# [https://arxiv.org/abs/quant-ph/0105032 GC-QDS (2001)] uses [[quantum one way function]] f(); Private keys: classical input x, Public keys: quantum output f(x). '''Requires''' quantum memory, quantum one way function, authenticated quantum and classical channels, [[SWAP Test]] (universal quantum computer). [[Unconditionally Secure]]

'''Requires''' quantum memory, quantum one way function, authenticated quantum and classical channels, [[SWAP Test]] (universal quantum computer). [[Unconditionally Secure]]. [[Network Stage: Quantum Memory]]
#[https://arxiv.org/abs/quant-ph/0601130 ACJ (2006)] discusses coherent states comparison with a QDS scheme outlined in the last section. Protocol uses the same protocol as (2) but replaces qubits with [[coherent states]], thus replacing SWAP-Test with [[Coherent State Comparison]]. Additionally, it also requires quantum memory, authenticated quantum and classical channels, [[multiports]]. [[Unconditionally Secure]]

#[https://arxiv.org/abs/1309.1375 DWA (2013)] first QDS scheme without quantum memory based on [https://arxiv.org/abs/quant-ph/0601130 (3)].

#[https://journals.aps.org/pra/abstract/10.1103/PhysRevA.90.042335 AL (2014)] Establishes coherent state mapping of (2). Replaces SWAP Test with beam splitters. Uses [[Unambiguous State Discrimination (USD)]] (State Elimination). '''Requires''' [[Phase encoded Coherent states]], [[Balanced Beam Splitters]]. No explicit security proof provided. [[Network Stage: Prepare and Measure]]
#[https://arxiv.org/abs/1505.07509 AWA (2015)] security proof for generalisation of [https://arxiv.org/abs/1403.5551  WDKA (2015)] and [https://arxiv.org/abs/1309.1375 DWA (2013)] to more than two recipients case.
#[https://www.researchgate.net/publication/280062082_Practical_Quantum_Digital_Signature YFC (2016)] first QDS scheme without authenticated (trusted) quantum channels. Demonstrates one protocol with two implementation, [[two copies of single photon]] method and  [[decoy state]] method. First uses single qubit photons in three bases; Private key: classical description of states, Public key: pair of [[non-orthogonal states]] in any two of the three bases. '''Requires''' authenticated classical channels, [[polarisation measurement]] in three bases, [[Unambiguous State Discrimination (USD)]] (State Elimination), uses quantum correlations to check authentication.  Decoy State method uses [[phase-randomised weak coherent states]], [[50:50 Beam Splitter (BS)]], [[Unconditionally Secure]] [[Network Stage: Prepare and Measure]].
#[https://www.researchgate.net/publication/280034032_Secure_Quantum_Signatures_Using_Insecure_Quantum_Channels  AWKA (2015)] QDS scheme without authenticated quantum channels using parameter estimation phase. Uses a Key Generations Protocol (KGP) where noise threshold for Seller-Buyer and Seller-Verifier is better than when distilling secret key from QKD. Seller sends different key to Buyer and Verifier using KGP. This anamoly is justifiable due to symmetrisation.'''Requires''' authenticated classical channels, [[decoy state BB84 QKD]] setup. [[Unconditionally Secure]] [[Network Stage: Prepare and Measure]].
#[http://iopscience.iop.org/article/10.1088/1742-6596/766/1/012021 MH (2016)] security proof for generalisation of [https://www.researchgate.net/publication/280034032_Secure_Quantum_Signatures_Using_Insecure_Quantum_Channels  AWKA (2015)] to more than two recipients case.
#[https://www.nature.com/articles/srep09231 WCRZ (2015)] demonstrates sending multi-bit classical messages using [https://www.researchgate.net/publication/280034032_Secure_Quantum_Signatures_Using_Insecure_Quantum_Channels  AWKA (2015)] or other similar protocols.
#[https://www.sciencedirect.com/science/article/pii/S0030402617308069 SWZY (2017)] Discusses an attack and suggests corrections on existing QDS scheme using single qubit rotations. Protocol uses rotation, qubits, [[one-way hash function]]; Private keys: angle of rotation, Public keys: string of rotated quantum states. '''Requires''' [[random number generator]], [[one-way hash function]], quantum memory, key distribution.
