"Publius: A robust, tamper-evident, censorship-resistant web publishing system"

Aviel D. Rubin

We describe a system that we have designed and implemented for publishing content on the web. Our publishing scheme has the property that it is very difficult for any adversary to censor or modify the content. In addition, the identity of the publisher is protected once the content is posted. The system has robustness properties that make content available, even in the face of DDOS attacks.

Our system differs from others in that we provide tools for updating or deleting the published content, and users can browse the content in the normal point and click manner using a standard web browser and a client-side proxy that we provide. All of our code is freely available.
