摘要

高效数字签名可确保数据的完整性、真实性和不可否认性。带有公共验证器的量子签名方案是其中一种方案，它公开使用验证器进行验证，并通过半信任方的帮助将带有公共验证器的量子签名转换为指定验证器，为用户设计密钥。所提出的方案提供了一种安全的量子签名，有利于解决网上竞标、电子投票和电子支付的隐私问题。此外，与其他量子签名方案相比，公钥密码系统使其更容易实施，并能安全地抵御量子攻击。

A practical convertible quantum signature scheme with public verifiability into universal quantum designated verifier signature using self-certified public keys

Efficient digital signatures ensure the integrity, authenticity and non-repudiation of the data. A quantum signature scheme with a public verifier is one of the schemes that use the verifier publicly for verification and use the conversion of the quantum signature with the public verifier into a designated verifier via the aid of a semi-trusted party for designing the keys for the users. The proposed scheme provides a secure quantum signature, which is beneficial in addressing the issues relating to the privacy of online bidding, electronic voting and electronic payment. Moreover, the public-key cryptosystem makes it easier to implement and secure against quantum attacks as compared to the other quantum signature schemes.
