【摘要】 本文研究的内容是如何开发高效安全的“企业银行系统”。所谓企业银行系统，是企业通过计算机网络与银行的业务主机相连接，并以在线方式进行各种支付结算活动。本文对“企业银行系统”的构建进行了描述，并着重探讨了其中的通讯、安全加密、数据库接口、业务监测等。 “企业银行系统”采用了基于PC-MODEM-Telephone的通讯系统。在本系统中，企业端和银行端之间需要字节流数据的传输。为了实现可靠的字节流数据的传输，借鉴MODEM文件传输协议，设计了自己的MODEM通讯协议。新协议增强了对接收、发送过程的控制，提高了传输的可靠性，调用接口更加灵活。协议的软件实现符合TCP／IP和ISO／OSI参考模型对网络软件分层设计的规范，有较好的独立性、可移植性和通用性，有非常大的市场推广价值。 电子支付中最大的问题就是要保证交易的安全。本系统的安全加密子系统综合运用了网络安全领域的最新发展成果，如非对称密钥加密及身份验证、数字签名等技术，在对系统安全问题进行分析的基础上，设计了一整套在线支付安全加密解决方案，为用户提供了一个安全、可靠、信用的交易环境。 交易的各个环节都涉及到对数据库的访问。数据库接口子系统设计了一个API函数集，该函数集把各个部分对数据库的访问综合考虑后进行封装，降低了系统对数据库平台的依赖性，优化了整体的性能。 IPC是多任务操作系统的一个重要机制。业务监测子系统利用UNIX的IPC，将业务处理进程状态以消息方式发送，由特定进程接收后将他们排队并显示到指定的终端上，系统管理员可据此了解进程的当前工作状态，增加了后台业务处理的可观性和可控性。 当前，电子商务的发展举世瞩目，本课题研究的在线电子支付系统是电子商务中的一个重要内容。本课题的研究开发的成功，不但提高了北京化工大学学位论文银行的服务水平，方便了企业，对电子商务在我国的发展做出了自己的贡献。关键词:电子商务电子支付通讯网络安全更多还原

【Abstract】 The disquisition discussed the research and construction of a safe, efficient "Enterprise-Bank Online Payment System", which can help enterprises do bank payment work online through computer network.. The subject focused on four points: Communication, Security and Encryption, Database Interface and Business Inspection.The communication is base on PC-MODEM-Telephone. In order to transmit bytes stream reliably between Bank and Customer, which is required in this system, A modem communication protocol was designed , with the existing File Transfer Protocols(FTP) as a reference. The new protocol strengthened control to the process of send and receive, enhanced the reliability of transmission, and improved the flexibility of call interface. The software realization is in accordance with the TCP/IP and ISO/OSI reference model, thus the software is independent, portable and versatile, and is of great market value.Security is one of the biggest problem in such a system. On the basis of thorough analyzation of the risks, a set of online-payment security and encryption resolution scheme is designed , in use of the latest achievement in network security such as un-symmetric encryption algorism ,identification protocol, and digital signature etc, which provides a safe, reliable and creditable deal environment for users.Database is accessed everywhere. An Application Programming Interface (API) functions set encapsulating the database has been defined after comprehensive consideration which decreased the dependence on a certain database platform and optimized the overall performance.InterProcess Communication(IPC) is an important mechanism inmulti-task operating system. With the IPC of UNIX, the Monitoring sub-system sends the process status information as messages , which is queued and displayed on a nominal terminal , by which the system administrator can find out what the processes are doing currently.E-Commerce has made great progress recently. The Electric Online Payment System, which is studied in this disquisition, is one of the most important part in e-commerce. The success of the system will improve the service of bank, which facilitates the payment work of enterprises, and have contributed to the development of e-commerce in our country.更多还原
