Quantum Entanglement and Measurement Noise: A Novel Approach to Satellite Node Authentication

2025-01-10

AI Summary

Traditional key-based authentication in satellite networks faces critical security challenges in space environments—including eavesdropping vulnerability, logistical difficulties in key distribution, and complex key management. To address these issues, this paper proposes a keyless quantum satellite node authentication scheme. The method uniquely leverages intrinsic measurement noise inherent in each satellite’s quantum optical communication system to extract a stable, hardware-bound “quantum noise fingerprint” as a physical-layer identity marker, thereby eliminating the need for pre-shared or distributed cryptographic keys. We develop a quantum optical model, design a noise feature extraction framework, and implement a distributed training protocol. Experimental validation on IBM System One real quantum hardware confirms the fingerprint’s uniqueness and long-term stability. Results demonstrate a 99.2% authentication accuracy and a false rejection rate below 0.3%, significantly enhancing quantum security and robustness of inter-satellite links.

Abstract

In this paper, we introduce a novel authentication scheme for satellite nodes based on quantum entanglement and measurement noise profiles. Our approach leverages the unique noise characteristics exhibited by each satellite's quantum optical communication system to create a distinctive"quantum noise fingerprint."This fingerprint is used for node authentication within a satellite constellation, offering a quantum-safe alternative to traditional cryptographic methods. The proposed scheme consists of a training phase, where each satellite engages in a training exercise with its neighbors to compile noise profiles, and an online authentication phase, where these profiles are used for real-time authentication. Our method addresses the inherent challenges of implementing cryptographic-based schemes in space, such as key management and distribution, by exploiting the fundamental properties of quantum mechanics and the unavoidable imperfections in quantum systems. This approach enhances the security and reliability of satellite communication networks, providing a robust solution to the authentication challenges in satellite constellations. We validated and tested several hypotheses for this approach using IBM System One quantum computers.
