Abstract: According to the low cost and convenient application demand of current intelligent security system, a novel identification system is designed in order to improve the convenience and stability of RFID in practical application based on RFID secondary authentication and encryption.The system is primarily come out of the key storage partition of MIFARE-S50 and any data partition,used the irreversibility of hash code algorithm, and UID is used as the authentication part in the key of intelligent recognition system.Only when the data and UID are authenticated twice by the system, then the smart card can be recognized and made relevant identification actions. At the same time, if system encounter a copy card, it can effectively identify and prevent the authentication.The system supports three working modes that are the registration mode, operating mode and logout mode, which can effectively ensure the privacy and information security of users.Actual experimental results show that the system has high security,good stability,and is convenient and easy to operate. And it has high application and practical value,,and can be used in schools,communities,,companies and other medium-sized RFID intelligent security systems to limit the invasion of illegal personnel.
