摘      要：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 *** 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 ***,to resist TP’s dishonest behavior,we use a hash function to verify the correctness of the secret *** 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 *** has a slightly increasing efficiency comparing with the previous *** that the proposed protocol may be feasible because quantum walks prove to be implemented in different physical systems and experiments.
