Advances in wireless and mobile communication technologies have enabled the development of various RFID-based systems and applications in addition to the extension of the tag reading range of mobile readers. Thus, it has become commonplace that multiple readers concurrently attempt to read tags within ranges of the readers. However, this concurrent access among multiple mobile readers brings ab...

Frame slotted ALOHA (FSA) protocol is a classic tag anti-collision protocol. Similar to most existing anti-collision protocols, The FSA initially aims at tag identification of static scenarios, that is, all tags keep still during the tag identification process. However, in many real scenarios, tags generally move along a fixed path in the reader coverage area, that is, tags stay the coverage ar...

RFID (Radio Frequency IDentification) system has been widely used in our life, such as transport systems, passports, automotive, animal tracking, human implants, library, and so on. However, the RFID authentication protocols between RF (Radio Frequency) tags and the RF readers have been bring about various privacy problems that anonymity of the tags, tracking, eavesdropping, and so on. Many res...

Many container terminals all over the world strive to be mega-hub port through improving efficiency of terminal operation with high technology. Not only operating equipments in container terminal, but also container terminal gates are introducing state-of-the-art technologies in order to develop an effective gate system. This study focuses on an automation of identification task at gate. We dev...

Recently, Radio frequency identification (RFID) has been an important and ubiquitous infrastructure technology for smart work system. As RFID tags are affixed to all items, they may be used to support various useful services. Security mechanisms for RFID systems, such as authentication and encryption, are therefore of utmost importance. However, there are many risks involved, for example user p...
