type Group ¶

type Group interface {
	GetRandomElement() *big.Int
	Mul(*big.Int, *big.Int) *big.Int
	Exp(*big.Int, *big.Int) *big.Int
	Inv(*big.Int) *big.Int
}

Group interface is used to enable the usage of different groups in some schemes. For example when we have a homomorphism f between two groups and we are proving that we know an f-preimage of an element - meaning that for a given v we know u such that f(u) = v. Note that this is an interface for modular arithmetic groups. For elliptic curve groups at the moment there is no need for an interface.
