Abstract
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 \(\chi \)-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 \(\chi \)-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.
