摘要:

Tor是最流行的匿名通信覆盖网络,它通过多个中继节点传递数据包,从而向服务器隐藏客户端的身份。为了同时为客户端和服务器提供匿名性,Tor引入了洋葱服务,增加了客户端与服务器之间的中继数量。由于Tor中继的带宽有限、用户数量庞大以及中继处的多层加密,洋葱服务存在端到端延迟高和数据传输速率低的问题,这降低了用户体验,使洋葱服务不适合对延迟敏感的应用。在本文中,我们提出了一种基于UDP的框架,名为DarkHorse,它利用UDP的无连接特性来改善Tor洋葱服务的端到端延迟和数据传输开销。我们的评估结果表明,DarkHorse比常规的基于TCP的Tor洋葱服务快达3.62倍,并将Tor网络开销降低了最多47%。

英文摘要:

Tor is the most popular anonymous communication overlay network which hides clients' identities from servers by passing packets through multiple relays. To provide anonymity to both clients and servers, Tor onion services were introduced by increasing the number of relays between a client and a server. Because of the limited bandwidth of Tor relays, large numbers of users, and multiple layers of encryption at relays, onion services suffer from high end-to-end latency and low data transfer rates, which degrade user experiences, making onion services unsuitable for latency-sensitive applications. In this paper, we present a UDP-based framework, called DarkHorse, that improves the end-to-end latency and the data transfer overhead of Tor onion services by exploiting the connectionless nature of UDP. Our evaluation results demonstrate that DarkHorse is up to 3.62x faster than regular TCP-based Tor onion services and reduces the Tor network overhead by up to 47%.
