摘要： 基于下一跳重路由方式的Crowds匿名通信系统存在较多缺点。提出基于IPv6协议的Crowds系统，解决发送者与最后一跳的秘密共享问题。理论分析和实验结果表明，该系统的抗攻击能力与源路由方式相等，实现了接收者匿名，减少了通信延迟。

Abstract: Crowds anonymous communication system based on next hop rerouting mode has a lot of the drawback. This paper proposes a Crowds system based on IPv6 protocol, which solves the problem of secret sharing between sender and the last hop. Theoretical analysis and experimental results demonstrate that this system has the same ability of attack againsting as source rerouting mode, achieves receiver anonymity and reduces the communication delay.

Key words: anonymous communication, IPv6 protocol, receiver anonymity
