    Centralizing Offline Phases for Private Information Retrieval Protocols

    Bachelor Thesis, Master Thesis

    Private Information Retrieval (PIR) allows a client to privately access an entry in a public database held by a server without leaking information about the client’s query. Example applications for PIR are private messaging apps and privacy-friendly lookups in medical or patent databases. Modern multi-server PIR schemes outperform single server PIR in online runtime by reducing the amount of data each server has to touch during a request, but require that a subset of the servers are non-colluding. While great effort has been put into optimizing the online runtime, the storage requirements are expensive. A promising approach to reduce the storage for a single server is a centralized, powerful computer cluster that is optimized for offline runtime and distributes the necessary data among the servers. go
