Creating a project for DNA as a authentication project

Primary LanguagePython

DNA Sequencing Simulation

This project provides a Python-based simulation of the DNA sequencing process. It's designed to demonstrate the basic concepts of DNA sequencing, including genome generation, fragmentation, error simulation, and sequence assembly.

Features

  • Generate a sample genome of customizable length
  • Fragment the DNA into smaller, overlapping pieces
  • Simulate sequencing errors
  • Assemble the genome from fragmented pieces
  • Calculate assembly accuracy
  • Analyze base pair frequencies
  • Save original and assembled genomes to files
  • Interactive command-line interface
  • Includes a CPU-intensive task for performance testing

Requirements

  • Python 3.6 or higher

Installation

  1. Clone this repository: 
    git clone https://github.com/yourusername/dna-sequencing-simulation.git
  2. Navigate to the project directory: 
    cd dna-sequencing-simulation

Usage

Run the simulation using Python:

python enhanced_dna_sequencing_simulation.py

Follow the on-screen prompts to progress through each stage of the simulation.

DNA Authentication System

  1. Start the server: 
    python dna_auth_server.py
  2. Connect the Arduino Pro Micro to your computer.
  3. Run the client: 
    python dna_auth_client.py

The client will read the DNA sequence from the Arduino and attempt to authenticate with the server.

Add DNA Authentication System

This pull request adds a DNA-based authentication system to our existing DNA sequencing simulation project. The new system demonstrates how DNA sequences could potentially be used for authentication purposes in a simplified manner.

New Files Added

  1. dna_auth_server.py: A server script that authenticates DNA sequences.
  2. dna_auth_client.py: A client script that reads DNA sequences from an Arduino and authenticates with the server.
  3. arduino_dna_storage.ino: An Arduino script for storing and providing DNA sequences.

Changes to Existing Files

  • README.md: Updated to include information about the new DNA authentication system.

Features Added

  • Server-client authentication system using DNA sequences
  • Integration with Arduino for DNA sequence storage
  • Demonstration of how biological data could be used in cybersecurity contexts

How to Test

  1. Upload the arduino_dna_storage.ino script to an Arduino Pro Micro.
  2. Start the server by running python dna_auth_server.py.
  3. Connect the Arduino to your computer and run python dna_auth_client.py.
  4. Verify that the authentication process completes successfully.

Notes

  • This system is a simplified demonstration and should not be used for actual security purposes.
  • The DNA sequence used for authentication is hardcoded for demonstration purposes. In a real system, this would be securely stored and possibly dynamically generated.

Please review and let me know if any changes are needed!

Output

  • The DNA sequencing simulation will generate two text files:

    • original_genome.txt: Contains the originally generated genome sequence
    • assembled_genome.txt: Contains the assembled genome sequence after fragmentation and reassembly

  • The DNA authentication system will print the authentication result to the console.
