Description

A library encapsulating bilinear pairing computation and group computation in the cyclic groups G_1, G_2, G_T.

The bilinear pairing is a bilinear, non-degenerate map between G_1 and G_2 to an element in G_T.

The users can build complex pairing-based software by the Pairing library without much
knowledge of elliptic curves or pairing or number theory.

The library is smaller than 57 Kbytes, suitable for hand held devices. The size is only 3.7% of the size of the BPC library.

Maximum supported group size is 911 bits.

It is easy to compile the library for Android, ARM or x86 CPU.

The API of the library is compatible with the PBC library. It is easy for the PBC library users to port their programs to this library, only with little modification.
