Program Code – Python in RFID Security and Privacy

Copy Code


# Importing required libraries
import RPi.GPIO as GPIO
import SimpleMFRC522
from cryptography.fernet import Fernet

# This function generates and returns a new encryption key
def generate_encryption_key():
    return Fernet.generate_key()

# This function encrypts the data using the encryption key
def encrypt_data(data, encryption_key):
    fernet = Fernet(encryption_key)
    return fernet.encrypt(data.encode())

# This function decrypts the data using the encryption key
def decrypt_data(encrypted_data, encryption_key):
    fernet = Fernet(encryption_key)
    return fernet.decrypt(encrypted_data).decode()

# Setting up RFID reader
reader = SimpleMFRC522.SimpleMFRC522()

try:
    # Generating a new encryption key for this session
    key = generate_encryption_key()
    
    # Prompt user for data to write to RFID tag
    text_to_write = input('Enter data to write to the RFID tag: ')
    encrypted_text = encrypt_data(text_to_write, key)
    
    print('Now place your tag to write.')
    reader.write(encrypted_text)
    print('Data written successfully.')
    
    print('Place your tag to read.')
    # Reading the data from the RFID tag
    id, encrypted_text_read = reader.read()
    decrypted_text = decrypt_data(encrypted_text_read, key)
    
    print(f'Decrypted data read from the tag: {decrypted_text}')
finally:
    # Cleaning up GPIO resources
    GPIO.cleanup()

Code Output:

The console prompts the user to enter data to write to the RFID tag.
‘Now place your tag to write.’ message is displayed.
Once the tag is detected and written, ‘Data written successfully.’ message is displayed.
‘Place your tag to read.’ message prompts the user to let the reader read the tag.
The decrypted data is displayed in the format: ‘Decrypted data read from the tag: [user input data]’.

Code Explanation:

In the given Python program, we establish a secure method to write and read data from an RFID tag using the Raspberry Pi’s GPIO interface and the SimpleMFRC522 library, which simplifies the interaction with the RFID module.

We start by importing necessary libraries: RPi.GPIO for interfacing with Raspberry Pi’s GPIO pins, SimpleMFRC522 for handling the RFID reader, and Fernet for encryption and decryption of the data.
Two functions are defined:

generate_encryption_key(): Generates a new key for data encryption.
encrypt_data(data, encryption_key): Takes the user input and the generated encryption key, and returns encrypted data.
decrypt_data(encrypted_data, encryption_key): Decrypts the encrypted data read from the RFID tag using the encryption key, making it readable once again.

We then initialize the RFID reader with SimpleMFRC522.SimpleMFRC522().
A try-except block is used to ensure that GPIO resources are properly released, regardless of whether the script completes successfully or encounters an error.
Within the try block, an encryption key is generated for the session.
The program requests data from the user to write to the RFID tag and proceeds to encrypt this data.
The user is instructed to place the RFID tag near the reader to write the encrypted data to it.
After writing, the script prompts the user to place the tag again for reading.
The encrypted data is read from the tag, decrypted, and printed to the console, showing the original data that was written to the tag initially.

Lastly, the final statement GPIO.cleanup() ensures that the resources are properly released at the end of the operation to avoid GPIO warnings on subsequent runs.

The architecture here involves secure data storage and retrieval from an RFID tag, with encryption providing privacy and security of the data. This exemplifies a simple yet effective use of cryptography in RFID applications, potentially applicable to a range of scenarios from access control to supply chain management.
