RFID-tags are becoming very popular tools for identification of products. As they have a small microchip on board, they offer functionality that can be used for security purposes. This chip functionality makes it possible to verify the authenticity of a product and hence to detect and prevent counterfeiting. In order to be successful for these security purposes too, RFID-tags have to be resista...

Radio frequency identification technology is becoming ubiquitous, and as an unfortunate side effect, more and more authentication solutions come with more security issues. In former contributions, the authors introduced a solely hash-based secure authentication algorithm that is capable of providing protection against most of the well-known attacks and performs exceptionally well even in very l...

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...

The term "Internet of Things (IoT)" expresses a huge network of smart and connected objects which can interact with other devices without our interposition. Radio frequency identification (RFID) is a great technology and an interesting candidate to provide communications for IoT networks, but numerous security and privacy issues need to be considered. In this paper, we analyze the security and ...

In side channel analysis, an attacker utilizes some legitimate function queries in order to collect the corresponding responses of a cryptographic system while it is functioning in a normal mode. If those responses reveal some unwanted information about the secrecy or privacy, this leakage is called side channel information and these responses are called side channels. In this respect, careless...

In a world with RFID carriers everywhere, the coexistence proof of multiple RFID-tagged objects shown at the same time and the same place can become a very useful mechanism and be adopted in many application areas such as computer forensics, evi-dences in law, valuables security, and warning or notification systems, etc. In order to support the correctness of derived proofs, it is necessary to ...

Authentication has an important role in many RFID applications for providing security and privacy. In this paper we focus on investigating how RFID can be used in product authentication in supply chain applications and a review of existing approaches is provided. The different categories of RFID product authentication approaches are analyzed within the context of anticounterfeiting and fields w...

Radio frequency identification (RFID) is a powerful technology that enables wireless information storage and control in an economical way. These properties have generated a wide range of applications in different areas. Due to economic and technological constrains, RFID devices are seriously limited, having small or even tiny computational capabilities. This issue is particularly challenging fr...

Retrieval of texture images, especially those with different orientation and scale changes, is a challenging and important problem in image analysis. This paper adopts spiking cortical model (SCM) to explore geometrical invariant texture retrieval schemes based on Discrete Cosine Transform (DCT) coefficients of pulse images. The series of pulse images, outputs of SCM, have a robust talent for e...

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...
