The AdderView Secure KVM switch allows a keyboard, monitor and mouse to be shared between high and low security systems, sometimes known as red and black networks, and is designed carefully to prevent information flowing between computers or to the outside world via emissions snooping. The AdderView Secure design prevents sensitive data from leaking between ports, sensitive data leaking to the outside world and sensitive data from being stored in the device to actively combat a range of potential leakage "threats".
Unique one-way data paths ensure that data isolation does not rely on trusting microprocessor software, but is instead assured by hardware and prevents hidden software weaknesses that could potentially cause data leakage. A uni-directional structure also protects against timing analysis or forced malfunction attacks and prevents computers influencing the operation of any common circuitry.
The AdderView Secure 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 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 cleared once they have been used.
