Hi to all, I wish to implement an asymmetric bilinear mapping using a non supersingular curve defined over binary finite field. The two subgroups over the same curve are GF(2) that stands as base field and GF(2^m) that stands as extension field. I have read about pseudorandom and Koblitz curves in NIST document, but wonder whether they can be implemented with the actual pairing types within the PBC library.

I plan to perform operations on a polynomial basis or normal basis depending on what seems easier to deal with. It seems I have to generate my own curve parameters and that default pairing types provided in PBC library (especially D, F pairing types) cannot help much. Any help will be appreciated. Thanks.
