Security analysis of an ultra‐lightweight RFID authentication protocol for m‐commerce

Nowadays, many people perform their commercial activities, such as electronic payment and electronic banking, through their mobile phones. Mobile commerce (m‐commerce) refers to manipulating electronic commerce (e‐commerce) by using mobile devices and wireless networks. Radio‐frequency identification (RFID) is a technology which can be employed to complete payment functions on m‐commerce. As an RFID subsystem is applied in m‐commerce and supply chains, the related security concerns are very important. Recently, Fan et al. have proposed an ultra‐lightweight RFID authentication scheme for m‐commerce (ULRAS) and claimed that their protocol is efficient enough and provides a high level of security. In this paper, we show that their protocol is vulnerable to secret disclosure and reader impersonation attacks. Finally, we improve it to a protocol that is resistant to the attacks presented in this paper and the other known attacks in the context of RFID authentication. We further analyze the security of the improved protocol through the Burrows–Abadi–Needham logic (BAN‐logic). Moreover, our proposed improvement does not impose any additional workload on the RFID tag.

ECC-Based RFID Authentication Protocol

The radio frequency identification (RFID) technology has been widely used so far in industrial and commercial applications. To develop the RFID tags that support elliptic curve cryptography (ECC), we propose a scalable and mutual authentication protocol based on ECC. We also suggest a tag privacy model that provides adversaries exhibiting strong abilities to attack a tag’s privacy. We prove that the proposed protocol preserves privacy under the privacy model and that it meets general security requirements. Compared with other recent ECC-based RFID authentication protocols, our protocol provides tag privacy and performs the best under comprehensive evaluation of tag privacy, tag computation cost, and communications cost.

Novel Trusted Hierarchy Construction for RFID Sensor–Based MANETs Using ECCs

In resource‐constrained, low‐cost, radio‐frequency identification (RFID) sensor–based mobile ad hoc networks (MANETs), ensuring security without performance degradation is a major challenge. This paper introduces a novel combination of steps in lightweight protocol integration to provide a secure network for RFID sensor–based MANETs using error‐correcting codes (ECCs). The proposed scheme chooses a quasi‐cyclic ECC. Key pairs are generated using the ECC for establishing a secure message communication. Probability analysis shows that code‐based identification; key generation; and authentication and trust management schemes protect the network from Sybil, eclipse, and de‐synchronization attacks. A lightweight model for the proposed sequence of steps is designed and analyzed using an Alloy analyzer. Results show that selection processes with ten nodes and five subgroup controllers identify attacks in only a few milliseconds. Margrave policy analysis shows that there is no conflict among the roles of network members.

Radio frequency identification: technologies,applications, and research issues

A radio frequency identification (RFID) system is a special kind of sensor network to identify an object or a person using radio frequency transmission. A typical RFID system includes transponders (tags) and interrogators (readers): tags are attached to objects/persons, and readers communicate with the tags in their transmission ranges via radio signals. RFID systems have been gaining more and more popularity in areas such as supply chain management, automated identification systems, and any place requiring identifications of products or people. RFID technology is better than barcode in many ways, and may totally replace barcode in the future if certain technologies can be achieved such as low cost and protection of personal privacy. This paper provides a technology survey of RFID systems and various RFID applications. We also discuss five critical research issues: cost control, energy efficiency, privacy issue, multiple readers' interference, and security issue. Copyright © 2006 John Wiley & Sons, Ltd.     

RFID network planning based on improved brain storm optimization algorithm

In order to improve the service quality of radio frequency identification (RFID) systems, multiple objectives should be comprehensively considered. An improved brain storm optimization algorithm GABSO, which incorporated adaptive learning operator and golden sine operator into the original brain storm optimization (BSO) algorithm, was proposed to solve the problem of RFID network planning (RNP). GABSO algorithm introduces learning operator and golden sine operator to achieve a balance between exploration and development. Based on GABSO algorithm, an optimization model is established to optimize the position of the reader. The GABSO algorithm was tested on the RFID model and dataset, and was compared with other methods. The GABSO algorithm's tag coverage was increased by 9.62% over the Cuckoo search (CS) algorithm, and 7.70% over BSO. The results show that the GABSO algorithm could be successfully applied to solve the problem of RNP.

Server‐less RFID authentication and searching protocol with enhanced security

This paper focuses on two interesting radio‐frequency identification (RFID) cryptographic protocols: the server‐less RFID authentication protocol that allows readers to authenticate tags without the help of any online backend servers, and the RFID searching protocol in which the verifier explicitly specifies the target tag to be searched and authenticated. These two kinds of RFID protocols play important roles in many RFID applications; however, the existing protocols either had security weaknesses or exhibited poor efficiency. This paper shows the weaknesses, and then proposes our server‐less RFID authentication protocol and RFID searching protocol. The proposed protocols greatly enhance the security using one more hashing. Copyright © 2011 John Wiley & Sons, Ltd.
