Functions ¶
func PairIsEuqal ¶
func PairingCheck ¶
PairingCheck calculates the Optimal Ate pairing for a set of points.
Types ¶
type G1 ¶
type G1 struct {
// contains filtered or unexported fields
}
G1 is an abstract cyclic group. The zero value is suitable for use as the output of an operation, but cannot be used as an input.
func (*G1) HashToPoint ¶
func (*G1) ScalarBaseMult ¶
ScalarBaseMult sets e to g*k where g is the generator of the group and then returns e.
func (*G1) ScalarMult ¶
ScalarMult sets e to a*k and then returns e.
type G2 ¶
type G2 struct {
// contains filtered or unexported fields
}
G2 is an abstract cyclic group. The zero value is suitable for use as the output of an operation, but cannot be used as an input.
func (*G2) ScalarBaseMult ¶
ScalarBaseMult sets e to g*k where g is the generator of the group and then returns out.
func (*G2) ScalarMult ¶
ScalarMult sets e to a*k and then returns e.
type GT ¶
type GT struct {
// contains filtered or unexported fields
}
GT is an abstract cyclic group. The zero value is suitable for use as the output of an operation, but cannot be used as an input.
func Miller ¶
Miller applies Miller's algorithm, which is a bilinear function from the source groups to F_p^12. Miller(g1, g2).Finalize() is equivalent to Pair(g1, g2).
func (*GT) ScalarMult ¶
ScalarMult sets e to a*k and then returns e.
