METHOD FOR SECURITY IN RFID TAG, APPARATUS FOR SECURITY OF RFID TAG AND METHOD FOR SECURITY IN RFID ENVIRONMENT

摘要

A method for security in an RFID tag, a security apparatus of the RFID tag, and a method for security in an RFID environment improve reliability of security by authenticating a database server and transmitting the tag information corresponding to query to an RFID reader. A query from an RFID reader(100) is received. An ID showing the RFID tag(110) and a tag random number which shows generation in the RFID tag are transmitted by the RFID reader and are delivered to the predetermined database server(120). The random number and the predetermined operation result corresponding to the database server delivered from the database server are received. The database server is authenticated as a normal server based on the received random number and the operation result. The tag information corresponding to the query is transmitted to the RFID reader.
