Analysis of one semi-quantum-honest key agreement scheme in MSTSA structure without entanglement
Abstract
We show that the key agreement scheme [Quantum Inf. Process., 20:188, 2021] is flawed. (1) It requires that the quantum channel must be intact so as to keep the transferred photon sequences complete and undamaged, even if the channel is tapped. But this is unrealistic because of quantum non-cloning theorem. (2) The user's capability is artificially assumed, who can measure a hybrid photon sequence only with $Z$-basis, unable to measure with $X$-basis. (3) It requires an authenticated classical channel for the negotiation between Alice and Server$_B$. If such a channel is available, the scheme can be greatly simplified using the mechanism in BB84 protocol.
