The emerging ubiquitous computing is changing the current computing paradigm, and it lets the ubiquitous RFID applications consistently and independently utilize the sensed information from the intelligent and powerful tags which are in a variety of applications fields. One of the most important issues is how to support the semantic consistency between data from various tags in different RFID applications...
Radio frequency identification (RFID) has come under the spotlight as technology supporting ubiquitous society. But now, we face several security problems and challenges in RFID systems. Recent papers have reported that RFID systems have to achieve the following requirements: (1) indistinguishability; (2) forward security; (3) replay attack; (4) tag killing; and (5) ownership transfer. We have to...
The radio frequency identification (RFID) is an automatic identification system, relying on storing and remotely retrieving data about objects we want to manage using devices called RFID tag. Even though RFID system is widely used for industrial and individual applications, RFID tag has a serious privacy problem, i.e., traceability. To protect the users from tracing and also to support low-cost RFID,...
RFID (radio frequency identification) is a RF based identification system, where RF reader reads (and writes) data from each entity (RF tag). Upon request from reader, tags in reader's accessible RF range will respond, and if the number of tags is larger than 2, the reader cannot identify tags (collision). To avoid the collision, there are two previous approaches: ALOHA based and binary tree algorithm...
Previous RFID techniques, cause serious privacy infringements such as excessive information exposure and user's location information tracking due to the wireless characteristics and the limitation of RFID systems. Especially the information security problem of read only tag has been solved by physical method. In this paper, we propose a low-cost mutual authentication protocol which can be adapted...
As the adaptation of RFID technology is increased, the necessity of collaboration and cooperation between different RFID applications domains is getting more important. In this paper, we propose access control and authorization methodology for security of RFID multi-domain. We adopt security assertion markup language (SAML) and extensible access control markup language (XACML) to provide them. The...
