چکیده

radio frequency identification (rfid) applications have spread all over the world. in order to provide their security and privacy, researchers proposed different kinds of protocols. in this paper, we analyze the privacy of a new protocol, proposed by yu-jehn in 2015 which is based on electronic product code class1 generation 2 (epc c1 g2) standard. by applying the ouafi_phan privacy model, we show that the yu-jehn protocol is vulnerable to secret parameter reveal attack, traceability attacks, forward traceability attack and it also does not provide the privacy of rfid users. to enhance the privacy of the analyzed protocol, an improved version of the protocol is proposed which eliminates the existing weaknesses of yu-jehn protocol.

For an EPC-C1 G2 RFID compliant Protocol, CRC with Concatenation : No; PRNG with Concatenation : Yes

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 ...

Cryptanalysis of improved Yeh et al.'s authentication Protocol: An EPC Class-1 Generation-2 standard compliant protocol

EPC class 1 Generation 2(or in short term EPC-C1 G2) is one of the most important standards for RFID passive tags. However, the original protocol known to be insecure. To improve the security of this standard, several protocols have been proposed compliant to this standard. In this paper we analyze the improved Yeh et al. ’s protocol by Yoon which is conforming to EPC-C1 G2 standard and is one ...
