Security Issue of Electronic Commerce

In spite of its advantages of lowering the cost, expanding the market, unrestrained by the geographical areas and space, etc, electronic commerce is confronted with the security issue which hinders its widespread application. It must adopt the security technologies (e.g. encription, electronic signature, electronic envelope, electronic certification, and firewall) to provide the participants with the authentication service, access control service, confidentiality service, undeniable service, and other reliable security service. Its security architecture includes support service level, transport level, switching level, and business level. At present, the security scheme mainly involves the security communication protocol, commercial servers supporting secure transactions and electronic payment system, and some problems remain to be resolved.
