Since Low-cost RFID tags have very limited hardware resources, it is difficult to implement an authentication protocol which uses heavy operations such as modern ciphers or hash functions. It has been presented some ultra-lightweight RFID authentication protocols for low-cost RFID tags by using very light operations. Recently, Jeon and Yoon proposed a new ultra-lightweight RFID authentication p...

RFID tag has limited calculation resources and small storage capacity, the wireless communication channel between RFID tag and reader is vulnerable to various malicious attacks. Aimed at these problems, a HMAC-based RFID lightweight authentication protocol is proposed in this paper, and some considerations about protocol implementation are made subsequently. In the new protocol, only the Hash f...

Privacy is a major concern in RFID systems, especially with widespread deployment of wireless enabled interconnected personal devices. In this paper, we consider privacy issues in RFID system where the authorized readers must be able to identify tags without an adversary being able to trace them, and provide a formal security model for privacy in RFID system. Under this model, we analyze the re...

Mobile RFID applications combine RFID technologies and mobile device to create a new convenient application area. However, most of the applications suffer from the security issues due to insecure communication channels among tags, readers and servers. In 2012, Zhou et al. proposed an ECC-based mutual authentication protocol to promote mobile RFID applications security. However, we found their p...

We discuss insider attacks on RFID protocols with a focus on RFID tag privacy and demonstrate such attacks on published RFID protocols. In particular, we show attacks on a challenge-response protocol with IND-CCA1 encryption and on the randomized hashed GPS protocol. We then show that IND-CCA2 encryption can be used to prevent insider attacks and present a protocol secure against insider attack...

RFID (Radio Frequency Identification) technology enables readers to scan remote RFID tags, and label the objects and people to which they are attached. Current cryptographic authentication protocols deployed in heterogeneous environments are often not compatible, or reveal too much information to the RFID readers. To tackle this problem, we introduce the concept of RFID groups and propose a hie...

Radio Frequency IDentification (RFID) systems are gaining enormous interests at industry due to their vast applications such as supply chain, access control, inventory, transport, health care and home appliances. Although tag identification is the primary security goal of an RFID system, privacy issue is equally, even more, important concern in RFID system because of pervasiveness of RFID tags....

RFID systems are widely used in various applications, and attaching RFID tags to objects are increasing. Recently, Xie et al. defined RFID seeking concept which is finding a lost tag in a blind spot or a specified tag among lots of similar ones and proposed a lightweight RFID seeking protocol. Their protocol provides security and privacy against most of common malicious attacks. However, since ...

Radio Frequency Identification (RFID) technology is an automated identification technology which is widely used to identify and track all kind of objects. However, it is a challenging task to design an authentication protocol because of the limited resource of Lightweight RFID tags. Recently, a lightweight RFID authentication protocol and an ownership transfer of RFID tags are presented by Kuls...

Nowadays, plenty of radio frequency identification (RFID) systems have been proposed and used in the real world for convenience. An RFID system requires advanced properties of confidentiality, indistinguishability, forward security and mutual authentication to provide a higher security level. Safkhani et al. proposed a hash-based authentication protocol for RFID systems. Though their protocol p...
