TLDR
The general principle for a quantum-signature scheme is proposed and investigated and can guarantee the unconditional security of the algorithm, mostly due to the correlation of the GHZ triplet states and the use of quantum one-time pads.Abstract:
The general principle for a quantum-signature scheme is proposed and investigated based on ideas from classical signature schemes and quantum cryptography. The suggested algorithm is implemented by a symmetrical quantum key cryptosystem and Greenberger-Horne-Zeilinger (GHZ) triplet states and relies on the availability of an arbitrator. We can guarantee the unconditional security of the algorithm, mostly due to the correlation of the GHZ triplet states and the use of quantum one-time pads.read more

Threshold proxy quantum signature scheme with threshold shared verification
TL;DR: A threshold proxy quantum signature scheme with threshold shared verification is proposed, where an original signer could authorize a group as its proxy signers and only t or more of n persons in the proxy group can generate the proxy signature on behalf of the original signers.

A multiparty quantum proxy group signature scheme for the entangled-state message with quantum Fourier transform
TL;DR: The analysis shows that the scheme is more efficient than other traditional quantum signature schemes, and a secure quantum proxy group signature can be achieved effectively for a contract that needs the cosigner of multi participants.

Arbitrary Quantum Signature Based on Local Indistinguishability of Orthogonal Product States
TL;DR: A new QDS scheme based on local indistinguishability of orthogonal product states is proposed, which is secure and efficient and cooperates with the arbitrator to verify the valid of the signature.

On “Arbitrated quantum signature of classical messages against collective amplitude damping noise”
TL;DR: An arbitrated signature protocol of classical messages over a collective amplitude damping channel is given and it is proved that it is secure over such a noisy quantum channel even if the arbitrator is compromised.
