key to a kernel of an operating system (OS) or b) exposing the first public key to a user space of the OS.

Abstract: A method and system for optimizing network bandwidth usage in a remote desktop system. A client generates a stream of input events that contain position information of a cursor shown on a display of the client. The client estimates characteristics of a network that couples the client to a server. Based on estimation of the characteristics, the client adjusts the number of input events batched into a packet to be sent from the client to the server over the network.

Abstract: Graphics rendering in a virtual machine system is accelerated by utilizing host graphics hardware. In one embodiment, the virtual machine system includes a server that hosts a plurality of virtual machines. The server includes one or more graphics processing units. Each graphics processing unit can be allocated to multiple virtual machines to render images. A hypervisor that runs on the server is extended to include a redirection module, which receives a rendering request from a virtual machine and redirects the rendering request to a graphics driver. The graphics driver can commands an allocated portion of a graphics processing unit to render an image on the server.
