摘要
目前多数匿名通信系统只提供发送方匿名,如群组(Crowds)利用转发概率隐藏了发送者的身份,而接收者对于Crowds的成员而言完全是公开的。该文结合发送方匿名通信系统Crowds思想和组播技术,提出一个新的双向匿名通信协议,该协议将消息在多个组成员间进行随机转发,实现了发送者匿名,而当消息决定要递交时,则以组播的方式来递交给接收者,从而实现了接收者匿名。
The most anonymity communication system only provides sender anonymity presently, such as Crowds which makes use of forward probability to conceal the identity of the sender, but the identity of responder for members in Crowds is public. According to the ideas of Crowds and multicast, a novel Bidirectional Anonymity Communication Protocol（BACP） is proposed in the paper, which forwards messages randomly in members to achieve sender anonymity. When messages are decided to submit, the messages are submitted to responder by multicast so as to realize recipient anonymity.
