摘要
洋葱路由技术是指一个在公用网络上广泛运用的基于P2P的匿名通信技术,它使得攻击者既不能进行窃听,也不能实施流量分析,实现了信息发送者和接收者的匿名性,也保护了信息内容本身的安全。针对当下洋葱路由实现的基本模型,结合群签名技术和分布式的概念,文中提出了一种基于群签名的分布式洋葱路由方案,并对其性能做了简单的分析,证明确实在路径的隐蔽性、系统的安全性等方面都有了较好的提升。
Onion Routing is a widely used technology for private communication over public network. It provides anonymous connections by using the loose source routing protocol strongly resistant to both eavesdropping and traffic analysis. What advantage it brings is that it hides contents of being-sent message, the information that who is talking to whom, and how often. According to the basic model of onion routing and integrated with the group signature technology, a distributed onion routing scheme is proposed, and the system performance remarkably enhanced.
