Ethernet Passive Mutual Authentication Scheme on Quantum Networks

Area of Science:

• Computer Science
• Network Security
• Cryptography

Background:

• Growing demand for secure and efficient communication networks necessitates robust authentication in EPONs.
• Traditional authentication methods face challenges in advanced network environments.
• The integration of Software-Defined Networking (SDN) offers new possibilities for network management and security.

Purpose of the Study:

• To propose a novel, secure, and efficient mutual authentication scheme for EPONs.
• To leverage ideal lattice-based cryptography for enhanced security against sophisticated attacks.
• To explore the convergence of quantum network protocols with EPONs for future-proof security.

Main Methods:

• Developed a public-key cryptosystem based on the Ring Learning With Errors (RLWE) problem.
• Implemented mutual authentication involving Optical Network Units (ONUs), Optical Line Terminals (OLTs), and an SDN controller.
• Utilized approximate smooth projection hash functions for secure key exchange and verification.

Main Results:

• The proposed scheme provides robust security against man-in-the-middle, impersonation, replay, and known key secrecy attacks.
• Simulations show minimal delay and high registration success rates compared to traditional methods.
• Demonstrated the potential of integrating quantum network protocols for enhanced security and man-in-the-middle attack prevention.

Conclusions:

• The lattice-based mutual authentication scheme offers a secure and efficient solution for EPONs.
• The integration with quantum technologies presents a promising direction for future communication security and quantum-resistant protocols.
• The proposed approach addresses current security needs while anticipating future quantum threats.
