blindstore Goto Github PK

Blindstore is a private information retrieval data store. It provides an online lookup service which returns the correct answer without ever knowing what the question was.

Currently this repo is a stub.

• For the core cryptography implementation, see libshe.
• For a working proof of concept of the Blindstore concept, please see the blindstore-old-scarab repository. The implementation there is based on another encryption scheme.

This repo will contain an implementation of Blindstore in C++ based on the V-DGHV scheme of somewhat homomorphic encryption (libshe) presented in [1].

The library presented here is beta software and should not be used for any mission critical applications. No warranty expressed or implied is given.
