Description
Summary:Quantum cryptography is the fastest growing field in quantum information science. In this paper, we demonstrate the application of quantum cryptography to financial security. Using the entanglement properties of χ -state particles and the distributed quantum one-time pad algorithm, we propose a new quantum blind signature scheme combined with the scenario requirements of supply chain finance. The main idea of the scheme is that each participant obtains a key with an associated relationship by measuring χ -state particles, and the participants sign and verify the information according to the distributed quantum one-time pad algorithm and the above key obtained. We carefully proved the correctness of the scheme. Under the security analysis, we preset five common attack methods using the scenario-resistance method. We verify that our scheme can prevent them.
