我们提出了一个基于W态的控制量子对话方案.两个合法的用户Alice和Bob在控制者Charlie的帮助下可以同时交换他们的秘密信息.我们分析了这个方案的安全性,而且指出这个方案可以有效地抵制截取再发送攻击,纠缠测量攻击和干扰攻击.
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.
