Main Features

Product is designed, manufactured and delivered in security-controlled
environments. below is a summaty of the main advanced features incorporated
in product:
Advanced isolation between computers and shared peripherals
The emulations of keyboard, mouse and display EDID, prevent direct contact
between computers and shared peripherals. Product design achieves maximal
security by keeping the video path separate with keyboard and mouse switched
together, purging keyboard buffer when switching channels. All these features
contribute to strong isolation between computer interfaces, maintained even
when product is powered off.
Unidirectional data flow: USB, audio and video
Unique hardware architecture components prevent unauthorized data flow,
including:
• optical unidirectional data flow diodes in the USb data path that filtrate
and reject unqualified USb devices;
• Secure analog audio diodes that prevent audio eavesdropping with no
support for microphone or any other audio-input device;
• Video path is kept separate from all other traffic, enforcing unidirectional
native video flow. EDID emulation is done at power up and blocks all
EDID/MCCS writes. for DisplayPort video, filtration of AUX channel exists
to reject unauthorized transactions.

Isolation of power domains
Complete isolation of power domains prevents signaling attacks.
Secure administrator access & log functions
Product incorporates secure administrator access and log functions to provide
auditable trail for all product security events, including battery backup life for
anti-tampering and log functions. Non-reprogrammable firmware prevents the
ability to tamper with product logic.
Always-on, active anti-tamper system
Active anti-tampering system prevents malicious insertion of hardware implant
such as wireless key-logger inside product enclosure. Any anti-tampering
attempt causes isolation of all computers and peripheral devices rendering
product inoperable and showing clear indications of tampering event to user.
Holographic security tamper-evident labels are placed on the enclosure to
provide a clear visual indication if product has been opened or compromised.
Metal enclosure is designed to resist mechanical tampering with all
microcontrollers protected against firmware-read, modification and rewrite.
Duplicate Output Displays
The Mini Matrix allows the user to duplicate the output displays making it easy to
project various sources in secure meeting rooms
