Encryption Test Project

Overview

This project is an implementation of both analog and digital encryption methods for secure data transmission. The system simulates real-world scenarios by incorporating potential transfer drops and varying transmission rates. It includes encoding, decoding, encryption, decryption, and testing mechanisms, and successfully demonstrates the feasibility of using both analog and digital encryption techniques.

The project fulfills the initial objectives, showcasing robust functionality and a complete implementation.

Components

1. Analog Encryption & Decryption

Located in the encrypting directory, this module implements Frequency Modulation Encryption (FME) and its corresponding decryption. Files include:

• analog_encrypt.py: Handles the encryption process for analog signals.
• analog_decrypt.py: Processes analog signal decryption.

2. Digital Encryption & Decryption

• digital_encrypt.py: Encrypts data using AES.
• digital_decrypt.py: Decrypts AES-encrypted data.

3. Testing

• automated_testing.py: Provides a framework for testing all encryption and decryption functions.
• tester.py: Handles manual and specific test cases.

4. Networking

Contains modules for simulating data transmission over a network:

• server.py, sender.py, receiver.py: Simulate the roles of server and clients in data transmission.
• wire.py: Manages communication protocols.
• logging.py: Tracks transmission status.
