as a response to a growing interest in rfid systems such as internet of things technology along with satisfying the security of these networks, proposing secure authentication protocols are indispensable part of the system design. hence, authentication protocols to increase security and privacy in rfid applications have gained much attention in the literature. in this study, security and privac...

Group signatures were introduced by Chaum and Van Heyst [12], and many security requirements for group signatures have been proposed. Bellare, Micciancio, and Warinschi [4] showed that satisfying full-anonymity and full-traceability is sufficient, in the sence that all the above-mentioned requirements are implied by them. Wilson and Menezes [5] introduced a considerable attack against standard ...

Low cost Radio Frequency IDentification (RFID) tags are increasingly being deployed in various practical applications these days. Security analysis of the way these tags are used in an application is a must for successful adoption of the RFID technology. Depending on the requirements of the particular application, security demands on these tags cover some or all of the aspects such as privacy, ...

RFID technology is a system which uses radio frequency to transmit data. Data transmission between Tags and Readers is wireless which can be easily eavesdropped by adversary. Due to security and privacy reasons, various authentication protocols proposed. In this paper, we cryptanalyze two different RFID authentication protocols and it is shown that either of them have some weaknesses. In 2014, ...

Radio Frequency Identification (RFID) applications have spread all over the world and, in order to provide their security and privacy, researchers proposed different kind of protocols. In this paper, we analyzes the privacy of a new protocol, proposed by YuJehn in 2015 which is based on Electronic Product Code Class1 Generation 2 (EPC C1 G2) standard. By applying the Ouafi-Phan privacy model, w...

Radio Frequency Identification (RFID) is a modern communication technology, which provides authentication and identification through a nonphysical contact. Recently, the use of this technology is almost developed in healthcare environments. Although RFID technology can prepare sagacity in systems, privacy and security issues ought to be considered before. Recently, in 2015, Li et al. proposed S...

Remote user authentication is an essential part in electronic commerce to identify legitimate users over the Internet. However, how to protect user privacy in the authentication has become an important issue recently. Therefore, many secure authentication schemes with smart cards have been proposed. In this paper, we will analyze the security weaknesses of two recently proposed authentication s...

Radio frequency identification systems need protocols to provide confidentiality, user privacy, mutual authentication and etc. These protocols should resist active and passive attacks such as forgery, traceability, replay and desynchronization attacks. In this paper we cryptanalysis a hash based RFID mutual authentication protocol which has been recently proposed by Cho et al. More precisely, w...

Tian et al. proposed a novel ultralightweight RFID mutual authentication protocol [4] that has recently been analyzed in [1], [2], [5]. In this letter, we first propose a desynchronization attack that succeeds with probability almost 1, which improves upon the 0.25 given by the attack in [1]. We also show that the bad properties of the proposed permutation function can be exploited to disclose ...
