Types

type Alice

type Alice[A any, B any] struct {
	// contains filtered or unexported fields
}

func NewAlice

func NewAlice[A any, B any](curve *curves.Curve, output *dkg.Output, sender MTASender[A, B]) *Alice[A, B]

NewAlice creates a party that can participate in protocol runs of DKLs sign, in the role of Alice.

func (*Alice[A, B]) Output

func (alice *Alice[A, B]) Output() *AliceOutput

func (*Alice[A, B]) Step2

func (alice *Alice[A, B]) Step2(commitment schnorr.Commitment, a A) (curves.Point, curves.Scalar, curves.Scalar, *schnorr.Proof, B)

func (*Alice[A, B]) Step4

func (alice *Alice[A, B]) Step4(proof *schnorr.Proof)

type AliceOutput

type AliceOutput struct {
	R       curves.Scalar
	X1      curves.Scalar
	K1      curves.Scalar
	PkJoint curves.Point
}

type Bob

type Bob[A any, B any] struct {
	// contains filtered or unexported fields
}

func NewBob

func NewBob[A any, B any](curve *curves.Curve, output *dkg.Output, receiver MTAReceiver[A, B]) *Bob[A, B]

NewBob creates a party that can participate in protocol runs of DKLs sign, in the role of Bob. This party receives the signature at the end.
