LIBPBC This is tested against libpbc version 0.4.18 . (The v0.8+ builds will pull the right version of libpbc and try to build it on some platforms.) COPYRIGHT Copyright (C) 2008 by Paul Miller SYNOPSIS use Crypt::PBC; my $pairing = new Crypt::PBC("params_d.txt"); my $G1 = $pairing->init_G1->random; my $G2 = $pairing->init_G2->random->double->square; my $GT = $pairing->init_GT->pairing_apply( $G1, $G2 ); ----------------------------- "Chapter 1. Overview" The following text is the Overview chapter from the PBC library documentation: The PBC library is a free portable C library designed to make it easy to implement pairing-based cryptosystems. It provides an abstract interface to a cyclic group with a bilinear pairing, and the programmer does not need to worry about, or even know about elliptic curves. It is built on top of GMP, another C library which performs arbitrary precision arithmetic on integers, rationals and floats with strong emphasis on portability and speed.
