In this paper, an important problem that the security of e-commerce system has become one of the core issues and the main bottlenecks which constraints the development of e-commerce is pointed out; the demand of an e-commerce system security and the realizing process of an e-signature technology as the essential key technology in the safety control are elaborated; the insufficiency in current e-signature realizing process is pointed out; based on digital encryption and information hiding, an improving thinking and some realizing schemes for the techniques of e-signature are given; a creative new idea to guide the selection among the e-signature technical schemes with a ldquosafety/speed ratiordquo digital signature strength theory is proposed; and the developing direction of an e-commerce security technology is advanced.
