Radio Frequency IDentification (RFID) systems are getting pervasively deployed in many daily life applications. But this increased usage of RFID systems brings some serious problems together, security and privacy. In some applications, ownership transfer of RFID labels is sine qua non need. Specifically, the owner of RFID tag might be required to change several times during its lifetime. Beside...

Cloud based RFID authentication is becoming a large area of interest among researchers and engineers these days. However, there is not much attention given to the RFID authentication concern. Most of the work done on this issue till now has its focus on RFID functionality without considering security and privacy. Classical RFID authentication schemes do not meet the security and privacy require...

Relay attacks are a major concern for RFID systems: during an authentication process an adversary transparently relays messages between a verifier and a remote legitimate prover. We present an authentication protocol suited for RFID systems. Our solution is the first that prevents relay attacks without degrading the authentication security level: it minimizes the probability that the verifier a...

RFID technology is a system which uses radio frequency to transmit data. Data transmission between Tags and Readers is wireless which can be easily eavesdropped by adversary. Due to security and privacy reasons, various authentication protocols proposed. In this paper, we cryptanalyze two different RFID authentication protocols and it is shown that either of them have some weaknesses. In 2014, ...

Radio Frequency Identification (RFID) tags, due to their ability to uniquely identify every individual item and low cost, are well suited for supply chain management and are expected to replace barcodes in the near future. However, unlike barcodes, these tags have a longer range in which they are allowed to be scanned, subjecting them to unauthorized scanning by malicious readers and to various...

Choi et al. recently proposed an efficient RFID authentication protocol for a ubiquitous computing environment, OHLCAP(OneWay Hash based Low-Cost Authentication Protocol). However, this paper reveals that the protocol has several security weaknesses : 1) traceability based on the leakage of counter information, 2) vulnerability to an impersonation attack by maliciously updating a random number,...

In this paper, we explore a new direction towards solving the identity authentication problem in RFID systems. We break the RFID authentication process into two main problems: message authentication and random number generation. For parties equipped with a good source of randomness and a secure cryptographic primitive to authenticate messages, the literature of cryptography is rich with wellstu...

In this demo, we present the realization and evaluation of a wireless hardware prototype of the previously proposed RFID authentication protocol “Ff”. The motivation has been to get as close as possible to the (expensive) construction of a wafer and to analyze and demonstrate Ff ’s realworld feasibility and functional correctness in the field. Besides showing Ff ’s feasibility, our objective is...
