  • In the case of the password-based PKI technology, because it protects by using the password which is easy that user memorizes the private key, he has the problem about the password exposure. In addition, in the system of electronic bidding, the illegal use using the authentic certificate of the others increases. Recently, in order to solve this problem, the research about the PKI technology using the biometrics is actively progressed. If the bio information which the user inputs for the bio authentication is converted to the template, the digest access authentication in which the security is strengthened than the existing authentication technology can be built. Therefore, in this paper, we had designed and developed the system of electronic bidding which it uses the most widely used fingerprint information in the biometrics, it stores the user fingerprint information and certificate in the fingerprint security token and can authenticate the user. In case of using the system of electronic bidding of the public key infrastructure using the fingerprint information proposed in this paper the agent bid problem that it uses the certificate of the others in not only user authentication intensification but also system of electronic bidding can be concluded.

  • The purpose of this study is to examine the legal standards of agreements on the origin of liability and the relevant laws in Korea, to suggest implications for custom authorities and traders wishing to benefit from preferential tariff via FTA, citing the excluded cases of related FTA preferences (court cases and administrative judgments). In order to examine the provisions related to supporting evidence of the origin of liability in FTA, we examined FTAs agreed between Korea and EU, EFTA, ASEAN, U.S., and India relevant to FTA Special Customs Act, court cases and administrative judgements. If verifying the origin to protect the fair trade order impedes to promote utilizing FTA, solutions will need to be suggested. If FTA preference is exempted due to verifying the origin by the import customs authorities, the importer shall pay the income tax calculated in accordance with the general tax rate. This is because the certificate of origin confirmed during verification process is different from the actual origin. In most agreements, the exporter (the producer) shall issue the certificate of origin and since the importer has no other option than obtaining the certificate of origin from the exporter, it may face consequences such as declined credibility from the custom authorities in addition to being disqualified for FTA preferential, if the certificate of origin received from the exporter has flaws. On the other hand, the exporter cannot help but being punished by the customs authorities due to issuing defective origin certificates, but it doesn't have conventionary liabilities for damages incurred to the importer. As a result, importers are forced to pursue legal proceedings to claim damages to exporters or to give up FTA preference. As FTA is increasingly utilized, the number and amount of origin verification in Korea has continuously been increasing while administrative judgements indicates other FTA exporters doesn't seem to gain any support in utilizing FTA like Korea does. It has been 8 years since full-scale supports in FTA launched and now is the time to introduce more efficient and intensive FTA support system In this regard, it is desirable to conduct comprehensive verification on export Next, an institutions that assures FTA-based exports should be established in order to compensate the importer's damages that may occur from disqualified certificate of origin issued by the exporter.

  • Medical certificate is a document to demonstrate a patient's health status, made up and signed by a physician, dentist, or oriental physician who attended the patient. It serves as an evidence in many official process including civil or criminal law suit, especially for one's personal injury. The Korean legal system also acknowledges and protects the evidentiary function of medical certificate by mandating physicians etc. to issue medical certificate in good faith and only when they personally attended the patient, and by criminally punishing them when they do not comply with these legal requirements. There are some reasons, however, that medical certificates often do not reflect the true health status of the patient: When physicians attend the patient and collect information regarding the health status of the patient, their priority is and should be the most cost-effective way to meet the health needs of the patient. It does not necessarily correspond to the accurate examination of the health status of the patient. Even when the patient's report on the history of the illness or the injury seems suspicious, physicians might have to avoid disproving it because that kind of attitude might harm the rapport between the physician and the patient. All these can distort the perception of the physicians and this distortion can be reproduced in the medical certificate they made up. Some of these problems might be resolved or at least enhanced by introducing new form of medical certificate which would guide physicians to reveal the nature, factual and theoretical grounds, and the limit of their findings more accurately. Others, however, would not be able to address, because it stems from the conflict between the physician's primary duty, duty to be loyal to the patient's life and health, and his secondary duty to serve as a public or neutral witness on the health status of the patient, and when both values or duties conflict with each other, they should choose the duty to the patient sacrificing the duty to the public or the court.

  • In this paper, we have interested in cooperative intelligent transport system and autonomous driving system, and focused on analysis of the characteristics of Cooperative Awareness Message (CAM) and Decentralized Environmental Notification Basis Service (DENM) message, which is key delivery message among cooperative intelligent transport system (C-ITS) characteristics for research objectivity. For research method, we also described V2X communication, and also analyzed the security certificate and header structure of CAM and DENM messages. We described CAM message, which is a message informing the position and status of the vehicle. And the DENM message is presented a message informing an event such as a vehicle accident, and analysis security communication, which is supported services. According to standard analysis result, 186 bits or 275 bits are used. In addition to the security header and the certificate format used for vehicle communication, we have gained the certificate verification procedure for vehicles and PKI characteristics for vehicles. Also We derived the characteristics and transmission capability of the security synchronization pattern required for V2X secure communication. Therefore when it is considered for communication service of DENM and CAM in the C-ITS environment, this paper may be meaningful result.

  • The Web or Mobile channel of previous Web access authentication system for a payment only provides the authentication of remote users, and does not provide the authentication between a user and a bank/financial institution. Therefore, this paper proposes the Transaction Certificate Mode(TCM) for a payment which can preserve the mutual authentication between a user and a bank/financial institution for Web-based payment systems. The proposed system has designed for wireless network instead of Secure Electronic Transaction (SET) designed for wired electronic transaction. In addition, this system with TCM is able to support an account-based transaction for wireless networks instead of a disadvantage of SET such as a card-based transaction for wired networks. Therefore, customers can check their balances without logging on their bank's web site again due to mutual authentication between a customer and his bank/financial institution.

  • The distribution of standing wreaths has reached about 7.1 million per year and the size of the standing wreath market is estimated to be at least 700 billion won. Among them, 20 to 30 percent are estimated to be reused, resulting in damage to flowerfarms' sales of 110 to 160 billion won per year. Due to the unique characteristics of conventional 3-tier standing wreaths in terms of transportation and installation, companies that lack design expertise have monopolized local distribution markets, and the issue of illegally using standing wreaths has been raised. These issues have highlighted the need for developing new designs and establishing a distribution system to expand the consumption of flowers. This study was carried out to identify consumers' perception of reused standing wreaths and the current systems introduced to prevent the distribution of reused standing wreaths such as the real-name standing wreath production system, the authenticity certificate system, and new standing wreaths. The results of a consumer survey showed that consumers' perception of reused standing wreaths has been high and that reused standing wreaths need to be actively regulated to establish fair trade order and protect consumers' rights. Although the effectiveness of the real-name system, the authenticity certificate system, and new standing wreaths was found to be insufficient, the introduction of these systems was essential and necessary for continuous promotion through broadcasting media.

  • An aircraft engine is considered as the most important element among aircraft systems. Thus type certificate is required for an aircraft engine to ensure its safety under appropriate airworthiness standard. U.S. FAR Part 33 or European CS-E is widely adopted as an airworthiness standard for aircraft engines, and other representative countries of the world established own airworthiness standards under their regulations. In this paper, we compared differences of the requirements between FAR Part 33 and CS-E, and proposed the rulemaking items to harmonize Korean Airworthiness Standard for Aircraft Engines with worldwide standards and to contribute to growth of aviation industry.

  • This study describes the Federal Aviation Administration(FAA) certification policy for approving the use of Type II, III, and IV deicing/anti-icing fluids on small category airplanes. These fluids can be characterized as non-Newtonian, pseudo-plastic fluids, also known as "thickened" fluids. Deicing fluids are used before takeoff to remove frost or ice contamination, while anti-icing fluids are used before takeoff to prevent frost or ice contamination from occurring for a period of time(referred to as "holdover time") after application. Thickened deicing/anti-icing fluids can affect airplane performance and handling characteristics and their residue may cause stiff or frozen flight controls. This study also describes an approval process that may be used by type certificate holders and applicants for a type certificate under parts 23 to support operational use of these fluids on their airplanes.
