摘要
洋葱路由技术在公网上提供双向、实时的匿名通信,其面向连接和严格的源路由方式导致效率低、扩展性差。利用分布式的概念,采用分段连接技术思想提出了一种安全、高效的分布式洋葱路由机制(DORS),给出了DORS路由实现算法,并从方案实现效率、安全性方面对DORS进行了分析。分析结果表明DORS具有良好的扩展性、鲁棒性、简单性和有效性。
Onion routing is used for anonymous communication over a public network. Its anonymous connections are bidirectional and near real-time. However, the onion routing, based on connection-oriented and strict source routing, is low in efficiency and scalability. A secure efficient distributed onion routing scheme (DORS) is described. Its implementaion is based on multisegment TCP and loose source routing. The scheme maximizes the utilization of best-effort routing entries. Analysis results show that DORS is scalable, robust, simple and efficient.'
