An indoor location-based access control system by RFID

With the rapid development of wireless and mobile network, traditional access control mechanisms face the new security risk that access data at any place may lead the leakage of the confidential data or bring new attack to the server. Location based access control is proposed to authorize user by consideration the location information of the user. In this paper, a novel indoor access control system is presented to protect the data security in mobile storage device. An Active tag is embedded into the storage device to implement location based access control. We make use of the limited penetration of RF signal to build the security zone, and get user´s location information from the tag and the reader. In order to protect the system and carry out authorization, an authenticate protocol is proposed. The protocol can ensure the anonymity of the tag, and protect the confidential of the data to prevent spoofing attack and replay attack. More important, our system can authorize the user according to user´s location information.
