Audio Diode - with Speaker/Headphone Control

HIGHLIGHTS

High Sec Lab’s Audio Diode mitigates the risks of eavesdropping when using peripheral audio devices by forcing unidirectional audio flow.

The Threat of Using Audio Peripherals
Attackers can take control of an audio device to:

  • Listen in to classified or sensitive conversations in secure rooms.
  • Transfer data from secure to unsecured networks

The new HSL Audio Diode family of products connects between a source (a PC usually) and an audio device (speaker/ headphone). The Audio Diode prevents attackers from exploiting audio-data leakage.

Unidirectional Flow
The Audio Diode functions as a diode that forces audio signals from a PC to be unidirectional. This prevents hackers from manipulating a speaker/headphone to function as a microphone, for picking up surrounding conversations.

Low-Pass Filter
All sounds passing through the Audio Diode go through a low-pass filter that restricts the audio frequencies to the range compatible with the human ear. This prevents hackers from attacking by broadcasting high-frequency signals to an external hacking device.

Prevents hackers from taking advantage of audio-data leakage
The diode blocks listening in to surrounding conversations, by forcing unidirectional flow. It uses a low-pass filter to block high-frequency signal attacks. It has push button to switch off access while users are away.

Small size
The 85mm X 65mm X 34mm unit takes up almost no room on your desktop.

Easy to install and operate
Quickly connects to the host PC and audio device. Users only need to click on the push button to run it.

Push-Button Control

  • Has push button to activate the speaker/headphone.
  • Can be configured (for example, to set how long the speaker remains open when conducting a Skype call). If needed, can be extended by re-pressing at end of the set period, to continue the conversation.
  • Uses a bi-color (green and red) LED to show ON/OFF status. The LED also flickers before disconnection.
  • Detects a press-and-release as a single event, to prevent pressing and holding the button nonstop.
  • When pressing the speaker button, if no sound is heard for 20 seconds, it disconnects automatically.
