Dependencies

Requires:

• GNU Multiprecision Arithmetic Library (GMP) available from gmplib.org
• Victor Shoup's NTL: A Library for doing Number Theory available from shoup.net/ntl
• C++ library for Finite Fields and Elliptic Curves available from github.com/scipr-lab/libff

Build Instructions in Ubuntu

0 - Install necessary packages (see NTL's website for installation instructions)

$ sudo apt-get install build-essential git libboost-all-dev cmake libgmp3-dev libssl-dev libprocps3-dev pkg-config

1 - Initialize libff submodule:

$ git submodule init

2 - Update libff submodule:

$ git submodule update

3 - Build libff library

$ cd libff

$ git submodule init

$ git submodule update

$ mkdir build && cd build && cmake ..

$ make

4 - Build from source

$ cd ../../src/test

$ make

5 - Run the test applications

$ ./test_ssfe_ggm

$ ./test_ssfe_sm
