Functions

Types

type GroupChecker

type GroupChecker interface {
	kyber.Point
	IsInCorrectGroup() bool
}

GroupChecker allows to verify if a Point is in the correct group or not. For curves which don't have a prime order, we need to only consider the points lying in the subgroup of prime order. That check returns true if the point is correct or not.

type Suite

type Suite struct {
	// contains filtered or unexported fields
}

func (*Suite) G1

func (s *Suite) G1() kyber.Group

func (*Suite) G2

func (s *Suite) G2() kyber.Group

func (*Suite) GT
