| 摘 要: 针对当前区块链系统存在的用户身份非法访问、身份伪造等影响区块链系统安全的问题，基于量子密钥安全性和可靠性高的特性，提出并设计了一种利用量子密码技术实现区块链系统身份认证的方案，方案中用户每次登录区块链系统时可通过比对客户端量子密钥散列值和量子密钥云服务器散列值的一致性完成身份认证，从而确保了区块链系统每次交易用户身份的合法性和安全性。实验结果表明，利用量子密码技术能够实现区块链系统用户身份安全认证，为区块链身份安全认证提供了一种新的思路。 |

| Abstract: Illegal user identity access and identity counterfeiting affect the security of the current blockchain system. Based on the high security and reliability of the quantum key, this paper proposes to design a solution to realize the authentication of the blockchain system by using quantum cryptography technology. In the solution, users can complete authentication by comparing the consistency between the hash value of client quantum key and the hash value of quantum key cloud server each time they log in to the blockchain system, thus ensuring the legitimacy and security of user identity in each transaction of the blockchain system. The experimental results show that quantum cryptography technology can realize the user authentication of the blockchain system, which provides a new idea for blockchain security authentication. |
