Libhcs is a C library implementing a number of partially homormophic encryption schemes. Refer to https://github.com/tiehuis/libhcs.
QHCS is a high-performance asynchronous offloading framework based Intel QAT for partially homomorphic encryption algorithm.
Libhcs4QHCS is the QHCS version of libhcs.
Now, libhcs4QHCS have implemented Paillier’s offloading to QAT.
cd /yourworkspace
git clone https://github.com/ColonelDan/libhcs4QHCS.git
QHCS is based QAT, first we need install QAT drive (hardware version we use is dh8970).
cd /yourworkspace/libhcs4QHCS/tar
tar -xzof QAT.tar.gz
cd QAT
chmod -R o-rwx *
apt-get update
apt-get install pciutils-dev
apt-get install g++
apt-get install pkg-config
apt-get install libssl-dev
./configure
make
make install
make samples-install
service qat_service start
export ICP_ROOT=/yourworkspace/libhcs4QHCS/tar/QAT
then, rewrite 2 item in all 3 QAT config file: /etc/c6xx_dev0.conf、/etc/c6xx_dev1.conf、/etc/c6xx_dev2.conf:
CyNumConcurrentAsymRequests = 2048
NumberCyInstances = 1
QHCS need a customed OpenSSL:
cd /yourworkspace/libhcs4QHCS/tar
tar -xzof openssl-master-g.tar.gz
cd openssl-master-g
then, you can refer to OpenSSL homepage for install it.
Dependencies for libhcs:
sudo apt-get install libgmp-dev cmake
Assuming all dependencies are on your system, the following will work on a typical linux system.
First, you need rewrite 2 macro base your dir path in CMakeLists.txt
set(ICP_ROOT "/root/QAT") #different for your machine
set(SSL_ROOT "/home/dan/openssl-master-g") #different for your machine
Then, you can install:
cd /yourworkspace/libhcs4QHCS
mkdir build
cd build
cmake ..
make hcs
sudo make install # Will install to /usr/local by default
make QHCS_bench
To uninstall all installed files, one can run the following command:
sudo xargs rm < install_manifest.txt
libhcs4QHCS gives a benchmark to test QHCS's performance.
After “make QHCS_bench”，then
cd bin
./QHCS_bench
