Intrusion detection-embedded chaotic encryption via hybrid modulation for data center interconnects.

Area of Science:

• Optical communication networks
• Cybersecurity
• Information theory

Background:

• Data center interconnects (DCIs) are vulnerable to unauthorized optical access.
• Current security measures may not adequately address sophisticated optical intrusion methods.
• Dynamic spectral efficiency is crucial for optimizing DCI performance.

Purpose of the Study:

• To propose a novel chaotic encryption scheme with integrated intrusion detection for DCIs.
• To enhance the security and resilience of DCIs against optical intrusion.
• To achieve dynamic spectral efficiency for improved network performance.

Main Methods:

• A hybrid modulation scheme with adjustable segmentation for dynamic spectral efficiency.
• A chaotic hybrid symbol permutation method to obscure constellation set characteristics.
• A two-stage constellation same-set ratio testing with confidence intervals for intrusion detection.

Main Results:

• Successful encryption and transmission of a 56 Gbaud signal over an 80 km link.
• Effective detection of unauthorized optical access attempts.
• Demonstration of adjustable spectral efficiency through the hybrid modulation scheme.

Conclusions:

• The proposed chaotic encryption and intrusion detection scheme significantly enhances DCI security.
• The scheme offers adjustable spectral efficiency, optimizing network resource utilization.
• This approach provides a robust solution against optical intrusion in DCIs.
