DragoonITCN's VEGAS DATA DIODE is a non-ruggedized module that addresses concerns regarding use of untrusted, commercial-off-the-shelf (COTS) bus logging on aircraft with a MIL-STD-1553 or ARINC-429 bus interface.
VEGAS is inserted between the active bus and a "receive only" Line Replaceable Unit (LRU) to ensure that it is only capable of receiving bus traffic. In this scenario, the aircraft's interface bus would be isolated if the LRU had been maliciously modified to transmit harmful messages on the bus. The VEGAS DATA DIODE allows the aircraft operator/integrator to purchase MIL-STD-1553 (or ARINC-429 [optional]) receive-only COTs and LRUs, and trust that the bus is isolated from intentional or unintentional cyber effects from that LRU.

* Simple Design
VEGAS is a simple, single-chip solution. * Trusted Design
There are no microcontrollers or processors in the device which could be maliciously altered. * Avionics Safety
VEGAS protects the avionics bus from malicious traffic. Additionally, it can protect the bus in case of an LRU failure or voltage transients that could couple onto the avionics bus. |
Hardware has been subjected to the following tests:
