# [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).

#[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]].

#[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. | ##Security: [[Information-theoretic]] | ||
