Card Security System Architecture Research

In recent years, with the impulse of the strategy "revitalize the nation through science and education","Digital Campus"constructions in higher school have developed rapidly. In digital campus, as the"Campus E-card System" has something to do with learning and living and all aspects of conduct activities, it became a constructive foundation and keystone in campus. Constructions of "Campus E-card System" also became an uncommon opportunity to further enhance the level of information and to build digital campus.The design of "Campus E-card System" must comply with the figure of the overall design of the campus thought. This system is not only operated as the consumer system, but also has the management capabilities, combining with the school management information system. This system has identification functions; it could establish a unified identity information library. It is not only to meet the needs of teachers and students in function and use, but easy to manage with high security, it is also to provide better services to ensure safety in all aspects of performance, and to prevent and avoid loss suffered by any possible attack and damage.The "Campus E-card System" has become an important foundation of digital campus constructions and symbol of the modernization of school management, but also to the whole digital campus core applications. "Campus E-card System" should not only provide the financial platform for internal consumption, but also provide the data platform for digital campus, so the safety of "Campus E-card System" in the process of design and implementation must be the focus of consideration.Chapter 1 of this thesis briefly introduce the history of development of campus E-card, including the status of development at home and abroad, describe the applications of campus E-card system in the real-life , and security of this system in aspect of design and use.In chapter 2, it briefly introduces the basic profile of digital campus, describes the importance of E-card system as foundation engineering in digital campus, and also describes the function of E-card system, including the electronic wallet, identity recognition, as well as some functions of aspects of integrated searches.In chapter 3, it describes the basic situation of subsystems of campus E-card in detail.In chapter 4, it introduces the system architecture of E-card system in aspect of network architecture and system platform.In chapter 5, it introduces an information system security model which applies to campus E-card system in accordance with the definition of the model.In chapter 6, it produces researches of card's design, use and management security.In chapter 7, it produces researches of encryption algorithm, secret-key's produce, and its use, management security.In chapter 8, it analyzes and discusses the relevant security of E-card system, including security of data transmission and data storage.In chapter 9, full thesis is summarized.
