유비쿼터스 사회를 만들기 위한 핵심 기술인 RFID는 시간과 공간을 초월하여 우리에게 정보를 제공해 줄 것으로 기대되고 있지만, RFID 시스템이 가지고 있는 특성으로 인하여 프라이버시를 침해할 수 있다는 심각한 문제를 안고 있다. 이를 해결하기 위한 방법으로 다양한 연구가 진행되어 왔지만 기존의 연구들은 보안상 문제점과 태그 및 백 엔드 데이터베이스의 과도한 처리능력을 요구하고 있다. 그러나 본 논문에서 제안하는 프로토콜은 해쉬함수와 XOR연산, 키 교환을 이용하여 스푸핑이나, 재전송 공격으로부터 안전 하면서도, 백 엔드 데이터베이스 안에서의 비교연산 횟수를 줄일 수 있는 경량화된 프로토콜을 제안한다.

Cyber lectures have been popular with students as they are more accessible. In this thesis we also created a personal identification confirmation system with RFID as it is quite difficult to confirm who is taking a lecture. In the process of developing the confirmation system, an algorithm enabling real-time identification confirmation, as well as interactive virtual questioning system, was also developed. After the computer simulation test we proved the duplex on-line lecturing system is more effective than the current one-way cyber lecturing system which does not take into consideration students with less/no degree of understanding.

Home network is a network composed of devices in home and is being expanded by evolving devices. Also, The number of digital contents in home network has been increasing steadily. But it is difficult to continually protect the rights of digital contents due to lack of interoperability among contents devices. Besides, a license has to be re-issued by DRM sever for contents transfer between devices. Thus, this paper proposes framework which can freely transfer and contents to another device through mutual device authentication and a system that can decrease overload of license management of the DRM sever and that enable device outside home network to use contents through user authentication.

This paper presents a user authentication scheme for healthcare application using wireless sensor networks, where wireless sensors are used for patients monitoring. These medical sensors' sense the patient body data and transmit it to the professionals. Since, the data of an individual are highly vulnerable; it must ensures that patients medical vital signs are secure, and are not exposed to an unauthorized person. In this regards, we propose a user authentication scheme for healthcare application using medical sensor networks. The proposed scheme includes: a novel two-factor user authentication, where the healthcare professionals are authenticated before access the patient's body data; a secure session key is establish between the patient sensor node and the professional at the end of user authentication. Furthermore, the analysis shows that the proposed scheme is safeguard to various practical attacks and achieves efficiency at low computation cost.

In food choice, consumers consider importantly food safely and reliability focusing on a high qualify control. Also they are concerned about sustainable production and consumption considering of area and environment. In this paper, We propose and design the high-quality seafood production support system that is based on international sanitary standard haccp, traceability and eco-fiendly seafood certification for safety and reliability of the seafood production. The system is categorized into five part: aquafarm haccp, environmental control monitoring, traceability, disease prevention and messenger service and seafood price inquiry service. The proposed system utilize diverse ubiquitous-it technologies like usn, network cctv, mobile device etc.

A secured building where only approved personnel can access is sometimes not secured because of the lack of recognition of security. Unapproved personnel enter and access freely to the internal system of the building, and this makes security risks. In order to deal with these problems, the existing entrance-control system had developed by using the RFID card certification and the infrared sensor to measure distance. However, it is difficult for the system to guarantee security due to the weakness of each method. Therefore, this study aimed at providing a new method of guaranteeing security by comparing the double entrance-control system and the existing entrance-control system.

The Food is very important in our life, And the agricultural products are one of the most important food materials. For buying it, it's hard for the consumer to trust the agricultural products. That this reason, why they can't easily get the product information about agricultural productions. If you can get it, It is only mark of information about The country of production, They can not get reliable informations such as Producers, productions, residual pesticides, and soil conditions, etc. Accordingly, When consumers buy these agricultural productions, They want to provide reliable information. In this paper, using an RFID(Radio-Frequency IDentification) reader who reads RFID TAG attached to products. Then, Acquired Certification Number sent to a web server. To get the Production informations and Safety Inspection Information. The way that consumers can trust the Agricultural Products. These Traceability systems were implemented.

This paper implements the standby power control system composed of a master device and slave devices. The standby power is managed by cutting power supply after controlling the relay of a slave device based on the authentication of master device's RFID card. RFID interface and wireless communication module are embedded in a master device, and one master device is linked with many slave devices in wireless. Each slave device executes the operation needed in power control independently. We implements the function of manual power on/off system in a slave device, and the function of user ID enrollment by switch manipulation in a master device. Also this system can communicate bidirectionally in wireless and runs on TinyOS. The result of experiment shows that the user authentication is executed in a master device and this authenticated information is transmitted to a slave device in wireless, and standby power is cutted by controlling the relay of a slave device. Installing this system in a building or an office, we can expect energy saving.
