BNCurve
Introduction
This pure Nim implementation of Barreto-Naehrig pairing-friendly elliptic curve.
This is a pairing cryptography library written in pure Nim. It makes use of the Barreto-Naehrig (BN) curve construction from [BCTV2015] to provide two cyclic groups G1 and G2, with an efficient bilinear pairing:
e: G1 × G2 → GT
This code is adaptation of bn library.
Security warnings
This library, like other pairing cryptography libraries implementing this construction, is not resistant to side-channel attacks.
