Addressing NFC Mobile Relay Attacks: NFC User Key Confirmation Protocols
Ali A. Alshehri, Steve A. Schneider · International Journal of RFID Security and Cryptography · 2014
Near field communication (NFC) is a RadioFrequency (RF) technology that allows data to be exchanged between devices that are in close proximity.A relay attack is a general attack against RFID/NFC that manipulates the proximity factor between entities, which is caused by either internal or external attackers.We propose NFC User Key Confirmation Protocols (UKC) to address the NFC mobile relay attack.For proximity proof, the solution is intended for addressing external attackers and for the assumption that the users are honest.The main idea of addressing the relay attack in NFC mobile is by engaging the users for the key confirmation protocol.The key confirmation protocol would be a shared mission between the cryptographic protocol and the end user.The UKC protocols address both entity authentication and proximity proof requirements.We formally verify the protocol using CasperFDR.
