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...

One of the interesting types of RFID application is RFID searching which aims to hear a specific RFID tag from a large group of tags, i.e. ability of detecting whether a target RFID tag is nearby. Very recently, a lightweight protocol using error-correcting codes has been proposed by Chen et al. to provide a solution to needs in this field. The authors give a detailed analysis of their protocol...

We propose to extend basic RFID usage by storing semantically annotated data within RFID tags memory, so that objects may actually “describe themselves” in a variety of scenarios. In particular here we exploit our approach to carry out an advanced discovery process using annotations stored in RFIDs. A –fully backward compatible– modification to the original RFID data exchange protocol is presen...

Radio Frequency Identification (RFID) system is a wireless automatic identification using low-cost RFID tags. Promotion of privacy and security in systems has been considered essential due to their usage everyday life. In 2012, Guo-Rui Li et al. Proposed new Efficient Mutual Authentication Protocol for passive (EMAP), that providing confidentiality, un-traceability, efficiency. addition proving the ...

RFID technology raises many privacy concerns among which the potential tracking of an RFID tag bearer and the possibility of collecting information about him. As RFID tags may often change hands, it is also necessary to guarantee the privacy of a new tag owner. In this paper, we introduce a new protocol based on pseudonyms that solves these privacy issues while enabling tag identification witho...

RFID is a key technology that can be used to create the pervasive society. The tag is an important part of the RFID system and most popular tags are some low-cost passive tags. These tags have limited computing and storing resources, and no more attentions are paid to their security and privacy. So the application of these tags is not secure. Lightweight authentication protocols are considered ...

In recent years, due to the proliferation of radio frequency identification (RFID) technology in everyday life, especially in critical domains such as health care and transportation systems, significant efforts have been made to enhance the dependability of this technology. From these efforts have emerged specific techniques and several middleware solutions to handle the large amount of the RFI...

In this paper, we introduce a new class of PRSGs, called partitioned pseudorandom sequence generators(PPRSGs), and propose an RFID authentication protocol using a PPRSG, called S-protocol. Since most existing stream ciphers can be regarded as secure PPRSGs, and stream ciphers outperform other types of symmetric key primitives such as block ciphers and hash functions in terms of power, performan...

The collision of ID signals from a large number of colocated passive RFID tags is a serious problem; to realize a practical RFID systems we need an effective anti-collision algorithm. This letter presents an adaptive algorithm to minimize the total time slots and the number of rounds required for identifying the tags within the RFID reader’s interrogation zone. The proposed algorithm is based o...

As for security of RFID network, this paper has proposed a safe, effective and scalable RFID Authentication Protocol (CRFID) with cloud database as server. Firstly, the tree-structure management tag is used to achieve privacy protection, and the time complexity of RFID system in search of cloud database is reduced from O (N) to O (logN); then, the size of each subkey in keys route of the RFID t...
