摘　　要： 提出一种防御链路拥塞攻击的匿名通信技术,引入动态数据填充机制,将链路拥塞攻击引起的延时变化模糊化,去除统计特征,破坏匿名通信链路延时与攻击数据发送模式的关联性,达到保护通信链路安全的目标。 Circuit clogging attack is a traffic-analysis technique mainly performed on low latency anonymous systems. It could find the nodes being used to relay the anonymous streams by matching the relationship between the traffic send mode and node latency mode. We present a defense method using dynamic traffic feeding algorithm, destroy the relationship mentioned above, and protect the anonymity of the anonymous circuits.
