In this paper we present new constraints to EPCglobal Class 1 Generation 2 (EPCC1 G2) standard which if they have been considered in the design of EPC-C1 G2 complaint authentication protocols, lead to prevent predecessor’s protocols’ weaknesses and also present the secure ones. Also in this paper as an example, we use Pang et al. EPC-C1 G2-friendly protocol which has been recently proposed, to ...

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...

Recently, due to widespread use of Radio Frequency IDentification (RFID) systems in personal applications, security and privacy of these systems have got more attention. In order to provide security and privacy of RFID users, different authentication protocols have been proposed. In 2014, Mohammadi et al. proposed an improved authentication protocol for RFID systems. They claimed that their pro...

Security and privacy in RFID systems is an important and active research area. A number of challenges arise due to the extremely limited computational, storage and communication abilities of a typical RFID tag. This work describes two families of simple, inexpensive, and untraceable identification protocols for RFID tags. The proposed protocols involve minimal interaction between a tag and a re...

Mutual authentication mechanisms can be used in RFID systems to preserve the confidentiality of the RFID tags. Hiding the unique IDs of the tags is critical to prevent unauthorized tag tracking. In this paper, we analyze two mutual authentication protocols called MAP and EMAP, recently proposed by Peris-Lopez et. al. We show that a passive adversary eavesdropping on the open wireless medium, ca...

Several threats in RFID systems are obstacles to intermingle this technology into human lives. On the other hand ensuring flexible privacy mechanism has been an enormous challenge due to extremely inadequate computational storage of typical RFID tags. So in order to relieve tags from responsibility, privacy protection and security assurance was guaranteed by central server. In this paper, we de...

RFID has been more and more attention and application by people, but the existence of security and privacy problems worthy of attention is concern. The certification process analysis of several typical security protocols is based on existing RFID authentication protocol. It proposed an improved bidirectional authentication algorithm. The use of one-way HASH function can solve the security probl...

This thesis includes my research on efficient cryptographic protocols, sensor network key management, and radio frequency identification (RFID) authentication protocols. Key exchange, identification, and public key encryption are among the fundamental protocols studied in cryptography. There are two important requirements for these protocols: efficiency and security. Efficiency is evaluated usi...

recently, baghery et al. [1, 2] presented some attacks on two rfid protocols, namely yoon and jung et al. protocols, and proposed the improved version of them. however, in this note, we show that the improved version of the jung et al. protocol suffers from desynchronization attack and the improved version of the yoon's protocol suffers from secret disclosure attack. the success probabilit...

This document consists of a description of attack methodologies and a collection of detailed attacks upon RFID protocols. It is meant to serve as a quick and easy reference and it will be updated as new attacks are found. Currently the only attacks on protocols shown in full detail are the authors’ original attacks with references to similar attacks on other protocols. The main security propert...
