RFID/USN is important infrastructure of the ubiquitous society. And so, It is various and practical research is attempted. These two base technology have physical characteristic and complement relationship. Like this relationship is applied Following example that is system research which manages warehouse stocks and conditions. First, We adhere RFID Tag at the Pallet of the warehouse and do identification goods. And then, It grasps the environment state information of stocks with sensor module which has Zigbee wireless communication function. From like this process RFID Tag information and jop-control command of sensor node also it is exposed to air. Therefore, We control sensor node in USN/RFID environment through the mobile device. And system design for the security Apply of the process is main purpose of this paper's. We propose the condition and function of the mobile device to the secondary. And We define the relation of the sensor node with RFID to be arranged to a warehouse. Finally, This paper is designed to find a trade-off of the following viewpoints. First, We offer suitable sensor-control information to a actual manager. Second, We offer RFID tag security approach to control the action of the sensor. Third, It increases the survivability of sensor node form.

In order to build up the ubiquitous computer environment, there are many researches on automatic identification, sensor networks, and home networks etc. EPCIS (EPC Information Services), which is proposed by EPCglobal, is a standard on the repository managing tag data that is needed to develop RFID application system. In this paper, the EPCIS repository is designed and implemented. It is able to search the object dependent upon general object recognition and environment information variation. And sensor data, which is also massive data and is changed with position, is integrated into RFID data in the system. By doing so, it is possible to do the convergence managements of object recognition with variations of USN (Ubiquitous Sensor Network) environment.

This paper presents the development of RFID educational system based on 900MHz air interface between the reader and the active tag. The software of reader and the active tag is developed on embedded environment, and the software of PC controlling the reader is based on window OS operated as the server. The ATmega128 VLSI chip is used for the processor of the reader and the active tag. As the development environment, AVR compiler is used for the reader and the active tag of which the programming language is C. The visual C++language of the visual studio on the PC activated as the server is used for development language. Main functions of this system are to control tag containing EPC global Data by PC through the reader, to obtain information of tag through the internet and to read/write data on tag memory. Software design of 900MHz RFID/USN educational system is done on the basis of these functions.

As the era of ubiquitous has come, it is able to have more convenient and efficient operation system since many efforts have devoted to developing an appropriate operation system in the ubiquitous environment and applying RFID/USN technology to various parts in the industry. Also, the port logistics area has considered RFID/USN to develop more efficient port logistics environment and improve their efficiency. Therefore, this study investigates current trends of RFID technology and application cases in the port logistics area since RFID stands in the important position of changes of maritime port environment. This study tries to find possible areas for applying RFID technology and analyze expected effects when RFID is adopted those areas. Lastly, the priority level among the possible RFID application fields in the container terminal has been evaluated by experts' survey.

유비쿼터스 시대에서는 하나의 단말기를 활용해 언제 어디서나 끊김 없이 다양한 멀티미디어 서비스를 사용할 수 있게 될 것이며, 이는 광대역통합망(BcN)을 중심으로 RFID/USN이 All-IP망으로 통합되는 네트워크 환경을 통해서 실현될 것이다. 정부는 u-Korea 건설이라는 시대적 요구사항을 적극 수용한 유비쿼터스 코리아(u-Korea) 전략을 수립하였다. 이러한 추진전략이 성공하기 위해선 가장 밑바탕에 있는 해킹 바이러스로 인한 폐해 등의 현재 지식기반사회에서의 각종 정보화 역기능을 해소해야 한다. 따라서, 본 고에서는 유비쿼터스 관련 기술인 RFID와 바이오 보안 기술을 융합한 보안을 중심으로 이를 해결하기 위한 방법을 연구하였다.

The essential factor of ubiquitous is security technology to properly prepare making possible network access, economic and convenient information exchange. This paper proposes an authentication protocol for RFID as one technology to realize such an ubiquitous. The proposed protocol used only the EXOR and the hash function operations reduces operations at RFID tag, which improves stability compared to existing protocols.

RFID/USN은 여러 산업분야 및 실생활에 많은 활용이 기대되는 분야이다. 그 중 RFID는 교통카드 및 자산관리, 물류관리, 출입통제 등 여러 분야에서 적용되고 있다. 최근 군부대에서까지 RFID 시스템을 활용한 'u국방' 체제 확립에도 그 적용이 확산되고 있다. 그러나 RFID 시스템의 경우, Tag의 규격 및 프로토콜에 따라 Reader의 전반적인 사양이 달라지는 문제가 발생하고 있다. 본 연구에서는 이러한 문제에 착안하여 ATmel사의 읽기/쓰기가 가능한 IDIC인 T5557을 활용하여 RFID 시스템을 구현하고, 임의로 설정한 Tag ID 정보를 이용하여 터미널 프로그램을 통해 수신 가능함을 보였다.
