Abstract

Zero-Knowledge Quantum Key Distribution (ZK-QKD) represents a paradigm shift in secure communication, leveraging quantum mechanics to establish key exchange without revealing the secret key itself. This paper explores the development of a novel ZK-QKD protocol, "Adaptive Complexity ZK-QKD," that dynamically adjusts key complexity based on the level of trust and security required. Current ZK-QKD systems often rely on fixed key lengths, introducing vulnerabilities with evolving security threats. Our approach utilizes quantum error correction and probabilistic optimization to tailor key complexity in real-time, reducing computational overhead while maintaining high-level security. This research addresses a critical challenge in ZK-QKD: the need for a truly adaptive and efficient protocol. The proposed method offers a substantial improvement over static approaches, enhancing security and potentially enabling broader deployment of this groundbreaking technology.
