Low Cost Minimal Mutual Authentication Protocol for RFID

The reason for radio frequency identification usage is its potential for pervasive id tracking in logistic applications. It could objectively improve efficiency of items´ identification due to contact-less detection. Several attempts have been made to implement e-payment and e-passport. Such system requires high security mechanism however they are not secure enough for personal data, in term of privacy. Efficiency is quite critical issue during RFID used for massive data collection system, such as e-passport or logistic system. The cost for RFID tags is decreasing, however, it is still relatively high compared with other id tracking means such as optical barcodes. Here comes a new issue how we guarantee the security with low trade-off in both cost and efficiency in security required system. The proposed protocol is a minimal mutual authentication protocol for RFID. The motivation of this work is the growing concern for security requirements as well as minimizing the cost of the overall system operating within a given security protocol.
