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… More >
