CP-ABE环境配置

本环境配置步骤参考互联网：

1、安装m4

sudo apt-get install m4

2、安装gmp
http://gmplib.org/  下载gmplib

./configure
make
make check
sudo make install

3、安装pbc
http://crypto.stanford.edu/pbc/download.html 下载pbc
解压，安装

./configure

出现

 flex not found

执行

sudo apt-get install flex

安装成功后继续执行

./configure

出现

bison not found

运行

sudo apt-get install bison

成功后执行

./configure
make
sudo make install

4、安装cpabe toolkit

http://hms.isi.jhu.edu/acsc/cpabe/ or http://acsc.cs.utexas.edu/cpabe/ 下载cpabe-0.11和libbswabe-0.9

安装openSSL

sudo apt-get install libssl-dev

进入libbswabe-0.9解压目录

/configure 

报错

checking for GLIB - version >= 2.0.... no
*** Could not run GLIB test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means GLIB is incorrectly installed.

执行

sudo apt-get install libglib2.-dev

安装成功后，执行

./configure
make
sudo make install

进入cpabe-0.11解压目录

./configure 

出错

/usr/bin/ld: note: '__gmpz_init' is defined in DSO /usr/local/lib/libgmp.so so try adding it to the linker command line
/usr/local/lib/libgmp.so: could not read symbols: 无效的操作

改为另一种方式编译：

sudo apt-get install checkinstall

修改Makefile，LDFLAGS后加入-lgmp

sudo checkinstall

编译成功～

执行

 cpabe-setup -h

显示信息：

Usage: cpabe-setup [OPTION ...]

Generate system parameters, a public key, and a master secret key
for use with cpabe-keygen, cpabe-enc, and cpabe-dec.

Output will be written to the files "pub_key" and "master_key"
unless the --output-public-key or --output-master-key options are
used.

Mandatory arguments to long options are mandatory for short options too.

 -h, --help                    print this message

 -v, --version                 print version information

 -p, --output-public-key FILE  write public key to FILE

 -m, --output-master-key FILE  write master secret key to FILE

 -d, --deterministic           use deterministic "random" numbers
                               (only for debugging)

安装成功～
