We present ConChord, a large-scale certificate distribution system built on a peer-to-peer distributed hash table. ConChord provides load-balanced storage while eliminating many of the administrative difficulties of traditional, hierarchical server architectures. ConChord is specifically designed to support SDSI, a fully-decentralized public key infrastructure that allows principals to define local names and link their namespaces to delegate trust. We discuss the particular challenges ConChord
