Lightweight Mutual Authentication Protocol for Low Cost RFID Tags
Radio Frequency Identification (RFID) technology one of the most promising
technologies in the field of ubiquitous computing. Indeed, RFID technology may
well replace barcode technology. Although it offers many advantages over other
identification systems, there are also associated security risks that are not
easy to be addressed. When designing a real lightweight authentication protocol
for low cost RFID tags, a number of challenges arise due to the extremely
limited computational, storage and communication abilities of Low-cost RFID
tags. This paper proposes a real mutual authentication protocol for low cost
RFID tags. The proposed protocol prevents passive attacks as active attacks are
discounted when designing a protocol to meet the requirements of low cost RFID
tags. However the implementation of the protocol meets the limited abilities of
low cost RFID tags.Comment: 11 Pages, IJNS
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

Enhancing the security of RCIA ultra-lightweight authentication protocol by using Random Number Generator (RNG) technique
This study is an attempt to enhance the security of Robust Confidentiality, Integrity, and Authentication (RCIA) ultra-lightweight authentication protocols.In the RCIA protocol, IDs value is sent between reader and tag as a constant
value.This makes RCIA susceptible to traceability attack which lead to the privacy issue. In order to overcome this problem, Random Number Generator (RNG) technique based on Bitwise operations has been used in the tag side.The idea of this
technique is to change the IDs of a tag on every query session so that it will not stay as a constant value.The implementation of Enhanced RCIA has been conducted by using a simulation.The
simulation provided the ability to show that the operations of RCIA protocol as to compare with the enhanced RCIA.The outcome shows that the enhanced RCIA outperforms existing one in terms of privacy
Enhancing the security of RCIA ultra-lightweight authentication protocol by using random number generator (RNG) technique
With the growing demand for low-cost Radio Frequency Identification (RFID) system, there is a necessity to design RFID ultra-lightweight authentication protocols to be compatible with the system and also resistant against possible attacks. However, the existing
ultra-lightweight authentication protocols are susceptible to wide range of attacks. This study is an attempt to enhance the security of Robust Confidentiality, Integrity, and Authentication (RCIA) ultra-lightweight authentication protocols especially with regard to privacy issue. In the RCIA protocol, IDs value is sent between reader and tag as a constant value. The constant value will enable attacker to trace the location of the tag which violates the privacy users. In order to enhance the security of RCIA protocol, Random Number Generator (RNG) technique has been used. This
technique relies on generating random numbers in the tag side, based on Bitwise operations. The idea of this technique is to change the IDs of a tag on every query session so that it will not stay as a constant value. The implementation of Enhanced RCIA has been conducted by using a simulation. The simulation provided the ability to show that the operations of RCIA protocol as to compare with the enhanced RCIA. The outcome shows that the enhanced RCIA outperforms existing one in terms of privacy
