The current excessive limitations to mobile RFID tags and readers make it impossible to apply present codes and protocols. The technology for information and privacy protection should be developed in terms of general interconnection among elements and their characteristics of mobile RFID in order to such technology that meets the RFID circumstances. In this paper, transplanting and extending security library for protecting mobile RFID information in secure mobile RFID terminal S/W platform system to support security application on the path of all data from RFID reader to application server.

Nowadays there are many studies and there's huge development about USN/RFID which have great developmental potential to many kinds of applications. More and more real time application apply USN/RFID technology to identify data collect and locate objects. Wide deployment of USN/RFID will generate an unprecedented volume of primitive data in a short time. Duplication and redundancy of primitive data will affect real time performance of application. Thus, security applications must filter primitive data and correlate them for complex pattern detection and transform them to events that provide meaningful, actionable information to end application. In this paper, we design a ECA Rule system for security monitoring of exhibition. This system will process USN/RFID primitive data and event and perform data transformation. It's had applied each now in exhibition hall through this study and efficient data transmission and management forecast that is possible.

In this study, we propose an RFID based container terminal operation process. Field tests are conducted for 900 MHz (truck identification) tag and 433 MHz RFID (container identification/e-seal) tag at an Incheon container terminal to verify possibility of applying RFID in the container terminal gate. To evaluate effect of applying RFID in the container terminal operation, simulation models for current and RFID based container terminals are developed using ARENA. Simulations are carried out using industrial field data and the result indicates that performance of the container terminal can be prominently improved after RFID application.

Various kinds of studies for building up U-Korea are now underway. Especially, many results of educational application field such as U-Learning and U-Campus applying a USN technique have been founding. There are not, however, enough researches for the student management related to elementary, middle and high school. Therefore, this paper will suggest effective application system of student management which is one of the application systems for a user - centered environment using RFID and NEIS system in Ubiquitous. This system is enable to make it efficiently managed and transmitted students' data about their location and the details of their counsel(career, health and so on).

We proposed a goods load simulator for optimum RFID distribution, which includes experiment process modeling guidelines for stable RFID scan rate, efficient cost-reduction of RFID application or even speedy management of RFID field. We show verification of this simulator using field test of distribution, and the proposed simulator has better performance than the classic method, and demonstrate the proposed is efficient method of draw up guidelines on RFID distribution.

The concept of Smart-Homes is becoming more and more popular. It is anticipated that Radio Frequency IDentification (RFID) technology will play a major role in such environments. We can find many previously proposed schemes that focus solely on: authentication between the RFID tags and readers, and user privacy protection from malicious readers. There has also been much talk of a very popular RFID application: a refrigerator/bookshelf that can scan and list out the details of its items on its display screen. Realizing such an application is not as straight forward as it seems to be, especially in securely deploying such RFID-based applications in a smart home environment. Therefore this paper describes some of the RFID-based applications that are applicable to smart home environments. We then identify their related privacy and security threats and security requirements and also propose a secure approach, where RFID-tagged consumer items, RFID-reader enabled appliances (e.g., refrigerators), and RFID-based applications would securely interact among one another. At the moment our approach is just a conceptual idea, but it sheds light on very important security issues related to RFID-based applications that are beneficial for consumers.

Nowadays, to realize ubiquitous computing environment, many research activities have been going on within various kinds of research domains including automatic identification sensor network, home network, telematics and so on. Especially, RFID middleware that supports the aggregation of RFID tag data, control and management, and the integration with legacy systems has recently gained a lot of attention. Meanwhile, EPCglobal defined an ALE(Application Level Events) standard specification, which exists between RFID readers and applications, and substitutes the previous systems called Savant. In the specification internal structures and implementation technologies of ALE are not mentioned and only external interfaces are defined. This approach easies the verification of standard compliance and inter-operability of the layer. In this paper, we present the design of ALE-compliant RFID middleware systems that process RFID tag data efficiently.

Recently, RFID technology has attracted considerable attention in many industry fields. The RFID environment requires a standard architecture for the smooth exchange of data between heterogeneous networks. The architecture should offer an efficient standard environment, such as a communication environment based on Web Services, PKI or Kerberos-based security, and abstract business processes which could be used in the diverse domains. Therefore, in this paper, we propose an Enterprise Application Framework (EAF) which includes a standard communication protocol, security functions, and abstract level business processes. The suggested architecture is expected to provide a more secure and flexible security management in the dynamic RFID application environments, and is expected to provide an abstract business event for the development of business processes which could apply RFID technology to the existing systems.

최근 다양하고 복잡한 물류 환경을 지원하기위해 다양한 비즈니스 솔루션이 생겨났다. 기업에서는 이러한 비즈니스 솔루션을 이용하고 있지만, 더 나은 물류 시스템 구축을 위해 RFID 시스템과의 통합에 많은 관심을 가지게 되었다. 이러한 RFID기반의 효율적인 엔터프라이즈 애플리케이션을 위해서는 다양한 비즈니스 요구를 수용할 수 있는 개발환경이 제공되어야 한다. 또한 성능 향상 및 확장성, 그리고 새로운 애플리케이션으로의 전환 및 레거시 시스템과의 연동을 고려한 표준 환경의 지원이 필요하다. 본 논문에서는 RFID 기반의 엔터프라이즈 애플리케이션 개발 환경을 위한 효율적인 Enterprise Application Framework(EAF)를 제안한다. EAF는 EPCglobal Network, 웹 서비스, XML 등의 표준 환경을 기반으로 애플리케이션 개발에 표준을 제공한다. 또한 여러 도메인의 물류 시스템을 고려하여 효율적으로 RFID관련 비즈니스 프로세스를 개발할 수 있는 기능을 제공한다.

현재 RFID 네트워크의 구조적 기준이 되는 EPC 네트워크는 HTTP/SOAP 통신 프로토콜과 HTML/XML을 이용하여 서비스를 제공한다. 반면 모바일 RFID 네트워크에서는 휴대 단말기의 특성에 따라 WAP방식 및 HTTP방식으로 서비스가 제공되고 있지만 단말기의 제약으로 인해 다양한 서비스 이용이 불가능 하다. 이와 같은 차이점으로 인해, 같은 RFID 네트워크 임에도 달구하고 논리적으로 두 개의 네트워크로 구분되며 서비스의 상호연동이 불가능 하다. 본 논문에서는 기존의 EPC 네트워크 구성을 따르며 모바일 RFID 네트워크의 구조변경없이 두 네트워크 간의 서비스 연동을 위한 구성 요소인 Application Server(AS)와 Mobile RFID Application Level Gateway(mRFID-ALG)를 제시한다.
