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...

Single-Database Private Information Retrieval with Constant Communication Rate
We present a single-database private information retrieval (PIR) scheme with communication complexity O(k+d), where k ≥ log n is a security parameter that depends on the database...

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....

Efficient Computationally Private Information Retrieval from Anonymity or Trapdoor Groups
A Private Information Retrieval (PIR) protocol allows a database user, or client, to obtain information from a data- base in a manner that prevents the database from knowing which...
