This library implements the MNT6_753 curve generated in [BCTV14]. The name denotes that it is a Miyaji--Nakabayashi--Takano curve of embedding degree 6, defined over a 753-bit (prime) field. The main feature of this curve is that its scalar field and base field respectively equal the base field and scalar field of MNT4_753.

Curve information:

• Base field: q = 0x01C4C62D92C41110229022EEE2CDADB7F997505B8FAFED5EB7E8F96C97D87307FDB925E8A0ED8D99D124D9A15AF79DB26C5C28C859A99B3EEBCA9429212636B9DFF97634993AA4D6C381BC3F0057974EA099170FA13A4FD90776E240000001
• Scalar field: r = 0x01C4C62D92C41110229022EEE2CDADB7F997505B8FAFED5EB7E8F96C97D87307FDB925E8A0ED8D99D124D9A15AF79DB117E776F218059DB80F0DA5CB537E38685ACCE9767254A4638810719AC425F0E39D54522CDD119F5E9063DE245E8001
