Efficient Hardware Implementation of Ultralightweight RFID Mutual Authentication Protocol

Security and privacy are the two major concerns of radio-frequency identification (RFID) based identification systems. Several researchers have proposed ultralightweight mutual authentication protocols (UMAPs) to ensure the security of the low cost RFID tags in recent years. However, almost all of the previously proposed protocols have some serious security flaws and are vulnerable to various security attacks (full disclosure attack, desynchronization attack, impersonation attack, etc.). Recently, a more sophisticated and robust UMAP: Robust confidentiality integrity and authentication (RCIA)1 [U. Mujahid, M. Najam-ul-Islam and M. Ali Shami, RCIA: A new ultralightweight RFID authentication protocol using recursive hash, Int. J. Distrib. Sens. Netw. 2015 (2015) 642180] has been proposed. A new ultralightweight primitive, “recursive hash” has been used extensively in the protocol design which provides hamming weight unpredictability and irreversibility to ensure optimal security. In addition to security and...
