我们描述了品钦门，一个实用的假名信息检索系统。我们的设计使用一个简单的分布式信任私有信息检索协议来防止攻击者将收件人链接到他们的假名，即使在一些基础设施已经被破坏的情况下也是如此。这种方法比现有部署的假名电子邮件解决方案更好地抵抗全球流量分析，但代价是额外的带宽。我们检查模型提出的安全问题，并提出解决方案。
We describe the Pynchon Gate, a practical pseudonymous message retrieval system. Our design uses a simple distributed-trust private information retrieval protocol to prevent adversaries from linking recipients to their pseudonyms, even when some of the infrastructure has been compromised. This approach resists global traffic analysis significantly better than existing deployed pseudonymous email solutions, at the cost of additional bandwidth. We examine security concerns raised by our model, and propose solutions.
