Ultralightweight Cryptography for passive RFID systems
RFID (Radio Frequency Identification) is one of the most growing technologies among the pervasive systems. Non line of sight capability makes RFID systems much faster than its other contending systems such as barcodes and magnetic taps etc. But there are some allied security apprehensions with RFID systems. RFID security has been acquired a lot of attention in last few years as evinced by the large number of publications (over 3000). In this paper, a brief survey of eminent ultralightweight authentication protocols has been presented & then a four-layer security model, which comprises of various passive and active attacks, has been proposed. Finally, Cryptanalysis of these protocols has also been performed under the implications of the proposed security model
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
Pitfalls in Ultralightweight RFID Authentication Protocol
Radio frequency identification (RFID) is one of the most promising identification schemes in the field of pervasive systems. Non-line of sight capability makes RFID systems more protuberant than its contended systems. Since the RFID systems incorporate wireless medium, so there are some allied security threats and apprehensions from malicious adversaries. In order to make the system reliable and secure, numerous researchers have proposed ultralightweight mutual authentication protocols; which involve only simple bitwise logical operations (AND, XOR & OR etc.) to provide security. In this paper, we have analyzed the security vulnerabilities of state of the art ultralightweight RFID authentication protocol: RAPP. We have proposed three attacks (two DoS and one Desynchronization) in RAPP protocol and challenged its security claims. Â Moreover, we have also highlighted some common pitfalls in ultralightweight authentication protocol designs. This will help as a sanity check, improve and longevity of ultralightweight authentication protocol designs
Cryptanalysis of a new ultralightweight RFID authentication protocol—SASI
Since RFID tags are ubiquitous and at times even oblivious to the
human user, all modern RFID protocols are designed to resist tracking so that the
location privacy of the human RFID user is not violated. Another design criterion
for RFIDs is the low computational effort required for tags, in view that most tags
are passive devices that derive power from an RFID reader’s signals. Along this
vein, a class of ultralightweight RFID authentication protocols has been designed,
which uses only the most basic bitwise and arithmetic operations like exclusive-
OR, OR, addition, rotation, and so forth. In this paper, we analyze the security of
the SASI protocol, a recently proposed ultralightweight RFID protocol with better
claimed security than earlier protocols. We show that SASI does not achieve
resistance to tracking, which is one of its design objectives
MUMAP: Modified Ultralightweight Mutual Authentication protocol for RFID enabled IoT networks
Flawed authentication protocols led to the need for a secured protocol for radio frequency identification (RFID) techniques. In this paper, an authentication protocol named Modified ultralightweight mutual authentication protocol (MUMAP) has been proposed and cryptanalysed by Juel-Weis challenge. The proposed protocol aimed to reduce memory requirements in the authentication process for low-cost RFID tags with limited resources. Lightweight operations like XOR and Left Rotation, are used to circumvent the flaws made in the other protocols. The proposed protocol has three-phase of authentication. Security analysis of the proposed protocol proves its resistivity against attacks like desynchronization, disclosure, tracking, and replay attack. On the other hand, performance analysis indicates that it is an effective protocol to use in low-cost RFID tags. Juel-Weis challenge verifies the proposed protocol where it shows insusceptibility against modular operations
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
