MDI-QDS is so far the best [[:Category:Prepare and Measure Network Stage|Prepare and Measure Network Stage]] QDS protocol. It does not rely on the measurement devices and is easy from implementation point of view. Unlike classical schemes, this protocol does not assume a ''trusted'' arbitrator. As the platform of widely implemented MDI-QKD is available, MDI-QDS can be implemented most efficiently and provides the best security in the QDS protocols discovered so far. Another approach would be to adapt DI-QKD for key generation. Here one would neither trust the measurement devices nor the source. As seller and buyer both act as an adversary in QDS protocols, we do not want depend on our state preparation devices either. This has not been studied yet due to as QDS protocols discovered so far yet do not match up to the efficiency of classical and post-quantum digital signature schemes in terms of signing time, key length, etc. | MDI-QDS is so far the best [[:Category:Prepare and Measure Network Stage|Prepare and Measure Network Stage]] QDS protocol.
