Abstract: | In order to enable two parties to exchange their secret information equally, we
propose a controlled quantum dialogue protocol based on quantum walks, which
implements the equal exchange of secret information between the two parties with the
help of the controller TP. The secret information is transmitted via quantum walks, by
using this method, the previously required entangled particles do not need to be prepared
in the initial phase, and the entangled particles can be produced spontaneously via
quantum walks. Furthermore, to resist TP’s dishonest behavior, we use a hash function to
verify the correctness of the secret information. The protocol analysis shows that it is safe
and reliable facing some attacks, including intercept-measure-resend attack, entanglement
attack, dishonest controller’s attack and participant attack. And has a slightly increasing
efficiency comparing with the previous protocols. Note that the proposed protocol may be
feasible because quantum walks prove to be implemented in different physical systems
and experiments. |
