Cryptanalysis of two mutual authentication protocols for low-cost RFID
Radio Frequency Identification (RFID) is appearing as a favorite technology
for automated identification, which can be widely applied to many applications
such as e-passport, supply chain management and ticketing. However, researchers
have found many security and privacy problems along RFID technology. In recent
years, many researchers are interested in RFID authentication protocols and
their security flaws. In this paper, we analyze two of the newest RFID
authentication protocols which proposed by Fu et al. and Li et al. from several
security viewpoints. We present different attacks such as desynchronization
attack and privacy analysis over these protocols.Comment: 17 pages, 2 figures, 1 table, International Journal of Distributed

On the Privacy of Two Tag Ownership Transfer Protocols for RFIDs
In this paper, the privacy of two recent RFID tag ownership transfer
protocols are investigated against the tag owners as adversaries. The first
protocol called ROTIV is a scheme which provides a privacy-preserving ownership
transfer by using an HMAC-based authentication with public key encryption.
However, our passive attack on this protocol shows that any legitimate owner
which has been the owner of a specific tag is able to trace it either in the
past or in the future. Tracing the tag is also possible via an active attack
for any adversary who is able to tamper the tag and extract its information.
The second protocol called, Chen et al.'s protocol, is an ownership transfer
protocol for passive RFID tags which conforms EPC Class1 Generation2 standard.
Our attack on this protocol shows that the previous owners of a particular tag
are able to trace it in future. Furthermore, they are able even to obtain the
tag's secret information at any time in the future which makes them capable of
impersonating the tag
Survey on Lightweight Primitives and Protocols for RFID in Wireless Sensor Networks
The use of radio frequency identification (RFID) technologies is becoming widespread in all kind of wireless network-based applications. As expected, applications based on sensor networks, ad-hoc or mobile ad hoc networks (MANETs) can be highly benefited from the adoption of RFID solutions. There is a strong need to employ lightweight cryptographic primitives for many security applications because of the tight cost and constrained resource requirement of sensor based networks. This paper mainly focuses on the security analysis of lightweight protocols and algorithms proposed for the security of RFID systems. A large number of research solutions have been proposed to implement lightweight cryptographic primitives and protocols in sensor and RFID integration based resource constraint networks. In this work, an overview of the currently discussed lightweight primitives and their attributes has been done. These primitives and protocols have been compared based on gate equivalents (GEs), power, technology, strengths, weaknesses and attacks. Further, an integration of primitives and protocols is compared with the possibilities of their applications in practical scenarios
