Code Explanation

RSA Encryption and Decryption

The RSAEncryption class handles RSA encryption and decryption using public and private keys.

Quantum Key Distribution

The QKD class simulates QKD key generation between satellites and ground stations. It generates random qubits and bases, and matches them to produce a shared key.

User Roles and Permissions

Roles (admin, user, guest) are defined with specific permissions. Users are assigned roles and MFA status.

Network Segments

Network segments (public, internal, sensitive) restrict access based on user roles. Traffic is logged if users have the appropriate permissions.

Satellite and Ground Station Communication

Satellites establish secure communication channels with ground stations using either QKD or RSA. Data is transmitted securely, and decrypted at the receiving end.

Threat Detection

The ThreatDetection class identifies unauthorized access attempts and logs them as threats.

Multi-Factor Authentication (MFA)

The MFA class simulates MFA for users. Only users with MFA enabled can authenticate successfully.

Incident Response

The IncidentResponse class responds to detected threats and logs incidents.
