%X In this paper,the demand of an e-commerce system security and the realizing process of an e-signature tech- nology as the essential key technology in the safety control are elaborated;the insufficiency in current e-signature reali- zing process is pointed out;based on digital encryption and information hiding,an improving thinking and some reali- zing schemes for the techniques of e-signature are given;a creative new idea to guide the selection among the e-signa- ture technical schemes with a"safety/speed ratio"digital signature strength theory is proposed;and the developing di- rection of an e-commerce security technology is pointed out.
