City Pass Card System Security Architecture And Design

The Chengdu city IC card system takes IC card accounts settlement center of Chengdu as a core and various professions (public transit, taxi, running water, coal gas, etc.) as the sub center and each charge terminal and supplementing inquiring with money terminal as the information point to construct the construction enterprise charge network. It is constructed the city non-profit organization like bus, the residential quarter managing (refers to running water, coal gas management), the subway, the taxi, the parking lot, the curb parking spot, the highway bridge, the park, etc. by the sole IC card (the double contact surface CPU card) as the payment means of savings card, by public communication network as the tie of linking and by Modernized information management system taking computer system as information processing method. On the one hand enhances service efficiency and the working efficiency, and in common use and facilitating citizens, improving the service quality in the whole city. On the other hand fast automatically processes Operation information and settling account accurately of every profession in the IC card system ensuring every profession and trade interests and offering the macro adjustments and controls of the city and scientific DSS for construction of the city. The safe system of IC card system of Chengdu are formed by four parts:Trade system on the basis of the safe system of Ministry of Construction; the data security system on the basis of back up technology which includes redundancy of the data and tape technology; network security system on the basis of the technology of fire wall; security system of communication on the basis of the encryption. The thesis systematically analyzes and designs from such respects as the security of the system, dependability and economy. In terms of system engineering, fully considers the coordination and cooperation of each component of the safe system, in the hope of making four parts form an intact system. The construction of the city IC card system concerns the daily life of the masses of common people,The financial order and finance safety of the...
