摘要
首先提出基于地理多样性和基于RTT的路由节点选择算法;然后,提出一种分层的基于地理多样性的低延迟匿名通信架构,并对此架构的安全性进行分析,提出了安全性评估算法;最后给出了模拟实验与结果分析。理论分析与模拟实验结果表明,采用该机制的HLLACF架构可以在降低通信延迟的基础上,有效地防范基于AS级别的被动攻击和各种常见攻击,并且具有很好的扩展性。
First, a router selecting based algorithm on location diversity and RTT was proposed; then a hierarchical loca- tion-diversity-based low-delay anonymous communication framework was presented.The framework＇s security was analyzed and an evaluation algorithm for security was presented. In the end, a simulation experiment and result analysis was given. The theoretic analysis and simulation experiment indicate that the HLLACF based on the mechanism can prevent AS-level passive attack and other familiar attacks well while decreasing commnunicaton delay, and HLLACF also scales well.
