With the continuous progress and development of society, the original consumption and management models of schools can no longer adapt to the new development requirements. Based on the current status quo, the “campus all-in-one card system” came into being. The so-called “all-in-one card” refers to the use of cards in schools where cash, tickets, or identification is required. This management model replaces the traditional consumption management model, bringing efficiency, convenience and safety to school management.
1. The practical significance of the campus all-in-one card
Student life: Students have student IDs, meal cards, borrowing cards, bank cards, telephone cards, etc., ranging from three or four to six or seven, which brings a lot of inconvenience to students’ daily life.
Campus management: Each of the existing systems has independent authentication methods and consumption methods; schools cannot achieve unified management, and resources cannot be rationally used and shared.
Banking services: colleges and universities are becoming key customers of banking services. The campus card will be a better and more convenient way for banks to serve and profit from campuses. Banks will also use their best services Cultivate and compete for potential customer groups on campus.
Telecommunications services: The competition in the telecommunications industry is unprecedentedly fierce, and campuses have become another focus of their competitive strategy, not only to serve the campus, but also hope to obtain more potential customers and more benefits in this way.
2. Technical conditions of the campus all-in-one card
Mature network technology: The one-card system is based on the campus network and uses advanced network security technology to ensure the integrity, stability and security of various data transmitted on the network.
Advanced card technology: The gradual maturity of card application technology (including system software and card equipment) provides the application technology foundation for the all-in-one card system.
Secure key system: 128-bit international standard DES encryption algorithm and other multi-layer security authentication methods provide the basis of security technology.
3. Functions that can be realized by the campus card
Daily consumption: To achieve all consumption on campus, only one campus card is required for consumption in student canteens, faculty restaurants, shops, supermarkets, bookstores, barber shops, community service centers, laundry shops, photocopy shops, and various venues.
Identity Recognition: Realize all the identity recognition functions on campus, such as library access, book borrowing, computer center, gymnasium, swimming pool, playground, equipment department, dormitory access, teachers’ attendance at get off work, and students’ attendance at get out of class.
Information management: realize the electronic and all-in-one card management of all management work on campus, such as campus card management, campus business management, financial charge management, educational administration management, library management, dormitory management, computer room billing management, water-saving control management, medical management, etc. .
4. Introduction of Dike Yuanwang Campus Card System
The Dico Yuanwang campus card system is based on the school’s existing campus network. It uses the physical separation of bank cards and campus cards. Each application subsystem exists as independent modules and runs on the card platform. All relevant data And information is managed uniformly in the system to realize centralized storage and global sharing of data. The Dico Yuanwang campus card system is no longer a simple consumer card, but a card system that integrates identity recognition, information management, financial services and other functions. It can truly realize “one card in hand, travel all over the campus.” “.
On the basis of the existing campus network, the campus all-in-one card system uses advanced network technology to make all all-in-one card related data and information independent of the existing campus network environment. At the same time, the internal data of the all-in-one card is encrypted with three layers of 128-bit DES and the system encryption key is dynamic. The storage method (a new encryption key is generated every time the system is started) ensures the security of data transmitted on the network. The whole system adopts a multi-layer application structure combining B/S and C/S. The overall structure of the system is shown in Figure 1:
1. Central server
One card platform operating system selection: Sun Solaris, SCO Unix
Platform database selection: Oracle 8i / 9i
The central host adopts dual-system hot backup (mainstream servers such as SUN, HP, IBM, DELL, etc. can be used according to the school situation)
2. Subsystem server
Operating system selection: Windows 2000 Server
Platform database selection: SQL Server 2000
3. Card selection
Bank card: Use a debit card with a unified bank style issued by the bank, and the card issuance and maintenance are carried out by the bank.
School card:
Use contactless IC card as the school electronic wallet, which can be divided into 16 independent wallets;
The campus’s iconic patterns are beautifully printed by Kaji;
Print photo, student number, name, department, class and other information on the front;
4. Capital flow diagram
The overall capital flow diagram of the campus all-in-one card system is shown in Figure 2:

6. Security analysis
From the card itself to the actual application process, data storage, network communication and other links that may involve security, the system conducts security analysis and adopts a variety of security prevention strategies.
1) Network security: Adopt advanced network technology and three-layer exchange technology to make all card system related data flow independently on the existing campus network, and carry out three-layer standard 128-bit DES encryption, between the data center server and the client All have internal data verification and authentication, and the system key is stored in the memory and cannot be read, and a new key will be generated every time the system is started.
2) Device security: The device has the function of anti-counterfeiting card, the card and the device are mutually authenticated, each transaction record of the POS machine has a serial number, and all transaction accounts are equipped with a verification function; the POS machine adopts a dual CPU mechanism (one responsible for Read and write cards, the other is responsible for data communication) and dual FLASH data storage methods.
3) Card security: PHILIPS company’s Mifare One card is used as an electronic wallet. The card itself has very high security. The Mifare One card takes a long time to physically decipher; the card is divided into 16 sectors, and each sector has its own card reader. Password and card writing password; the data stored in the card is encrypted with a three-layer 128-bit DES encryption algorithm.
4) Data security: Make full use of the access control of the Oracle database itself to ensure the security of the central database, and check the important data tables in the central database to prevent tampering; the system uses tape backup, dual-system hot backup, and data Methods such as automatic storage and off-site backup further ensure the security of all-in-one card data.
