Abstract
Progression of the internet technologies has led to the emergence of internet of things (IoT). One of the familiar deployment of IoT is through radio-frequency identification (RFID) technology. In recent times, RFID based systems are one of the most widely spread applications for tagging and keep tracking purposes in IoT deployment. This is due to their powerful features compared to their counterparts of similar techniques such as barcodes. In contrast, radio-frequency identification systems suffer from various attacks and security threats. The wireless channel used for communication is responsible for the majority of these vulnerabilities. In this paper, we propose a new radio-frequency identification authentication protocol based on elliptic curve cryptography (ECC) to eliminate these vulnerabilities. In addition, we use elliptic curve Diffie-Hellman (ECDH) key agreement protocol to generate a temporary shared key used to encrypt the later transmitted messages. Our protocol achieves a set of security properties likes mutual authentication, anonymity, confidentiality, forward security, location privacy, resistance of man-in-the-middle attack, resistance of replay attack and resistance of impersonation attack. We implement our proposed protocol in real RFID system using Omnikey smartcard reader (Omnikey 5421) and NXP Java smartcards (J3A040). Implementation results shows that our proposed protocol outperform in term of time complexity as compared to other similar protocols and requires less number of operations.
