Design And Implementation Of CA-based Internet Bank System

With the rapid development of computer and network technologies, Internet Bank is gradually popularized, which is a finance tool of payment and balance. However Internet Bank is confronted with a variety of risks owing to the character of the Internet, which is open to everyone. PKI ( Public Key Infrastructure) /CA ( Certificate Authority ) System is a basic and key technology that is used to solve the reality, safety and integrality of online exchange. In particular, CA is a necessary and key component of the system.This paper majors in the research and development of Java-based Internet Bank system.Firstly, the Internet Bank system for agricultural bank of AnHui is introducted in this paper. We have analyzed and discussed its function and features. The logical and functional structure of Internet Bank system has been explained particularly. And we divided the system into two parts: CA and business operation of bank.Secondly, this paper has developed CA based on JAAS (Java Authentication and Authorization Service) , and discussed development flow of CA based on JAAS using authentication and authorization, And combined CA with application of Internet Bank, it improve Internet Bank System safety and dependability.Thirdly, this paper has developed the business operation of bank based on J2EE, and divided the module into eight sub-module, and we described the functional structure of each sub-module. We have discussed implementation flow and design methods based on J2EE using querying balance and paying for expense business.This paper finally tests the system's functions. We used the Black Box method in the tests, and analyzed the test results in theory. It is useful to improve the system performance.The Internet Bank system has been applied successfully, achieved the design object and the system is running well.
