The Design And Implementation Of Dynamic Password System Based On Multi-Level Management

With the development of computer technology and globalization of information, the security of Internet network has increasingly become the focus of attention of the relevant scholars and computer users. Authentication service is used to identify the status of the two sides of the network, and it is the first line of defense for a security system, and has a great significance in the information security theory and technology. Dynamic password authentication which makes up the deficiencies of traditional password authentication is a more secure authentication mechanism.Dynamic password system currently in use affected the promotion and application of dynamic password system because there are some problems such as the conflict of node identity, secure communications between nodes and service access control. To solve the above problems, we designed and implemented dynamic password systems based on multi-level management, adding a third-party management server in collaboration with the dynamic password authentication,which make up the shortcomings of general dynamic password system to achieve security authentication.This paper first studied the dynamic password technology, analyzed the dynamic password's authentication principle, introduced the dynamic password system's management platform and analyzed the problems of general dynamic password system; then to solve the above problems, this paper presented dynamic password system based on multi-level management, simultaneously introduced the framework, management pattern, management flow, software architecture, development criterion, the implement of the basic functions of the new system and the analysis of system failure probability; Finally, introduced the design and implement of the three core nodes in the new system, including center management server, communication management server and authentication server.
