Abstract
Utilizes directed signature and blind signature to put forward a new digital signature scheme based on ElGamal public key system and analyses its security. Also proved the scheme feasibility through the knowledge of primary math theory. The scheme has the genuine characteristic of anonymity of e\|commerce.
