Jincheng Zhang
Abstract
This paper presents a novel protocol for distributed key generation (DKG) leveraging quantum entanglement. The core claim is to demonstrate the secure and efficient generation of a shared secret key among multiple parties using the unique properties of entangled quantum states. The protocol utilizes a specifically designed entangled state shared between the participating nodes. This shared state facilitates the synchronous generation of keys across the distributed network. The key innovation lies in the enhanced security provided by the fundamental laws of quantum mechanics, eliminating the vulnerabilities inherent in classical DKG protocols susceptible to eavesdropping attacks. Furthermore, the protocol aims to improve key generation efficiency by utilizing the inherent correlations present within the entangled state. We detail the mathematical formulation of the protocol, including the state preparation, entanglement distribution, and key extraction phases. The proposed approach offers a promising direction for secure communication in quantum networks.
