摘　　要：针对通信双方在通信过程中身份和位置隐私的安全问题,提出一种基于双洋葱路径的双向匿名秘密通信方案。使用随机洋葱路由和混合加密方法来保证通信过程中的双向匿名性和消息保密性。发送者和接收者通过一个公告板节点作为中介建立起两条单向的洋葱路径实现双向的匿名通信。不仅发送者和接收者无法获取对方的身份和位置信息,任意第三方都无法获得发送者或者接收者的身份和位置信息。通信内容使用AES密钥加密,公告板节点、中转节点和任意的攻击者都无法获取。实验结果表明,网络中任意两个节点之间可以实现双向匿名秘密通信。平均响应时间随着节点总数的增加呈近似线性增长,不会出现系统无法响应的情况。To solve the security problem of identity and location privacy between the two parties in the communication process,a bidirectional anonymous secret communication scheme based on double onion paths was proposed,in which the random onion routing and hybrid encryption were used to ensure bidirectional anonymity and message confidentiality in the communication process.The sender and the receiver established two one-way onion paths through a bulletin board node as an intermediary to realize two-way anonymous communication.Neither the sender nor the receiver could obtain the identity and location information of the other party,and any third party could not obtain the identity and location information of the sender or receiver.During the communication process,the information exchanged between the two parties was encrypted with the AES key,which could not be obtained by the bulletin board node,the transit node and any attacker.Experimental results show that two-way anonymous secret communication can be realized between any two nodes in the network.The average response time increases approximately linearly with the total number of nodes,and there is no situation where the system becomes unresponsive.
