Program Code – Enhancing Network Security with Physical Layer Key Generation Project

Certainly! Given the topic ‘Enhancing Network Security with Physical Layer Key Generation Project’ and the keyword ‘The Security Network Coding System With Physical Layer Key Generation in Two-Way Relay Networks,’ I’ll craft a Python program that aims to conceptualize how nodes in a two-way relay network could generate a shared secret key leveraging the properties of their physical channel. This is highly theoretical and simplified for educational purposes.


import numpy as np
import secrets

def generate_noise():
    '''
    Simulates generation of noise in the channel which is assumed to be symmetric for both
    channels in two-way relay networks.
    '''
    return np.random.normal(0, 1)

def simulate_channel(x, noise_level=1):
    '''
    Simulates the physical layer channel by adding noise to the transmitted signal.
    '''
    noise = generate_noise() * noise_level
    return x + noise

def extract_key_from_channel(transmission, threshold=0.5):
    '''
    Extracts a bit from the transmission signal based on a threshold.
    The idea is that both parties experience the same channel characteristics and
    can agree on bits transmitted over it.
    '''
    if transmission >= threshold:
        return 1
    else:
        return 0

def generate_shared_secret_key(length=128):
    '''
    Simulates the generation of a shared secret key using the physical layer properties
    of the network. Both the transmitter and receiver generate their parts of the key
    based on the observed channel characteristics.
    '''
    shared_secret_key = ''
    for _ in range(length):
        # Generate a random bit to transmit
        original_bit = secrets.randbelow(2)
        
        # Simulate sending the bit through the channel to the relay and back
        transmitted_bit = simulate_channel(original_bit)
        received_bit = simulate_channel(transmitted_bit)
        
        # Extract the key bit from the received transmission
        key_bit = extract_key_from_channel(received_bit)
        shared_secret_key += str(key_bit)
    
    return shared_secret_key

# Main simulation
if __name__ == '__main__':
    shared_key = generate_shared_secret_key()
    print(f'Shared Secret Key: {shared_key}')

Expected Code Output:

Shared Secret Key: 0110100101111000... [128 bits long]

Note: The actual output will vary every time the program is run due to the randomness introduced by the secrets module and the simulated channel noise.

Code Explanation:

This program is a simplified model to demonstrate how nodes in a two-way relay network could potentially generate a shared secret key leveraging the physical layer of their communication channel.

  1. Noise Generation and Channel Simulation: The generate_noise function simulates random noise in the channel, a common physical layer property. The simulate_channel function mimics the effect of this noise on a transmission by adding it to the signal.

  2. Key Extraction from Channel: The extract_key_from_channel function represents how a transmitter and receiver might extract shared bits from the transmissions. This is based on agreed thresholds, exploiting the symmetrical nature of their experience of the channel’s noise and characteristics.

  3. Shared Secret Key Generation: The generate_shared_secret_key function encapsulates the whole process of generating a shared secret key. It simulates the transmission of bits through the physical layer, affected by noise, and the extraction of a shared bit influenced by this noise. By doing this process in series, a key of a predetermined length (e.g., 128 bits) is generated.

  4. Main Simulation: It runs the key generation simulation and prints out a 128-bit shared key. The key would ideally be the same on both ends of the communication in a real two-way relay network due to the shared experience of the channel characteristics, thus enhancing network security by leveraging these physical properties.

This simulation oversimplifies the complexities involved in establishing a physical layer key generation system in real-world networking environments. However, it provides a conceptual understanding of how physical channel properties could be exploited for security purposes.
