𝔽(2^m)

CurveFP CurvePrime

𝔽p

data Point Source

Define a point on a curve.

Constructors

Point Integer Integer 
PointO

Point at Infinity

type PublicPoint = Point Source

data CurveBinary Source

Define an elliptic curve in 𝔽(2^m). The firt parameter is the Integer representatioin of the irreducible polynomial f(x).

data CurvePrime Source

Define an elliptic curve in 𝔽p. The first parameter is the Prime Number.

common_curve :: Curve -> CurveCommon Source

Parameters in common between binary and prime curves.

curveSizeBits :: Curve -> Int Source

get the size of the curve in bits

ecc_fx :: CurveBinary -> Integer Source

Irreducible polynomial representing the characteristic of a CurveBinary.

ecc_p :: CurvePrime -> Integer Source

Prime number representing the characteristic of a CurvePrime.

data CurveCommon Source

Define common parameters in a curve definition of the form: y^2 = x^3 + ax + b.

Constructors
