Fully Integrated Passive UHF RFID Tag for Hash-Based ...

Passive radio-frequency identification (RFID) tag has been used in many applications. While the RFID market is expected to grow, concerns about security and privacy of the RFID tag should be overcome for the future use. To overcome these issues, privacy-preserving authentication protocols based on cryptographic algorithms have been designed. However, to the best of our knowledge, evaluation of the whole tag, which includes an antenna,...

Differential Rcs of Rfid Tag - Semantic Scholar

The vector differential RCS of an RFID tag as seen by the reader is analysed and, for the first time, compared with experimental results in UHF band. Introduction: Radio frequency identification (RFID) can be traced back to the late 1940's work on using RF modulated backscatter for communications [1]. Fig. 1 illustrates the operation of a modern passive RFID system which includes an RFID reader and an RFID tag, composed of an antenna and an integrated circuit chip. The reader signal alternates between a continuous wave (CW) and modulated transmissions. The tag sends data during...

Abstract

--A new UHF RFID tag antenna used on the surface of a metallic object is proposed in this paper. In practical RFID applications, metals appear in many occasions. However, the UHF band is very sensitive to metal. When the tag antenna is near a metal, its impedance matching, radiation efficiency and directivity change...

Abstract

Radio frequency identification (RFID) is a promising technology for automated non-line-of-sight object identification. However, factors such as object occlusions, metal/liquid opaqueness, environmental conditions, and radio noise degrade the overall availability, reliability, and dependability of RFID systems. We show that simply increasing the number of readers does not adequately address these issues. Instead, we...

Abstract

--RFID has been well established as an effective technology for track and trace applications. In this paper, we go beyond the ID in RFID, and discuss the potential for RFID tags to be used as low cost sensors by mapping a change in some physical parameter of interest to a controlled change in RFID tag antenna electrical properties. We will also show that it is possible to design the tag antenna...

Abstract

Radio-frequency identification (RFID) technology is the enabler for applications like the future internet of things (IoT), where security plays an important role. When integrating security to RFID tags, not only the cryptographic algorithms need to be secure but also their implementation. In this work we present differential power analysis (DPA) and differential electromagnetic analysis (DEMA) attacks on a securityenabled RFID tag. The attacks are conducted on both an...

Abstract

Process mining facilitates the analysis of business processes by extracting a process model from event logs. Most mining algorithms perform well on single-system event logs that explicitly refer to a process instance or case. However, in many operational environments such case identifiers are not...
