Quantum Entanglement-Based Distributed Data Verification
Jincheng Zhang
Abstract
This paper proposes a novel approach to distributed data verification leveraging the unique properties of quantum entanglement. The core claim is that a highly secure distributed data verification system can be achieved without the need for shared keys, even when individual nodes are compromised. The proposed mechanism involves constructing a network of multiple quantum processors, each storing a portion of the data. Utilizing entangled states, real-time verification of relationships between data blocks is performed, and any detected alteration is immediately flagged. Quantum Key Distribution (QKD) protocols based on entangled states serve as the underlying communication foundation. This approach fundamentally differs from existing distributed data verification methods, which rely on key exchange and are therefore vulnerable to key compromise. The inherent principles of quantum mechanics provide a stronger security guarantee, theoretically offering superior resistance to attacks. This system aims to establish a robust and secure data integrity framework in scenarios demanding high levels of trust and protection against malicious manipulation.
