A New Quantum Blind Signature Scheme with BB84-State
Entropy, 2019 The blind signature is widely used in cryptography applications because it can prevent the signer from gaining the original message. Owing to the unconditional security, the quantum blind signature is more advantageous than the classical one.

Measurement-Device Independency Analysis of Continuous-Variable Quantum Digital Signature
Entropy, 2018 With the practical implementation of continuous-variable quantum cryptographic protocols, security problems resulting from measurement-device loopholes are being given increasing attention. At present, research on measurement-device independency analysis

Applied Sciences, 2020 The quantum proxy signature is one of the most significant formalisms in quantum signatures. We put forward a quantum proxy signature scheme using quantum walk-based teleportation and quantum one-time pad CNOT (QOTP-CNOT) operation, which includes four ...

Quantum Digital Signature Using Entangled States for Network
EntropyWe propose an entanglement-based quantum digital signature (QDS) protocol optimized for quantum networks. The protocol follows the Lamport-inspired QDS paradigm but eliminates QKD post-processing by signing and verifying with raw conclusive keys, thereby

A Verifiable Arbitrated Quantum Signature Scheme Based on Controlled Quantum Teleportation. [PDF]
Entropy (Basel), 2022 In this paper, we present a verifiable arbitrated quantum signature scheme based on controlled quantum teleportation. The five-qubit entangled state functions as a quantum channel.

Unconditionally Secure Quantum Signatures [PDF]
Entropy, 2015 Signature schemes, proposed in 1976 by Diffie and Hellman, have become ubiquitous across modern communications. They allow for the exchange of messages from one sender to multiple recipients, with the guarantees that messages cannot be forged or tampered with and that messages also can be forwarded from one recipient to another without compromising ...

Cryptanalysis of a Semi-Quantum Bi-Signature Scheme Based on W States
Entropy, 2022 Recently, Zhao et al. proposed a semi-quantum bi-signature (SQBS) scheme based on W states with two quantum signers and just one classical verifier. In this study, we highlight three security issues with Zhao et al.’s SQBS scheme.

Quantum Digital Signatures without Quantum Memory [PDF]
Physical Review Letters, 2014 Quantum Digital Signatures (QDS) allow for the exchange of messages from one sender to multiple recipients, with the guarantee that messages cannot be forged or tampered with. Additionally, messages cannot be repudiated -- if one recipient accepts a message, she is guaranteed that others will accept the same message as well.
