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.

Concerns about food safety continue to rise and under this situation, governments of some countries have reinforced their regulations more strictly for food safety. In order to prevent food safety incidents or, at least to minimize the impact, the preparedness is very important. As a consequence of this, traceability system has become an essential tool for food safety. Recently, it requires more prevention-based food safety control system. One of the most generally used systems for food safety control is Hazard Analysis and Critical Control Point (HACCP). Both traceability and HACCP systems can be integrated through Electronic Product Code (EPC) Sensor Network technologies which have four value propositions. In this paper, we will introduce the concept of product and process traceability system (P2TS) through the integration of three systems to improve food safety management. The final aim is to find out the added values of the P2TS.

Currently, research on network functions virtualization focuses on using microservices in cloud environments. Previous studies primarily focused on communication between nodes in physical infrastructure. Until now, there is no sufficient research on group key management in virtual environments. The service is composed of microservices that change dynamically according to the virtual service. There are dependencies for microservices on changing the group membership of the service. There is also a high possibility that various security threats, such as data leakage, communication surveillance, and privacy exposure, may occur in interactive communication with microservices. In this study, we propose an ID-based group key exchange (idGKE) mechanism between microservices as one group. idGKE defines the microservices' schemes: group key gen, join group, leave group, and multiple group join. We experiment in a real environment to evaluate the performance of the proposed mechanism. The proposed mechanism ensures an essential requirement for group key management such as secrecy, sustainability, and performance, improving virtual environment security.

Korean Identification card or driver license is usually used to verify one's identity in Korea. These are also used as an adult certification. Since the form of these ID card is an analog and it needs to be checked with naked eyes, it might be used maliciously. Someone who's got someone else's ID card can do other things. Therefore, it must be reported rapidly when ID card is lost or stolen. The most serious problem might be occurred when they do not recognize and report the loss. They might suffer from pecuniary or mental damage such as opening a mobile phone service, providing loan or credit card, opening a personal checking account, etc. Thus, this study suggests and compares the ways of avoiding these problems. First, the most effective way is to send the authorization code via mobile phones in consideration of build-up period and cost. The person in charge of business processing department using ID card sends the authorization code via registered mobile phone. The owners submits it to the person and their identifications are confirmed. Next effective way is that the person in charge of business processing department using ID card sends text messages via registered mobile phone. Lastly, the most ineffective way is to introduce and implement the electronic ID card ultimately even though it is expensive and takes a long time to build up the system.

ID federation provides users various benefits such as employing multiple services with only single authentication and mitigating management burden of service providers that individually preserve account information of users. To keep up with this international trend, efforts for making the domestic ID federation is ongoing to provide users in the domestic research and education community seamless network connectivity and to support tetherless extension of research environment. In this paper, we analyze the foreign ID federation policies and compare them as a underlying work for making the domestic ID federation. Besides, we suggest some contents that should be included in the domestic ID federation policy. To activate the coming domestic ID federation, we need to first have a well-made federation policy. Then, we need to aggressively promote the domestic ID federation, develop various and fascinating services, and build a convenient support system for technology and service.

생산자 폐기 책임 규제 강화로 인하여, 제조업 영역이 제품 제조(BOL) 뿐만 아니라 사용, 보수(MOL)와 폐기(EOL)까지 확장 수명주기로 확대 되고 있다. 또한 EOL상에서 개별 제품에 대한 제품 복원 관리 시스템 (PRMS: Product Recovery Management System)에 관한 연구가 활발히 진행 되고 있다. 그러나 BOL, MOL과 EOL간의 정보 단절 문제, MOL상의 정보를 저장하고 사용할 수 없었던 문제는 EOL관리의 자동화를 저해한 큰 요인이다. 최근 유비쿼터스 기술의 발달로 개별 제품 추적이 가능해 졌지만, EOC 등의 식별부호(ID)만으로는 PRMS에 필요한 제품 정보를 얻을 수 없다. 본 논문에서는 제품 ID로부터 MOL상의 정보를 연결하고, 국제표준 기반 정보모델을 이용하는 PRMS를 개발한다. 이를 위해: (1) PRMS에 필요한 정보를 국제표준(ISO10303-239 등)을 기반으로 모델링하고, (2) 제품 ID를 통해 MOL상의 정보를 수집하여 제품 복원에 대한 의사결정을 수행할 수 있는 PRMS를 설계하고, (3) 시제품 구현을 통해 제안된 데이터 모델 및 시스템의 유효성을 검증한다.

SCADA (Supervisory Control and Data Acquisition) systems for remote monitoring, data acquisition and control are applied to major industrial infrastructures including power, water and railroad. Recently, there are many researches on key management scheme for secure communication due to change to the open network environment. These systems are located at far distances and are connected to the main control center through various types of communication methods. Due to the nature of these systems, they are becoming the significant targets of cyber attack. We propose an efficient key management scheme which is established on ID-based cryptosystem without an expensive computation on MTU (Master Terminal Unit), Sub-MTU, and RTU (Remote Terminal Unit). The proposed method is secure and effective in key management among multiple legitimate devices.
