  • Electronic identity (e-ID) card based on smartcard is a representative identity credential for on-line and off-line personal identification. The e-ID card can store the personal identity information securely, so that the information can be accessed fast, automated identity verification and used to determine the cardholder's authorization to access protected resources. Due to such features of an e-ID card, the number of government organizations and corporate enterprises that consider using e-ID card for identity management is increasing. In this paper, we present an authentication framework for access control system using e-ID cards by discussing the threat environment and security requirement against e-ID card. Specifically, to accomplish our purpose, we consider the Personal Identity Verification system as our target model.

  • Most web sites, information systems use the ID/Password technique to identify and authenticate users. But ID/Password technique is vulnerable to security. The user must remember the ID/Password and, the password should include alphabets, numbers, and special characters, not to be predicted easily. User also needs to change your password periodically. In this paper, we propose the user authentication method that the user authentication information stored in the external storage to authenticate a user. If another person knows the ID/Password, he can't log in a system without the external storage. Whenever a user logs in a system, authentication information is generated, and is stored in the external storage. Therefore, the proposed user authentication method is the traditional ID/Password security technique, but it enhances security and, increases user convenience.

  • The connection between devices in Ad-hoc network a network based on trust. Because a temporary device frequently join or leave, the authentication and security technology should be prepared for malicious device of a third-party attacks. The authentication scheme with the existing certification and ID, and the security technology using symmetric key and the public key is used. Therefore, in this paper we proposed two devices not having shared information use to generate each other's authentication ID. The use of authentication ID can establish the mutual trust and, provide security and efficiency for communication uses to generate a symmetric key.

  • This paper is to suggest the security requirements for identification and authentication in analysis step. Firstly, individual ID should be uniquely identified. The second element is to apply the length limitations, combination and periodic changes of passwords. The third should require the more reinforced authentication methods besides ID and passwords and satisfy the defined security elements on authentication process.

  • In a Single Frequency Network (SFN) for Advanced Television Systems Committee (ATSC) terrestrial digital television (DTV) system, the interferences induced by the multiple transmitters and/or repeaters using same frequency are unavoidable. To ease the interference handing in the SFN for ATSC DTV system, transmitter identification (TxID) signal is recommended in the ATSC terrestrial DTV system. The TxID signal is embedded in the ATSC DTV signal and transmitted from each transmitter and repeater within the SFN and in ATSC recommended practice (RP) A/111, Kasami sequence is recommended as the TxID signal. In this paper, we propose an additional data transmission scheme using the TxID signal. In the proposed scheme, the Kasami sequence not only acts as the conventional TxID of the SFN for ATSC terrestrial DTV system but also carriers the additional data bits on its polarity and the code phase.

  • 현재 국내에서 사용되고 있는 신분 인증 시스템은 주민등록번호와 같은 개인 정보를 기반으로 인증을 수행하여, 프라이버시 침해 위협이 존재한다. 그 해결 방안으로 가상 ID를 이용하는 I-PIN과 e-ID 카드가 제안되었지만, 문제점은 ID와 패스워드만 알고 있다면 누구나 도용이 가능하고 오프라인에서 사용하는 플라스틱 카드의 경우 위 변조가 가능하다는 한계를 갖는다. 본 논문에서는 주민등록번호를 대체할 식별 데이터인 QR-ID를 생성하고, 이에 기반을 둔 QR-ID 카드를 제안한다. QR 코드는 인식기에 대한 제약이 적고 일부 데이터 조작만으로 새로운 QR 코드 생성이 가능하여 노출 시 새로운 ID로 갱신할 수 있으며, QR-ID는 소유자의 바이오메트릭 데이터로 암호화되어 타인이 복호화 할 수 없다.

  • RFID(Radio Frequency IDentification) is a system to identify objects and its usage is being extended to distribution, healthcare, and air&port etc. RFID is a contactless system environment, and reducing tag authentication time is important because multiple tags are identified at the same time. Studies about RFID system so far is, however, mostly to improve security vulnerability in the tag authentication process. Therefore, this paper suggests an efficient scheme to decrease the time of tag authentication which is also safe for the security of tag authentication process. The proposed scheme cuts down on the tag ID search time because it searches only the classified relevant ID in the database, which is one of many components of RFID system, by using identification bits for tag ID search. Consequently, the suggested scheme decreases process time for tag ID authentication by reducing the processing time and the load of the database. It also brings performance improvement of RFID system as it improves the energy applicability of passive tag.
