RFID 시스템에서 태그와 리더 사이의 통신은 Radio Frequency를 이용해서 이루어짐으로 공격자에 의해 도청될 수 있으며, 태그의 정보가 노출되면 사용자의 프라이버시 침해 문제를 가져올 수 있다. RFID 태그의 프라이버시를 보호하기 위해 제안된 대부분의 기존 방식들은 태그의 ID를 식별하기 위해 모든 태그에 대한 정보를 가지고 식별 과정을 수행해야 하는 비효율성을 가지고 있다. 본 논문에서는 태그의 출력을 매번 다르게 변화시켜, 태그에 대한 위치 추적을 불가능하게 하고, 3번의 지수연산만으로 해당 태그를 식별할 수 있는 RFID 가변 정보화 방식을 제안한다.

This paper proposes unforgeable RFID variable n scheme with efficient identification. The existing schemes on privacy protection are in efficient because a server should execute identification process with all Tag ID's Information in order to identify a certain Tag. Moreover these schemes have the serious problem that an attacker can forge special tags if he can know tag's secret information stored in the server's database. Our scheme Is required only 2 times exponent computation to identify a tag. The proposed scheme is also secure against leakage of tags information stored in a database, because an attacker cannot forge special tag even if he knows secret information of the server(database).

최근 유비쿼터스 주요 이슈로 부각되는 Atuo ID나 유비쿼터스 ID(Ubiquitous ID)은 RFID(Radio Frefuency Identification) 태그(Tag)를 사용한 차세대 ID 체계이다. 이들 식별 체계는 해당 물품에 부착된 태그 정보를 RFID 리더(Reader)가 판독하여 이를 바탕으로 식별 작업을 수행함으로써 짧은 시간에 많은 물류 식별 처리가 가능할 수 있는 메커니즘을 가지고 있다. 하지만 리더가 수많은 태그 정보를 한꺼번에 모두 받아드림으로써 발생하는 여러 가지 오류가 발생할 수 있는데, 이를 충돌 문제(collision problem)이라 한다 본 논문은 충돌 문제들의 형태를 분석하고, 이를 개선할 수 있는 방안에 대해 모색, 제안하고자 한다.

Identification and authentication of the security requirements of the application area. Individual ID for uniquely be identified. Standard length of the password is limited and should be applied in combination. And must be changed periodically. ID/PW authentication scheme non-reinforced must be provided. The authentication process is defined in the security requirements should be satisfied.

Current address-based Internet has started to expose the number of limitations, with the growth of the Internet. Most of the problems have been solved by adding new features to the Internet or some modification of existing features but some problems can not be solved because it is believed that the structural limitations of the Internet. Overcoming to fundamentally the limitations of the Internet, ID-based Future Internet research is under active research going on in the competitive atmosphere of the United States and Europe. However, most studies have been promoted in a specific field is concentrated in a limited area. For the future Internet, there is a need to derive the requirements to overcome the limitation and accommodate the features and advantages of the existing studies. This paper compares and analyzes the characteristics and advantages and disadvantages for the ID-based Future Internet Research, and describes the requirements to have the ID-based Future Internet.

Since research articles aren't be fixed in particular system, author name of articles have been handled not by authority control but by unique identifier. While unique identifier has a tendency that moves toward open-transparent global link system, lately ORCID has been initiated. ORCID is not only link diverse existing ID system as a partner, for example, publisher's ID systems, university's research assessment systems, manuscript tracking systems but also let researchers self-claim by themselves to identify their own articles. Though, since ORCID run based on overseas' publications, it is not appropriate to adapt ORCID shortly to Korean researcher's identification. So this study suggests the direction of domestic researcher's identification system by applying ORCID.

The code division multiple access(CDMA) system capacity is limited by the amount of interference of the system. To reduce the unnecessary interference, this paper proposes optimized cell identification codes for site selection diversity transmission(SSDT) power control in wideband code division multiple access system of third generation partnership project(3GPP). The main objective of SSDT power control is to transmit on the downlink from the primary cell, and thus reducing the interference caused by the multiple transmission. In order to select a primary cell, each cell is assigned a temporary identification(ID) and user equipment(UE) periodically informs a primary cell ID to the connecting cells during soft handover. The non-primary cells selected by UE do not transmit the dedicated physical data channel(DPDCH) to reduce the interference. A major issue with the SSDT technology is the impact of uplink symbol errors on its performance. These errors can corrupt the primary ID code and this may lead to wrong decoding in the base station receivers. The proposed SSDT cell ID codes are designed to minimize the problem and to be easily decoded using simple fast Hadamard transformation(FHT) decoder.

Recently, Construction business is changing from on the ground to underground space because of deficit of developing space, creation of green space and of incremental of land compensation expenses. Meanwhile, 3D Topographic, Marine and Cadastral maps need to have Spatial Interrelation. Also, understanding of the information is also needed. Spatial information object registration system is impossible to contact and understanding intelligence mutually because the former one is managed as automatic ID system. Therefore, 3D Object information ID System of underground space is managed based on Object Identifier. Construction of Spatial information integration ID System is required and it will offer Division Code (Ground, Index, Underground) and depth information. We are defined and classified Under Spatial Information in this paper. Moreover, we developed the integration ID System based on UFID for cadastral information Construction. We supposed underground spatial information DB Construction and a developed the way of exploiting 3D cadastral information system through the study. The research result will be the base data of Standard ID system, DB Construction and system Development of National spatial data which is considered together with spatial interrelation.

Single frequency network (SFN) design based on the Advanced Television Systems Committee (ATSC) specification, a terrestrial digital television (DTV) system, normally causes a interference problem, among signals from multiple transmitters or repeaters. To solve this, the ATSC recommended practice (RP) introduces a transmitter identification (TxID) signal embedded in a signal from each transmitter or repeater. A TxID signal analyzer is then used to detect the TxID signal, and following the analysis results, a SFN design can be adjusted. This paper discusses the generation and usages of Kasami sequence, is used the TxID signal. The configuration of the TxID signal analyzer to efficiently detect TxID signal is proposed and the results of theoretical performance analysis are provided. Moreover, computer simulation and laboratory test results are provided to evaluate the performance of TxID signal analyzer and the theoretical performance analysis.
