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.},
