Abstract: Methods and systems to bind a computer device to one or more computer systems, such that only an authorized computer system may access a protected portion of the device. A processor within the computer system may provide a proxy environment to interface between the device and a trusted environment of the computer system, such as a management environment that is secure from the proxy environment. The device may be configured to authenticate the trusted environment through the proxy environment, and to verify integrity of messages exchanged with the trusted environment through the proxy environment. Authentication may include a SSL and/or TSL handshake protocol. The device may be configured to authenticate a certificate, such as an X.509 certificate, a certificate chain, and/or a hash thereof. The device may include computer memory, a printer, display, circuit board, keyboard, mouse, pointing device, and/or other physical device.

Abstract: A system and method are disclosed. In one embodiment the system includes a physical resource that is capable of generating I/O data. The system also includes multiple virtual machines to utilize the physical resource. Among the virtual machines are a resource source virtual machine that is capable of owning the physical resource. The resource source virtual machine is also capable of sending a stream of one or more I/O packets generated from the I/O data that targets a resource sink virtual machine. The resource sink virtual machine is designated as a termination endpoint of the I/O data from the physical device. Also among the virtual machines are one or more resource filter virtual machines. Each of the resource filter virtual machines is capable of filtering I/O packets of a particular type from the stream prior to the stream reaching the resource sink virtual machine.
