ADDERView® Secure Digital: Standard 

Optimize the security of USB, DVI-I and audio KVM switching with the EAL4+ certified ADDERView Secure Switch Digital Standard 

ADDERView Secure Digital


The ADDERView® Digital Standard SecureSwitch allows a keyboard, monitor and mouse to be shared between high and low security systems, “red and black networks”, with optimized security to prevent the compromise of critical data.  Product design provides support for USB, dual link DVI-I and audio KVM switching whilst protecting information, all within a high density, small form factor unit.

  • Secured Channel Switching: device can only be directly controlled, not via peripherals
  • Security of Data: unidirectional flow of data and controlled memory limits access to information
  • Tamper Proof Design: physical casing and circuitry minimize risk of unauthorized access
  • Industry Recognized: designed to meet Common Criteria; EAL4+ certified
  • USB and audio support
  • Single or Dual Link options

Product Features

  • Uni-directional data paths for keyboard and mouse: One-way data paths ensure that data isolation is assured by hardware, rather than by microprocessor software and protect against timing analysis or forced malfunction attacks
  • Designed for minimal electromagnetic emissions and isolation of electrical crosstalk: Extensive shielding of the outer casing and of internal circuitry along with  60dB crosstalk isolation ensures that less than 1/1000th of any signal is transferred to another computer. External probing and unauthorized internal access are prevented through the unit design, with as few apertures as possible
  • No shared RAM between ports: The keyboard and mouse processor is powered down and reset at each switchover to prevent shared RAM leakages. Separate memories hold the Num, Caps and Scroll states with limited accessibility and all data buffers are actively cleared once they have been used
  • Hardwired port isolation:  Data Diodes implemented within hard-wired electronic circuitry ensure unidirectional flow of critical data paths, safeguarding any compromised peripheral by preventing reading of information or transfer of data by another system. Peripherals are always powered down and re-initialized in the event of a change of channel, providing an additional of protection against hidden peripheral malware

EAL2+ Certified    

  • No critical software reliance: Minimized use of software within the unit avoids the possibility of subversive reprogramming. One-time programmable storage replaces flash memory in all security critical areas of the device
  • Restricted USB function: The USB ports only support keyboards and mice and hotkey functions are disabled.  Other devices, such as USB storage drives cannot be connected
  • No microphone connections: To prevent small levels of crosstalk noise from being “recorded”
  • Independent power supplies block power line signaling: The circuitry for each port is independently powered from the USB lead. Power line signaling is blocked as different port circuits cannot share the same power feed
  • ADDERView SecureSwitch Digital Standard checks its own operation:  Hardware and software must align before data flow is enabled. The device continuously checks its own status; operation is paused and the error light shows in the event of any unanticipated interaction
  • Maximum compatibility through true platform independence: USB keyboard or mice and dual link DVI-I monitor interfaces are used to enable true platform independence
  • High-performance digital or analogue video: Full DVI bandwidth operation of the dual link DVI interface ensures higher end applications requiring high performance video are not compromised. The DVI interface randomizes the low order video bit in order to avoid snooping

Cable Guidelines
The special cables available for connections to each system are carefully constructed with braid and foil to provide excellent screening against signal emissions that could otherwise be eavesdropped. A similarly constructed cable is also available for the monitor connection (VSCD9).  The special cables already have ferrite cores fitted to assist with signal suppression. For USB peripheral connections, we strongly recommend that (if not already fitted) you attach ferrite cores to those cables to further assist with emission suppression.
