The Research Of Sniffer Technology And The Application In The Unified Login

Nowadays, with the increasing information technology,the business systems of enterprise are growing, and these systems are based on different systems. On the other hand, high-end users have more requires. In order to secure business system,customer set different password to protect their application. That makes lots of problem. Therefore, it is necessary to use a unified login solution to reduce the risk of password. And then, to improve the availability of system and the loyalty and satisfaction of customer to enterprise.There are too many business system in the enterprise, which causes trouble for the maintenance of system. Following the practical requirements, the paper deeply analyzes the requirements of telecommunication and implementation object, and provide a unified login solution. The solution includes mainly four parts. The first part is about the automated login of desktop application. The second part is about the automated login of web application. The third part is about data storage of user and password. The last part is about centralized management. According to the design,the paper deeply studies the login mechanism of different applications,message handling mechanism and method of saving data. To ensure the scalability of system, centralized management is used to manage the behavior of customer.In addition, the paper describes the key technology with regard to the unified login, that is the message sniffer based on system level. The technology is concerned with windows hook, message mechanism, DLL(Dynamic Link Libray) and code injection. According to detailed requirement analysis, the paper provides a design pattern, and then the paper implements the details of every module, and do lots of tests, and analyze the test results.In the end of the paper, the conclusion is made to the paper and provides a creative point of the paper and then points out the follow-up research work.
