My PhD dissertation, "On the Implementation of Pairing-Based Cryptography", talks about many of the algorithms used by the PBC library.

Since I’ll lose my office machine soon, I moved the git repository to repo.or.cz. Git doesn’t appear to be installed on any Stanford servers. In fact, Googling for "stanford git" suggests I’m the only person here using this version control system.

Mulitplicative subgroups are handled properly so that one can pick random elements and hash to G_T. Hopefully it should be more robust in general. The code is a bit messy though, and I plan to clean it up later.

Michael Cheng kindly sent me a modified version of PBC 0.4.7 which can be compiled using Microsoft Visual C++. I have made it available on the download page.

I have not tried it myself as I don’t have this particular compiler handy.

I patched a memory leak reported by Michael Cheng. I forgot to free a temporary variable when I added Lucas sequences (which speed up D and G pairings).
