论文摘要
我们描述了对等电子邮件的简单方法，该方法将允许普通工作站和移动设备的用户在不依赖第三方邮件服务器运营商的情况下交换消息。至关重要的是，该系统允许参与者建立和使用多个非链接身份进行互动。该体系结构利用普通的SMTP进行消息传递和对等通信。该设计提供了一种强大的，不感知的方法，可以使用自我认证的洋葱服务名称来引导基于公共钥匙的信任网络，以用于端到端的身份验证和加密，而当发送者和收件人不同时在线时，可以用来促进消息传递。我们展示了该系统如何与现有的电子邮件系统和范式互操作，从而使用户可以持有其他人可以通过IMAP检索或作为系统参与者与外部电子邮件用户之间的继电器操作的消息。最后，我们展示了如何使用广播协议实现邮件列表以及如何使用分布式分类帐技术来引导列表成员之间共享知识的共识。
We describe a simple approach to peer-to-peer electronic mail that would allow users of ordinary workstations and mobile devices to exchange messages without relying upon third-party mail server operators. Crucially, the system allows participants to establish and use multiple unlinked identities for communication with each other. The architecture leverages ordinary SMTP for message delivery and Tor for peer-to-peer communication. The design offers a robust, unintrusive method to use self-certifying Tor onion service names to bootstrap a web of trust based on public keys for end-to-end authentication and encryption, which in turn can be used to facilitate message delivery when the sender and recipient are not online simultaneously. We show how the system can interoperate with existing email systems and paradigms, allowing users to hold messages that others can retrieve via IMAP or to operate as a relay between system participants and external email users. Finally, we show how it is possible to use a broadcast protocol to implement mailing lists and how distributed ledger technology might be used to bootstrap consensus about shared knowledge among list members.
