Title:
On the security of another CRC based ultralightweight RFID authentication protocol

Authors: Seyed Farhad Aghili, Hamid Mala

Abstract:

Design of ultra-lightweight authentication protocols for RFID systems conformed with the EPC Class-1 Generation-2 standard is still a challenging issue in RFID security. Recently, Maurya et al. have proposed a CRC based authentication protocol and claimed that their protocol can resist against all known attacks in RFID systems. However, in this paper we show that their protocol is vulnerable to tag impersonation attack. Moreover, we show that how an attacker can easily trace a target RFID tag. Our analyses show that the success probability of our attacks is “1” while the complexity is only one session eavesdropping, two XORs and one CRC computation.
