Abstract

This paper proposes a novel distributed key agreement protocol leveraging the unique properties of quantum entanglement. The core concept involves two parties sharing a pre-established entangled state, performing correlated measurements, and directly using the measurement outcomes to generate a shared secret key. This eliminates the need for classical communication channels, significantly enhancing security by mitigating the risk of eavesdropping during key transmission and reducing latency associated with classical message exchange. The protocol addresses key challenges in entanglement-based systems, namely maintaining entanglement fidelity and ensuring synchronized measurement processing. We outline the theoretical framework, detailing the mathematical formulation of the key generation process and highlighting the critical aspects of entanglement distribution and measurement protocols. This approach represents a fundamental shift in distributed key agreement, moving towards inherently secure and efficient quantum communication systems.

Based on Quantum Entanglement Key Agreement Protocol

Jincheng Zhang

This paper presents a novel key agreement protocol leveraging the principles of quantum entanglement. The protocol, termed the "Quantum Entanglement Key Agreement Protocol" (QEKAP), aims to establish a shared secret key between two parties, Alice and Bob, without relying on classical communication channels for key exchange. The core of the protocol utilizes entangled photon pairs to generate correlated random keys, followed by the application of quantum error correction codes to mitigate the effects of noise and ensure accurate key transmission. We demonstrate the feasibility of this approach and highlight its potential advantages over traditional key exchange methods, specifically addressing vulnerabilities associated with eavesdropping and man-in-the-middle attacks. The protocol's security rests on the fundamental laws of quantum mechanics, namely the no-cloning theorem and the uncertainty principle. The key parameters influencing the protocol's performance, such as entanglement fidelity and the overhead introduced by the quantum error correction scheme, are analyzed. Simulation results indicate that QEKAP provides a robust and secure solution for key distribution in quantum networks.
