Abstract
This paper proposes a novel distributed key generation (DKG) protocol leveraging the principles of quantum entanglement. Traditional DKG protocols often rely on classical cryptographic techniques, introducing vulnerabilities to sophisticated attacks. Our protocol utilizes entangled photon pairs to establish a shared secret key between multiple parties without any prior secret sharing. The core mechanism involves the creation of an entangled state and subsequent measurements performed by the participants. The correlations inherent in quantum entanglement allow for the derivation of a shared key, guaranteeing security against eavesdropping attempts. We formally define the protocol, outlining the key parameters and security assumptions. The presented system offers a potentially more secure alternative to existing DKG methods, particularly against adversaries with access to classical communication channels. We explore the protocol's mathematical foundations, detailing the process of key generation and emphasizing the inherent security provided by the laws of quantum mechanics. This work provides a theoretical framework for a future, practical implementation of a quantum-secured DKG system.
