摘 要: 提出了一种基于固定电话网(PSTN)短消息的证券电子化系统。为了适应股票交易委托的需要,对PSTN的短消息系统进行系统和协议的扩展:这个系统增加了CTSI服务器的交易模块、业务交易网关和专业CP系统。这些扩展满足了股票交易的实时性。在保障交易安全的问题上,该系统采用了终端ID判别、3DES加密等一系列措施。文中详细介绍了该系统的框架、物理拓扑结构、系统功能以及安全性设计。最后对该方案进行了详细的应用上的优缺点分析。 This paper proposes a stock electronic commerce(EC) system based on short message system(SMS) of Public Switched Telephone Network (PSTN). The system expands frame and protocol of the SMS of PSTN in order to meet the needs of stock jobbing: adding exchange module of Chinese Terminal Service Interface(CTSI) server, operationexchange gateway and specialized content provider (CP) system. These expansion satisfies the real-time requirment of stock jobbing. To ensure security of the exchange, the EC system adopts measures of terminal ID distinguishability, 3DES encryption and exclusive serial number. The paper makes a detailed description of system frame, physical topology, system function and security design, including analysis of the merit and disadvantage of applications.
