The Security Research Of RFID Technology-based Campus Card System

Terms of the functions from the campus card, campus card mainly as anelectronic wallet and identity of two functions. Therefore, the campus card system outthere is common information management system of information security risks thatexist outside the campus, there are still risks of information security card, campuscard balance in the databases and other sensitive data security risks as well as insupermarkets, schools, campus room card spending process, logistics managementsystem as third-party payment platform to deny the existence of transaction securityrisks.To this end, the article in the current development of the campus card systembased on the simple introduction of RFID technology used in the article, dataencryption and database security system for a brief overview of the research to lay thetechnical foundation behind; then RFID technology-based campus card systemstructure and the specific function of a simple analysis based on the existence of thesecurity system from a database encryption, transaction repudiation, campus card andcampus card data security management security is analyzed ; Finally, based on RFIDtechnology for the campus card system, the existence of security risks, by usingtwo-way authentication mechanism campus card, public key encryption and databasestored procedures encryption to ensure security of the system.Among them, the stored procedure in the database encryption using DESsymmetric encryption algorithm and the encryption key stored in the teacher-studentcampus card; in two-way authentication mechanism, through the random number withthe hash function used to ensure that each certification is different to reduce thesecurity risk of replay attacks; transactions in the transaction process deny securityrisks, the use of public key encryption algorithm, in the supermarket managementsystem to save the private key by the Logistics management System ciphertextencrypted transactions, as transactions evidence, thereby reducing the transactionprocess the transaction repudiation risk.
