Abstract


This paper proposes a mobile quantum payment agreement based on the entanglement coherence of four-particle GHZ (Greenberger-Horne-Zeilinger) state. Taking the four-particle GHZ state as the quantum channel, achieving the overall process of mobile payment through the physical properties of quantum mechanics and adopting the quantum key distribution, this protocol overcomes the limitation of computational security that generally exists in the traditional mobile payment system, and possesses the unconditional security in cryptography.
