SecureVoiceComms-Pro

Advanced Encrypted Voice Communication System with AES256

About SecureVoiceComms-Pro

SecureVoiceComms-Pro is an encrypted voice communication system designed for secure and reliable voice transmissions. Leveraging modern encryption techniques, it provides a robust solution for confidential and clear audio communication.

Features:

• Robust Encryption: Utilizes the AES256 cryptographic library to secure communications.
• Audio Processing: Digital signal processing for audio capture and playback.
• File-based Transmission Simulation: Simulates transmission of encrypted voice data through file input/output.
• Python-based: Developed in Python, enabling easy integration and customization.

Intended Users:

Ideal for users requiring secure communication channels in various domains, including business, remote work, and confidential discussions.

Use Case Scenarios:

Versatile for scenarios like remote meetings, secure business conversations, and any situation where encrypted voice communication is crucial.

Hardware Setup:

• Audio Output (Headphone/Speaker): Connect the headphone/speaker pin to a DAC (Digital-to-Analog Converter) on the Raspberry Pi Zero to output decrypted audio signals.
• Audio Input (Microphone): Connect the microphone pin to an ADC (Analog-to-Digital Converter) on the Raspberry Pi Zero to input audio signals.
• Push-to-Talk (PTT) Control: Connect the PTT pin to a GPIO on the Raspberry Pi Zero to control the PTT button simulation.
• Ground Connection: Ensure there is a common ground connection between the Raspberry Pi Zero and the radio.
• ADC/DAC Modules: Connect the ADC (Analog-to-Digital Converter) and DAC (Digital-to-Analog Converter) modules to the Raspberry Pi Zero via the I2C interface.

Enable I2C Interface:

Install Python 3 and PIP:

sudo apt install python3 python3-pip

Install Adafruit Libraries:

pip3 install adafruit-circuitpython-ads1x15 adafruit-circuitpython-mcp4725

Install Other Required Libraries:

pip3 install gpiozero
pip3 install numpy
pip3 install cryptography

Install SoundDevice Library:

pip3 install sounddevice
sudo apt install libportaudio2

Running Your Scripts:

Use the following command to run your main.py script:

python3 main.py

Startup Scripts:

You can use a crontab entry or create a systemd service for automatically running your scripts at startup. Using Crontab:

Edit your crontab file:

crontab -e

Add the following line to the crontab file, replacing /path/to/your/main.py with the full path to your main.py script:

@reboot python3 /path/to/your/main.py

Using Systemd Service:

Create a systemd service file:

sudo nano /etc/systemd/system/myapp.service

Add the following content to the service file, replacing /path/to/your/main.py with the full path to your main.py script:

[Unit]
Description=My App Service
After=multi-user.target

[Service]
Type=idle
ExecStart=/usr/bin/python3 /path/to/your/main.py

[Install]
WantedBy=multi-user.target

Enable the service to start on boot:

sudo systemctl enable myapp.service

Start the service:

sudo systemctl start myapp.service

Error Correction/Prevention Modules:

• Frequency Hopping Spread Spectrum (FHSS)
• Error Correction with Convolutional Redundancy and Fail-Safes
• Convolutional Codes with Viterbi Decoding
• Checksums or Cyclic Redundancy Checks (CRC)
• Automatic Repeat Request (ARQ)
• Forward Error Correction (FEC)
• Reed-Solomon Encoding
• Interleaving

To-Do:

• Configure voltage range for ADC/DAC (ADS1115 and MCP4725).
• Ensure that the time.sleep(1/fs) matches the ADC/DAC clock.

Hardware Information:

• ADC Module: ADS1115
• DAC Module: MCP4725
