The ADDERView Analogue Standard SecureSwitch (AVSV1004) allows a keyboard, monitor and mouse to be shared between high and low security systems, "red and black networks". The high density, highly robust, small form factor unit ensures maximized security to prevent the compromise of critical data.
Adder AVSV1004 Features
Tempest, EAL2+ & EAL4+ (NIAP 3.0) certified
Tempest testing is a strict NSA specification and a NATO certification to ensure that sensitive equipment doesn't leak information. Adder's new secure switch has been tested and qualified to the strictest Tempest standards (USA NSTISSAM Level I and NATO SDIP-27 Level A). This and 80dB crosstalk isolation means that the switches are amongst the lowest leakage KVMs in the world.
AdderView Analogue Standard Secure switch checks its own operation
The hardware and software must agree before data flow is enabled. The switch constantly checks its own operation and will stop operating and flash its error light if an unanticipated event occurs.
Minimal emissions profile - 80dB crosstalk isolation
The AdderView Analogue Standard Secure switch is heavily shielded with double shielding in critical areas to minimize the risk of eavesdropping equipment being able to pick up signals from the equipment. The switch boasts an amazingly high level of electrical crosstalk isolation that is greater than 80dB, giving further peace of mind.
No shared RAM between ports
The keyboard and mouse processor is powered down and reset at each switchover to thwart shared RAM leakages. Separate memories hold the num, caps and scroll states and are only accessible when the relevant channel is selected. All data buffers are actively cleared once they have been used.
Secure USB function
The USB ports will only support keyboards, mice and SmartCard / Common Access Cards (CAC). Other devices, such as USB storage drives, are actively prohibited.
Independent power supplies block power line signalling
The circuitry for each port is independently powered from the USB lead. Power line signaling is therefore blocked because different port circuits don't share the same power feed.
Uni-directional data paths for keyboard and mouse
One-way data paths ensure that data isolation does not rely on trusting microprocessor software, but is instead assured by hardware and prevents a hidden software weaknesses that could potentially cause data leakage. A unidirectional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.
One time programmable microprocessors
Data isolation is assured by hardware and so is not compromised by any changes to the microprocessor software. Microprocessors use one time programmable memory so flash upgrades are not possible
