The ATEN Secure KVM products implement a secure isolation design for all models to share a single set of
peripheral components. Each peripheral has its own dedicated data path. USB keyboard and mouse
peripherals are filtered and emulated. The USB authentication device connection is on a separate circuit
from the keyboard and mouse and, after filtering for qualification, has a direct connection path to the
selected computer. The TOE does not emulate the user authentication device function. DisplayPort video
from the selected computer is converted internally to HDMI, then back to DisplayPort for communication
with the connected video display and the AUX channel is monitored and converted to EDID.
