Design And Research On Security Of Campus Cards System

Universities in our country are performing a profound social change, and the change gives universities the most convenient condition to use social resources, which bring more difficulty to universities to manage campus well. Because more and more information management systems applied, things become more and more complex, and these things need to be storage and dispose. If the old manual management is still work, these systems can't cooperate each other, and the campus business can't be disposed effectively, so, this can't meet the demand of the change. The emergence of "Campus Cards System" can resolve these problems. To construct "Campus Cards System", it must resolve two problems, the first one is the security, and the other is the architecture.According to these questions, the paper makes a profound analysis in "Campus Cards System" scheme that designed by some technology Companies and universities in our country, and makes an emphases study on the architecture scheme and security of the "Campus Cards System" by analyzes disadvantage and advantage of different sorts of scheme, then presents an integrated "Campus Cards System" scheme. At the aspect of system's architecture, According to the information and experience of developing of BAODE institute, descript the function and descript the active chart absolutely. According to the most of the develop tool of campus cards system explain the develop platform. At the aspect of system's security, based on some famous cryptogrammic arithmetic, the paper expand a method which contains traditional cryptogrammic arithmetic and modern cryptogrammic arithmetic to get key management, the principle is that cryptogrammic arithmetic generate key and modern cryptogrammic arithmetic (PKI) distribute key. After do this, the paper introduce the digital signature which used in other domain such as e-commerce into "Campus Cards System" then design the campus CPU card key management . The scheme can balance the problem in "Campus Cards System" which makes more emphases on consume system than identity authentication and possess value in security trade and identity authentication in "Campus Cards System". The scheme presented by the paper has general characteristic, it possess practical use and reference value to any "Campus Cards System" in any university.
