On Robust Combiners for Private Information Retrieval and Other Primitives
Abstract. Let A and B denote cryptographic primitives. A (k, m)robust A-to-B combiner is a construction, which takes m implementations of primitive A as input, and yields an implem...

One-Way Trapdoor Permutations Are Sufficient for Non-trivial Single-Server Private Information Retrieval
We show that general one-way trapdoor permutations are sufficient to privately retrieve an entry from a database of size n with total communication complexity strictly less than n....

A New Sampling Protocol and Applications to Basing Cryptographic Primitives on the Hardness of NP
We investigate the question of what languages can be decided efficiently with the help of a recursive collisionfinding oracle. Such an oracle can be used to break collisionresistan...

Single Database Private Information Retrieval with Logarithmic Communication
In this paper, we study the problem of single database private information retrieval, and present schemes with only logarithmic server-side communication complexity. Previously th...
