High Security Entrance Access Control System Design Using ISO 14443-A Standard

Abstract

RFID has been widely used in high security applications due to its contactless characteristic and security mechanism, such as e-ticket, e-money, e-key and so on. Since magnetic stripe card and traditional Mifare RFID card can be broken, it is a general trend to change them with CPU card. Based on the above fact, an entrance access control system is proposed in this paper using ISO/IEC 14443-A standard to replace some unsecure card. The following measures were introduced: 1, to design a kind of RFID reader which can be easily installed on the entrance; 2, to introduce PSAM card and its security function; 3, to design a security authentication mechanism using random number and 3DES encryption algorithm. With this system, the access control becomes more security and manageable, the proposed system is cost efficient and is successfully used in some companies.
