Unicom Design And Implementation Of Secure Authentication System Based On Public Key Encryption

SMS(Short Messaging Service) Platform of Shanxi Rural Credit Union(SRCU) is designed for making the financial services in SRCU more humanized and convenient. SRCU can provide much better services for its customers with this platform, so SRCU can improve the service level of financial services.

Using global system for mobile(GSM), code division multiple access(CDMA) to finish designing SMS platform to provide finical services, such as information notification of credit and inquiry business for its customers who have mobile telephone and sign the contract.The basic theory of developing and designing SMS platform development is based on the software engineering theory. using the waterfall development method to develop the platform. After analysis the feasibility of SMS platform development, analysis the demand of SRCU and its customers, according to the demand analysis and some mature SMS platform of commercial bank credit cooperatives, design special SMS platform and implement it.In this thesis, first introduce the background of the SMS platform, SMS development status at home and abroad and the SMS platform feature of other commercial bank, and the main goal of this platform detailedly. Then describe the demands of SMS platform for SRCU and its customers. According to these demand, SMS platform is designed. At the same time design the overall architecture of platform,function module of platform, network architecture of platform, and the database. In the last,implement and test the platform, introduce the implementation of the main modules in this platform, test the function and the performance of the platform.This platform can manage the business in concentrated way although the distribution of SRCR is scattered, and clear the expenses for RCU in different city for the SMS can be queried with different condition. The interface is designed well can receive information from other modules and other system, so it’s is easy to expand this platform if there is new demand.The result of testing platform show that the platform that design in this thesis can meet the basic demand of SRCU and its customers.
