函数加密库libfenc项目简介Libfenc为开源项目，源码托管于/p/libfenc//p/libfenc/，使用c语言编写，使用SVN作版本管理，使用Autotools作项目源码管理，可编译运行于多种系统平台。Libfenc支持两类属性加密方案：CP-ABE, KP-ABE具体实现三种方案：FENC_SCHEME_LSWa KP-ABE scheme over non-monotonic access structure, based on Section 6.1 of the following paper.“Lewko, Sahai and Waters: Revocation Systems with Very Small Private Keys.”FENC_SCHEME_WATERSCPa CP-ABE scheme, based on the relatively recent scheme described in Appendix C of the following paper.“Waters: Ciphertext-Policy Attribute-Based Encryption: An Expressive, Effcient, and Provably Secure Realization.”FENC_SCHEME_WATERSSIMPLECPa variant of the CP-ABE scheme above. Its based on the scheme in Appendix D of that paper, but employs a random oracle for efficiencly.“Waters: Ciphertext-Policy Attribute-Based Encryption: An Expressive, Effcient, and Provably Secure Realization.”项目结构Libfenc库提供两类属性加密方案的相关函数实现Toolkit基于libfenc库实现的可用的属性加密程序工具集Benchmark测试用例程序集安装指南Libfenc库及相关套件需从源码编译，Linux环境下使用gcc编译器，Windows环境下使用MinGW编译器。编译前需安装依赖库：gmp: 高精度运算库（//）pbc: 配对加密库（/pbc//pbc/）openssl: 密码学库（//）bison: 语法解析器生成器Linux下编译安装使用包管理软件安装相关依赖库（openssl, gmp），编译安装pbc依赖库Ubuntu下，使用apt-get install如下软件包：bisonbuild-essentiallibgmp3-devlibssl-dev以下包也建议安装（修改项目源码有用）：autoconfautomakelibtool下载pbc源码，解压，进入源码目录执行./configuremakemake install进入libfenc源码目录执行./configuremakemake install默认安装目录为/usr/local下的bin, lib, include等Windows下编译安装Windows下使用MinGW + Msys编译安装mingw-get到/projects/mingw/files//projects/mingw/files/下载mingw-get-inst在线安装包安装安装gmp库打开msys执行：mingw-get install gmp源码编译pbc库到/pbc/download.html/pbc/download.html下载pbc源码，解压到临时目录，打开Msys终端，进入pbc源码目录执行：./configure LDFLAGS=-L/mingw/lib CPPFLAGS=-I/mingw/include --enable-shared --disable-staticmake make install安装后的文件中/usr/local安装配置openssl库法1（推荐）到/source//source/下载必威体育精装版源码，解压到临时目录，使用Msys执行以下命令编译openssl库shared版：./Configure mingw sharedmake make install_sw安装后的文件在/usr/local/ssl使用该方法无需修改libfenc源码配置，但编译libfenc后的程序要带上libeay32.dll动态链接库法2openssl库使用官方Windows开发版（这里下载：/products/Win32OpenSSL.html/products/Win32OpenSSL.html）安装后将
