METHOD OF MUTUAL AUTHENTICATION AND SECURE DATA COMMUNICATION IN RFID-SYSTEM

摘要

A method for mutual authentication and secure data communication in an RFID(Radio Frequency IDentification) system is provided to offer high security reliability by realizing bidirectional authentication between a tag and a reader, and secure all information in entire section from the authentication and the data communication by making the data communication safe after the authentication. The reader recognizes an ID of the tag. The reader authenticates the tag(S200). The tag authenticates the reader(S300). The data communication between the tag and the reader is performed with communication security(S400). The ID and key information of the tag are stored in a RAM or a security EEPROM(Electronically Erasable Programmable ROM) of the tag, and a tag database connected to the reader through the network.
