摘　　要：量子密码通信是目前公认的唯一的绝对安全的通信方式,任何获取量子信息的操作都会因破坏量子态而被通信双方发现,从而根本上杜绝了信道窃听的存在.研究了量子直传乒乓协议的工作原理和安全特性,提出了基于P2P网络技术和量子直传乒乓协议的安全即时通信系统模型,该模型可以在保证准安全的前提下,允许通过量子信道直接传送明文.The quantum password message is the only absolutely scure communication mode generally recognized in that any operations which obtain quantum information will be discovered by both parties because of breaking quantum which, eradicates completely channel eavesdropping. The paper studies the work principle and safe characteris- tic of spreading the Ping - pong protocol. Based on the P2P network technique and quantum Ping - pong protocol and proposes the which, in the prerequisite of ensuring quasi -satety, can allows delivering plain text directly through quantum channel.
