Many RFID authentication protocols have been proposed to provide desired security and privacy level for RFID systems. Almost all of these protocols are based symmetric cryptography because of the limited resources of RFID tags. Recently Cheng et. al have been proposed an RFID security protocol based on chaotic maps. In this paper, we analyze the security of this protocol and discover its vulner...

Passive 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...

Radio Frequency Identification (RFID) and biometric technologies saw fast evolutions during the last years and which are used in several applications, such as access control. Among important characteristics in the RFID tags, we mention the limitation of resources (memory, energy, ...). Our work focuses on the design of a RFID authentication protocol which uses biometric data and which confirms ...

Security and privacy of RFID systems have become very important issues along with their increasing applications. Recently, Jeon and Yoon proposed a new ultra-lightweight RFID authentication protocol(RAPLT) using merge and separation operations. Since their protocol uses very lightweight bitwise operations: XOR, merge, and separation operations, it will be suitable for the applications using low...

Privacy of RFID systems is receiving increasing attention with the progress of Internet of Things. There are a number of challenges in providing privacy and security in the RFID tag due to the limited computation ability of low-cost RFID tags. Many research works have already been conducted using hash functions and pseudorandom numbers to design the RFID protocol. But few of them involve the de...

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...

Although Radio Frequency IDentification (RFID) systems promise a fruitful future, security and privacy concerns have affected the adoption of the RFID technology. Several studies have been proposed to tackle the RFID security and privacy concerns under the assumption that the server is secure. In this paper, we assume that the server resides in the cloud that might be insecure, thus the tag’s d...

Out of the large number of RFID security protocols proposed in recent years none have proven to be truly secure and the creation of a truly secure security protocol for systems employing low cost RFID tags remains an open problem. In this paper we develop and present a RFID security protocol which not only allows mutual authentication and secure transmission of data between the reader and tag b...

RFID tags will exist pervasively in our daily life in a near future. In RFID systems, privacy and security are of critical importance to avoid potential tracking abuse and privacy violations. Many protocols have been proposed to address privacy and security issues in RFID systems. Physical attacks receive few considerations from the current research. Through physically attacks, attackers can ge...
