I am looking for a good library that can perform pairing based cryptography (PBC).
One I could find is jPBC
What have others used? and their experiences?
The idea is to test the performance of algorithms using standard pairings (Weil, Tate) as well as some of the newer proposals without getting my hands too much dirty in the math.
I do work in this space as well. The best thing we could find in java was jPBC. Its not very good.
Non java alternatives:
MIRACL: I believe this is the current
fastest c implementation.
charm crypto: a python framework for
rapidly prototyping crypto systems. Full disclosure, I am a dev on
it. It has bindings to some subset of MIRACL and Lynn’s PBC lib.
These are more than enough to impliment most schemes.These subsets
are expanding and probably can be readily expanded without getting
into the math involved. Given specific requests, we might even be willing to do those
extensions
Furthermore, it already has support for benchmarking that can
give specific time spent in cryptographic operations, the number of operations (e.g.
pairings and exponentiations), and other stats.
