Public key infrastructure(PKI), principle technology of the certificate, is a security technology providing functions such as identification, non-repudiation, and anti-forgery of electronic documents on the Internet. Our government and financial organizations use PKI authentication using ActiveX to prevent security accident on the Internet service. However, like ActiveX, plug-in technology is vulnerable to security and inconvenience since it is only serviceable to certain browser. Therefore, the research on HTML5 authentication system has been conducted actively. Recently, domestic bank introduced PKI authentication complying with web standard for the first time. However, it still has inconvenience to register a certification on each website because of same origin policy of web storage. This paper proposes the certificate based SSO protocol that complying with web standard to provide user authentication using certificate on several sites by going around same origin policy and its security proof.

Critical infrastructures (energy, information technology and communications, banking, transportation, public government services, etc.) are now more vital to modern society. Citizens, businesses and governments all rely on an array of interlinked physical and information infrastructures to satisfy their needs and perform their daily operations. At the same time, these infrastructures are becoming increasingly interdependent, such that failure of one of them can often propagate and result in domino effects. Recent dramatic episodes, from 9/11 to the Madrid train bombings, the April 2010 ash cloud the power cuts in Korea in 2011, and the cyber-attacks have highlighted the need for a comprehensive, internationally coordinated policy for the protection of critical infrastructures. For the purposes of this report, we define critical infrastructure as infrastructure whose failure would result in substantial damage to society and/or the economy.

Since the theories of service quality were introduced in Korea, they have been applied to the various organizations, such as hospital, hotel travel agency bank, telecom company, and even retail market. Compared with these areas, however studies on the service qualify in educational institutions have been scarcely conducted. Also, higher educational service challenges user-oriented education system of the 21st century concept of Service quality from the theories of market economy. The purpose of this study is to identify the dimensions of educational and administrative service, and their influence upon the satisfaction and value on service quality, and formulate the service quality model based on the revised quality dimensions using SERVQUAL measuring method, to find out the most influential factors upon the service qualify among these factors. This study also suggests proper measures for improving service quality.

As a result of comparing and analyzing the related legislation of each nation, more superior legislative systems should be made to cope with a number of terrors effectively. And also it is required to devise some concrete regulations such as the following in superior legislative systems. First, because it is hard to collect information on terrorism and watch over suspects according to Communication Privacy Protection Law. More in-depth discussion into the issue of surveillance is needed for the protection of lives and property, although public concerns of privacy are a valid point of contention. Second, it is necessary to take complementary measures on immigration as surveillance, since the current Immigration Control Law has restrictions in many ways to hinder efforts to root out terrorists. Third, under the current law on financial activities, it is impossible to block influx of terror financing. Therefore it is necessary to come up with ways of making the punishment procedures. Fourth, considering that convicted terrorists get punished under the standard procedures and precedents, it is required to clearly differentiate between what the terror acts are and what terrorist groups are. Fifth, it is necessary to make use of the private security system to enhance the security system of national facilities.

In this era of changing system, we may learn lesson from newly developed Uniform Electronic Transation Act(UETA) in 1999. Korea has its counterpart as the Basic Electronic Transaction Act and Electronic Signature Act made by 1999. While UETA stresses on transaction law between individuals, that of Korean stresses on the role of government in electronic transaction. Both laws have the common definitions as electronic record, electronic signature, however, UETA has its own definitions such as automated transaction, computer program, electronic agent, information, information processing system, and security procedure. Especially, transferable record in section 16 is one of the most unique concept which Korean law does not provide. Korean government is planning to introduce electronic note in the near future, which will make unprecedented reform in Korean financial industry. Since Korean law does not have such a concept as electronic note, revision of the law is expected soon. Korean law has its specialty which puts stress on cyber mall, authentication agency, and consumer protection. In U.S., the interpretation of law by court is important when they have disputes according to common law traditon. Studies on cases on disputes in U.S. is needed most for Korean application.

Amidst the acceleration of digital transformation across various sectors, the financial market is increasingly focusing on the development of digital and electronic payment methods, including currency. Among these, Central Bank Digital Currencies (CBDC) are emerging as future digital currencies that could replace physical cash. They are stable, not subject to value fluctuation, and can be exchanged one-to-one with existing physical currencies. Recently, both domestic and international efforts are underway in researching and developing CBDCs. However, current CBDC systems face scalability issues such as delays in processing large transactions, response times, and network congestion. To build a universal CBDC system, it is crucial to resolve these scalability issues, including the low throughput and network overload problems inherent in existing blockchain technologies. Therefore, this study proposes a solution based on reinforcement learning for handling large-scale data in a CBDC environment, aiming to improve throughput and reduce network congestion. The proposed technology can increase throughput by more than 64 times and reduce network congestion by over 20% compared to existing systems.
