he credibility of the store work and service quality is actually the key to the success of emerce. Ⅲ .the key to development of electronic merce Emerce in the telemunications work to develop. Therefore, the advanced puter work infrastructure and telemunications policy easing the development of electronic merce has bee a prerequisite. Currently, tele services, high prices, limited bandwidth, the service is not timely or not reliable and so the development of emerce has bee a constraint. Speed up the construction of telemunications infrastructure, to break the telemunications market monopoly, introduce petition mechanism to ensure fair petition in the telemunications business, to promote working, ensure to provide users with lowcost, highspeed, reliable munications services is a good construction target work environment, but also all of the world mon task. Emerce the most prominent problem is to solve the online shopping, trading and clearing of security issues, including the establishment of emerce trust between all the main issues, namely the establishment of safety certification system (CA) issues。 Emerce Information Security Problems Ⅰ .
