Based on the quantum asymmetric encryption with trapdoor information, a quantum public-key signature scheme is proposed. In our scheme, the signer signs a message with his/her private key, while the verifier verifies the quantum signature with the corresponding quantum public key. The signer’s private key and public key are asymmetric, and the signing algorithm and verifying algorithm are asymmetric as well. The security of the private key depends on the unconditionally secure deterministic quantum communication protocol rather than the classical one-way function. All the algorithms in our scheme are public. Hence, our scheme obeys Kerckhoffs’s principle. Our scheme is secure against forgery, repudiation, and eavesdropping attacks. On the other hand, in our scheme, the verifier need not perform any quantum swap test. The signer’s key pair can be reused due to the secrecy property of the private key. Compared with similar schemes, ours is relatively more secure and efficient.

基于不对称量子加密和活板门信息的量子公钥签名方案

基于带有陷门信息的量子非对称加密，提出了一种量子公共密钥签名方案。在我们的方案中，签名者使用其私钥对消息签名，而验证者使用相应的量子公钥验证量子签名。签名者的私钥和公钥是不对称的，签名算法和验证算法也是不对称的。私钥的安全性取决于无条件安全的确定性量子通信协议，而不是经典的单向功能。我们方案中的所有算法都是公开的。因此，我们的方案遵循Kerckhoffs的原理。我们的方案可防止伪造，抵赖和窃听攻击。另一方面，在我们的方案中，验证者无需执行任何量子交换测试。由于私有密钥的保密性，签名者的密钥对可以重复使用。与类似方案相比，我们的方案相对更安全，更高效。
