WebAug 11, 2024 · A doubly-efficient PIR construction in the public-client setting promises to remove the O(n) per-client state at the server. Unfortunately, the only known such construction relies on virtual blackbox (VBB) obfuscation which is … WebWe provide two constant-round constructions, one based on square root ORAM that has O(sqrt(N) log(N)) local computation and another based on secure computation of a doubly efficient PIR that achieves local computation of O(N^ϵ) for any ϵ>0 but that allows the servers to distinguish between reads and writes.
WebNov 12, 2024 · Abstract. Private Information Retrieval (PIR) allows a client to obtain data from a public database without disclosing the locations accessed. Traditionally, the stress is on preserving sublinear work for the client, while the server’s work is taken to inevitably be at least linear in the database size. Beimel, Ishai and Malkin (JoC 2004 ... Webpre-processing stage, and constructed a multi-server preprocessing PIR scheme that is doubly e cient. That is, both the client and the server perform o(N) per-query computation after an initial preprocessing computation of size (N). Achieving doubly-e cient PIR in the single server setting remained completely open until the recent
