Digital materials can be protected from failures by replicating them at multiple autonomous, distributed sites. A significant challenge in such a distributed system is ensuring that documents are replicated and accessible despite malicious sites. Such sites may hinder the replication of documents in a variety of ways, including agreeing to store a copy but erasing it instead, refusing to serve a document, or serving an altered version of the document. We describe the design of a a Peer-to-peer Information Preservation and Exchange (PIPE) network: a distributed replication system that protects documents both from failures and from malicious nodes. We present the design of a PIPE system, discuss a threat model for malicious sites, and propose basic solutions for managing these malicious sites.
