摘要
Based on the asymmetric quantum cryptosystem, a new public-key quantum signature scheme is proposed. In our scheme, the signer's public key is derived from her public identity information, and the corresponding private key is generated by the trusted private key generator (PKG). Both of the public key and the private key are classical bit strings, so they are easily kept. It is very convenient for the key management of the quantum signature system. The signer signs a message with her private key, and the quantum signature can be publicly verified with the signer's public key and the quantum one-way function. Both of the private key and public key can be reused. On the other hand, in the signing phase, the signer sends the message to PKG via a classical unencrypted channel, which can be used to authenticate the identity of the signer. The proposed scheme has the properties of completeness, information-theoretic security, non-repudiation and unforgeability. Its information-theoretic security is ensured by quantum indistinguishability mechanics. On the other hand, our scheme is more efficient than the similar schemes.
