摘　　要：为了提高量子安全直接通信协议的安全性并同时降低其成本,该文通过对协议中检测窃听过程的分析给出了一种有效的方法,并从量子安全直接通信和量子秘密共享两种角度验证了这种方法的可行性。合法通信者使用携带有秘密消息的传输粒子检测窃听,并且不会泄露任何秘密消息。分析表明,合法通信者在不用制备单独用来检测窃听的检测粒子情况下,不仅能够让协议的量子比特理论效率达到100%,而且可以确保其无条件安全。To improve the security of quantum secure direct communication protocols and reduce their cost, tnls paper presents a new means after analyzing the process of the eavesdropping detection, and offers a quantum secure direct communication scheme and a quantum secret sharing protocol to argue for it. Players employ the travel particles carrying secret messages to detect eavesdropping, and leak noting about secret messages. Investigation shows that players can make the quantum cryptography protocol not only with qubit efficiency of 100% but also secure in case of none checking particles made for eavesdropping detection only.
