Abstract
The present invention presents apparatuses and systems for operating multiple computers from a single console using a secured KVM device, while preventing information leakage between the computers. The system comprises several hosts connected through a secured KVM device to keyboard and mouse and one or more user displays. Secured KVM enables standard bi-directional communication between Secured KVM and user keyboard and mouse and between hosts peripheral ports and Secured KVM. Secured KVM physically enforces unidirectional data flow from attached keyboard and mouse to attached hosts peripheral ports to avoid potential leakages between hosts.

69. An Isolated KVM combiner for multi-network computer system comprising:
-
a keyboard input configured to connect to a keyboard; a pointing device input configured to connect to a pointing device such as a mouse; a host controller receiving signals from at least one of said keyboard and pointing device; at least a first and a second peripheral interfaces, configured to connect to at least a first and second host computers respectively, wherein said at least two host computers are connected to at least two separate networks respectively; a peripheral switch, selectively directing signals from said host controller to only to the selected one of said at least first and second peripheral interfaces at a time; and at least a first and a second physical unidirectional enforcing circuitries connected between said peripheral switch and said at least a first and second peripheral interfaces respectively, enforcing data flow only from said peripheral switch to said peripheral interfaces. - View Dependent Claims (70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83)

92. A method for combining KVM function in an Isolated multi-network computer system comprising:
-
connecting peripheral ports of at least a first and a second host computers to at least a first and second peripheral emulator circuitries respectively; receiving signals from a user keyboard and a user pointing device; selecting one of said at least a first and second peripheral emulator circuitries to receive said signals from said user keyboard and a user pointing device; and physically forcing unidirectional signal flow from said at least a first and second peripheral emulator circuitries to said peripheral port of at least a first and a second host computers. - View Dependent Claims (93)
