ark-ec 0.2.0 - Docs.rs

ark-ec

This crate defines Elliptic Curve traits, curve models that follow these traits, and multi-scalar multiplications. Implementations of particular curves using these curve models can be found in arkworks-rs/curves.

The available elliptic curve traits are

AffineCurve - Interface for elliptic curve points in the 'canonical form' for serialization.
ProjectiveCurve - Interface for elliptic curve points in a representation that is more efficient for most computation.
PairingEngine - Pairing friendly elliptic curves (Contains the pairing function, and acts as a wrapper type on G1, G2, GT, and the relevant fields).
CycleEngine - Wrapper type for a cycle of pairing friendly elliptic curves.

The elliptic curve models implemented are

Short Weierstrass curves. The AffineCurve in this case is in typical Short Weierstrass point representation, and the ProjectiveCurve is using points in Jacobian Coordinates.
Twisted Edwards curves. The AffineCurve in this case is in standard Twisted Edwards curve representation, whereas the ProjectiveCurve uses points in Extended Twisted Edwards Coordinates.
