Abstract
A system and method is provided to permit a first computer to interact with computers in different security domains without forming covert channels. Separate GPUs are provided for each computer. An image routing map (IRM) determines which security domain is the subject of an I/O event to determine to which security domain to send the I/O event. A response is transmitted to the associated GPU and multiplexor and another response used to update the IRM, which is then provided to the MUX. The MUX uses the updated IRM to adjust the content on the monitor. Content from the security domains are able to be displayed on the monitor and in a similar manner as by the computer in each security domain.
