G₂ projective point representation.

Implementations

impl G2Projective

pub fn identity() -> G2Projective

Point at infinity.

pub fn generator() -> G2Projective

Fixed generator.

pub fn random(rng: impl RngCore) -> Self

Random non-identity element.

pub fn msm_vartime(points: &[G2Affine], scalars: &[Scalar]) -> Result<Self>

Multi-scalar multiplication using a variable-time Pippenger’s algorithm.

This method is faster for non-sensitive operations where timing side-channels are not a concern, as it contains input-dependent branches.

Panics

Panics if points.len() != scalars.len().

pub fn msm(points: &[G2Affine], scalars: &[Scalar]) -> Result<Self>

Multi-scalar multiplication using a constant-time Pippenger’s algorithm.

This method is suitable for cryptographic operations where resistance to timing side-channels is required.

Panics

Panics if points.len() != scalars.len().

pub fn double(&self) -> G2Projective

Point doubling.

pub fn add(&self, rhs: &G2Projective) -> G2Projective

Point addition.

pub fn add_mixed(&self, rhs: &G2Affine) -> G2Projective

Mixed addition with affine point.

pub fn clear_cofactor(&self) -> G2Projective

Clear cofactor.

pub fn batch_normalize(p: &[Self], q: &mut [G2Affine])

Batch conversion to affine.

pub fn is_identity(&self) -> Choice

Check if point at infinity.

pub fn is_on_curve(&self) -> Choice

Check if on curve y² = x³ + B.

pub fn from_bytes(bytes: &[u8; 96]) -> CtOption<Self>
