三粒子W态作为蜜罐粒子应用于受控量子安全直接通信中，以提高窃听检测率和防止double-CNOT攻击。三粒子W态的每个粒子被随机插入到发送序列中探测窃听，每量子位的窃听探测率达到64%。随机插入的蜜罐粒子可以防止接收者在未经控制者同意获取发送者编码前GHZ态粒子1和粒子2的正确关系，即没有控制者同意接受者无法得到任何秘密信息。在安全性分析中，通过引入熵理论得出了每量子位所能包含的最大信息量，对两种蜜罐策略进行了量化比较。如果窃听者试图窃听秘密信息，用扩展的三粒子GHZ态作为诱惑粒子可以得到每量子位58%的窃听探测率，而用三粒子W态作为诱饵可以得到每量子位64%的窃听探测率。

Three-particle W state decoy is introduced in controlled quantum secure direct communication to improve the eavesdropping detection probability and prevent the double-CNOT attack. Each particle of three-particle W state decoy is inserted into sending particles to detect eavesdroppers. The decoy particles inserted randomly can prevent the receiver from obtaining the correct correlation between particle 1 and particle 2 before sender coding on them, so that he can not get any secret information without controller's permission. In the security analysis, the maximum amount of information in a qubit is obtained by introducing the entropy theory method, and two decoy strategies are compared quantitatively. If eavesdroppers intend to eavesdrop on secret information, the per qubit detection rate can reach 64% by using three-particle W state as decoy, but 58% by using extended three-particle GHZ state as decoy.
