摘　　要：针对目前已提出的量子匿名通信协议都只建立在参与者是非自适应的基础上,而实际操作过程中参与者的自适应性是不可忽略的因素,合并信息传输和信道检测这2个过程到同一次编码中,对多方安全计算的匿名通信模型进行优化。方案使用N+1对量子连续变量EPR态,采用移动式量子态传输,将N bit经典消息编码在不同的模式中,消息接收者通过计算得到匿名消息并检验当次通信中参与者的诚实度,使得通信方案的效率提高。研究结果表明:除了指数小的概率外,发送者和接收者的匿名性和消息的私密性都得到保护。Quantum anonymous communication schemes were proposed on the condition that the participants are non-adaptive, but adaptability of participants can not be ignored in the actual operation, and so the multiple secure computing model for anonymous communication was optimized which incorporated message transmission and channel detection together in the process of encoding. N ＋1 EPR states＇ s continuous variable quantum encoded in different modes travelled among the participants, and receiver of the message could get the results by calculating and the results could be verified when the participant was dishonesty. The results show that efficiency of the scheme is effective. Furthermore, the anonymity of sender and receiver and privacy of messages are protected except with exponentially small probability.
