The solution of problem about merchandise flow, payment flow and information flow,is the key to implement business on networks.The transmission of payment flow is the hot problem on E-Commerce.How to make the electronic payment to convey instantly and safely over non-safety networks, is the most important issue.Security techniques is researched for E-Commerce .By the way, the paper present a payment system schedule for the BtoB mode, which is abided by the principle of SET protocol, and is authorized by CFCA.This paper addresses the architecture of electronic payment systems and relevant payment information security. On the architecture, it tries to build up the operable and extensible system, which combines kinds of payment way with security server infrastructure. On the other hand, information security over open networks includes four main parts: data confidentiality, integrity, non-repudiation and identity authentication.Electronic payment system should protect payment information from being destroyed. In the end, the security properties of the schedule, SET protocol and SSL protocol are analyzed.
