从信息论和密码学的角度分析了两个量子对话协议和一个双向量子安全直接通信（QSDC）协议的安全性，指出这两个协议都存在部分信息泄露的问题。也就是说，任何窃听者都可以从法律的用户的公开声明中获取一些关于秘密的信息。这种现象在量子保密通信中是被严格禁止的。事实上，这一问题在最近的许多提案中都存在，因此，在后续的相关研究中值得更多的关注。
From the perspective of information theory and cryptography, the security of two quantum dialogue protocols and a bidirectional quantum secure direct communication (QSDC) protocol was analyzed, and it was pointed out that the transmitted information would be partly leaked out in them. That is, any eavesdropper can elicit some information about the secrets from the public annunciations of the legal users. This phenomenon should have been strictly forbidden in a quantum secure communication. In fact, this problem exists in quite a few recent proposals and, therefore, it deserves more research attention in the following related study.
