CompresssLWE

CompressLWE is an open-source library, built on top of pailliercryptolib, that allows for compression of LWE ciphertexts in transit from server to client in an efficient way

Building the Library

Prerequisites

For best performance, especially due to the multi-buffer modular exponentiation function, the library is to be used on AVX512IFMA enabled systems, as listed below in Intel CPU codenames:

• Intel Cannon Lake
• Intel Ice Lake
• Intel Sapphire Rapids

The library can be built and used without AVX512IFMA and/or QAT, if the features are not supported. But for better performance, it is recommended to use the library on Intel Xeon® scalable processors - Ice Lake-SP or Sapphire Rapids-SP Xeon CPUs while fully utilizing the features.

The following operating systems have been tested and deemed to be fully functional.

• Ubuntu 18.04 and higher
• Red Hat Enterprise Linux 8.1 and higher
• CentOS Stream

We will keep working on adding more supported operating systems.

Dependencies

Must have dependencies include:

cmake >= 3.15.1
git
pthread
Intel C++ Compiler Classic 2021.3 for Linux* OS
Intel oneAPI DPC++/C++ Compiler for Linux* OS >= 2021.3
g++ >= 8.0
clang >= 10.0

The following libraries and tools are also required,

nasm >= 2.15
OpenSSL >= 1.1.0

OpenSSL can be installed with:

# Ubuntu
sudo apt install libssl-dev
# Fedora (RHEL 8, Centos)
sudo dnf install openssl-devel

In order to install nasm, please refer to the Netwide Assembler webpage for download and installation details.

Instructions

for building IPCL, clone their repo, then:

cmake -S . -B build -DCMAKE_INSTALL_PREFIX=/path/to/install/ -DCMAKE_BUILD_TYPE=Release -DIPCL_TEST=OFF -DIPCL_BENCHMARK=OFF
cmake --build build -j
cmake --build build --target install

For building compressLWE:

mkdir build
cd build
cmake .. -DCMAKE_INSTALL_PREFIX=[PATH TO IPCL]
make
