文摘We present a multi-signature scheme based on DSA and describes a faireleetronic payment scheme based on improved DSA signatures. The scheme, makes both sides in e-qualpositions during the course of electronic transaction A Trusted Third Party (TTP)is involved in thescheme to guarantee the fairness of the scheme for both sides. However, only during the course ofregistration and dispute resolution will TTP be needed TTP is not needed during the normal paymentstage.
