PETAce-Solo

PETAce-Solo is a C++ library that implements or wraps primitive cryptography schemes. It is one of the many components in the framework PETAce.

PETAce-Solo implements or wraps the following primitives that involves only one party, as implied by the same "Solo".

• Hash function: SHA-256, SHA3-256, and BLAKE2b.
• Psuedo-random number generators based on: SHAKE_128, BLAKE2Xb, and AES_ECB_CTR.
• Sampling of bytes, 32-bit unsigned integers, and 64-bit unsigned integers from the uniform distribution.
• Prime field elliptic curve group arithmetics including hash-to-curve.
• Hashing tables: Cuckoo hashing and simple hashing.
• Partially homomorphic encryption: the Paillier cryptosystem.

Requirements

System	Toolchain
Linux	Clang++ (>= 5.0) or GNU G++ (>= 5.5), CMake (>= 3.15)

Required dependency	Tested version	Use
OpenSSL	1.1.1	Cryptographic primitives
GMP	6.3.0	Bignumer operations for GMP-based Paillier

Optional dependency	Tested version	Use
GoogleTest	1.12.1	For running tests

Intel Paillier Cryptosystem Library	495beaad1f6e70741f2b5cf1279cb919fd66d894	For partially homomorphic encryption

Building PETAce-Solo

We assume that all commands presented below are executed in the root directory of PETAce-Solo.

To build PETAce-Solo library (optionally with test, benchmark, and example):

cmake -S . -B build -DSOLO_BUILD_TEST=ON -DSOLO_BUILD_BENCH=ON -DSOLO_BUILD_EXAMPLE=ON
cmake --build build

Output binaries can be found in build/lib/ and build/bin/ directories.

Compile Options	Values	Default	Description
CMAKE_BUILD_TYPE	Release/Debug	Release	Debug mode decreases run-time performance.
SOLO_BUILD_SHARED_LIBS	ON/OFF	OFF	Build a shared library if set to ON.
SOLO_BUILD_BENCH	ON/OFF	ON	Build C++ benchmark if set to ON.
SOLO_BUILD_EXAMPLE	ON/OFF	ON	Build C++ example if set to ON.
SOLO_BUILD_TEST	ON/OFF	ON	Build C++ test if set to ON.
SOLO_BUILD_DEPS	ON/OFF	ON	Download and build unmet dependencies if set to ON.
SOLO_USE_IPCL	ON/OFF	OFF	BUILD IPCL-based PHE if set to ON, GMP-based PHE if set to off

Adding Partially Homomorphic Encryption

By default, the Paillier cryptosystem is a generic implementation that uses the GMP library. For power users who seek extreme performance on supported processors, we provide the option to switch to the IPCL-based implementation. To use the IPCL-based Paillier, follow instructions of Intel Paillier Cryptosystem Library and install it to ${IPCL_INSTALL_DIR}. We recommend the commit 495beaad1f6e70741f2b5cf1279cb919fd66d894 instead of v2.0.0. Build PETAce-Solo library with extra configuration:

cmake -S . -B build -DSOLO_USE_IPCL=ON -DIPCL_DIR=${IPCL_INSTALL_DIR}/lib/cmake/ipcl-2.0.0
