FastORE

This is a prototype implementation of the order-revealing encryption (ORE) schemes described in the following papers:

• Practical Order-Revealing Encryption with Limited Leakage (ore.h)
• Order-Revealing Encryption: New Constructions, Applications, and Lower Bounds (ore_blk.h)

This implementation is a research prototype and serves primarily as a proof of concept and benchmarking tool for our cryptographic primitives. The code has not been carefully analyzed for potential security flaws, and is not intended for use in production-level code.

Prerequisites

Make sure you have the following installed:

• GMP 5
• OpenSSL

Currently, our system requires a processor that supports the AES-NI instruction set.

Installation

git clone --recursive https://github.com/kevinlewi/fastore.git
cd fastore
make

Running Tests

To test the basic ORE scheme (described in the first paper), use the following command:

./tests/test_ore

To test the "block ORE" scheme (described in the second paper), use the following command:

./tests/test_ore_blk

Running Benchmarks

To run the benchmarks, use the commands:

./tests/time_ore
./tests/time_ore_blk

Additional Configuration

See flags.h for additional configuration changes that are possible.
