An Ultra Lightweight Mutual Authentication Protocol for Low Cost RFID Tags
"RFID (Radio Frequency IDentification) is emerging as an important tool in the field of automatic identification technologies. The universal deployment of RFID devices may expose new security and privacy risks. These risks are the main obstacle for successful deployment of RFID tags. Since, the traditional cryptographic approach is not suitable for the RFID tags due to its limited computation resources and small storage capacity. This paper proposes an effective and efficient ultralightweight mutual authentication protocol, to achieve stronger security and privacy by using only simple bitwise operations (e.g. XOR, modulus addition)."
