 Following is the list of a few more protocols with similar requirement (quantum memory) but small variations.
 '''Theoretical Papers'''
-# [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/0105032 GC-QDS (2001)] above protocol
-##'''Requires''' quantum memory, quantum one way function, authenticated quantum and classical channels, [[SWAP Test]] (universal quantum computer).
-##Security: [[Information-theoretic]]
 #[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]].
