Controlled quantum dialogue based on W state
We present a controlled quantum dialogue scheme by using W states. The legitimate users Alice and Bob can simultaneously exchange their secret messages with the help of the controller,Charlie. We analyze the security of the scheme and show that the scheme can efficiently resist the intercept-and-resent attack,the entangle-measure attack,and the disturbance attack.
