[Python知识库]Intel半同态加密Python版Paillier包安装

Intel出的Python版Paillier包，Github地址：GitHub - intel/pailliercryptolib_python: Intel Paillier Cryptosystem Library is an open-source library which provides accelerated performance of a partial homomorphic encryption (HE), named Paillier cryptosystem, by utilizing Intel? IPP-Crypto technologies on Intel CPUs supporting the AVX512IFMA instructions. The library is written in modern standard C++ and provides the essential API for the Paillier cryptosystem scheme. Intel Paillier Cryptosystem Library - Python is a Python extension package intended for Python based privacy preserving machine learning solutions which utilizes the partial HE scheme for increased data and model protection.Intel Paillier Cryptosystem Library is an open-source library which provides accelerated performance of a partial homomorphic encryption (HE), named Paillier cryptosystem, by utilizing Intel?

这个包说是需要CPU指令支持AVX512IFMA ，但是实际上不支持其实也能用，首先安装依赖：

• Python版本：我选的Python3.8，因为后续安装需要依赖numpy==1.23.1，但是这个版本比较新在Python3.7里面好像没有，所以我用的Python3.8
• GCC/G++版本：实测不要用高版本，我最开始用了GCC-11，最后虽然包能装上但是在Python里import包时会报依赖项“GLIBCXX_3.4.29”找不到，也不要用低版本（GCC-7及以下）这个包的安装至少是要GCC-8.2。我用的GCC-8.4，没有问题
• 依赖库：除nasm外其他几个包直接apt安装即可：apt install libgmp-dev libmpfr-dev libmpc-dev libomp-dev?libssl-dev?libnuma-dev
  • nasm >= 2.15：这个依赖比较关键，版本必须要大于2.15，否则安装过程会提示os.inc、asmdefs.inc文件找不到，最后会报一个recipe for target ‘xxx‘ failed。所以这个包的版本一定要装对。我直接通过apt install nasm安装上的是2.13版本，实测这个2.13不能用。可以从官网下载https://nasm.us/，官网提供的rpm格式，如果是ubuntu系统，可以使用alien命令转成deb格式进行安装
  • OpenSSL >= 1.1.0
  • numa >= 2.0.12
  • gmp >= 5.0.0
  • mpfr >= 3.1.0
• 安装：python setup.py install

实测这个包相对于Python-Phe在加密和解密操作上都可以快出10倍，如果CPU指令集支持AVX512IFMA应该还可以更快。需要注意的是Intel的这个包原生是基于一维数组做加解密的，如果要扩展到多维可能需要自己进行一些调整。
