본 연구는 중계형 서비스 기반 원격 컴퓨터 제어 시스템(RS_RCCS Relay Sevice-based Remote Computing Control System)에서 참여자 사이에 패스워드를 이용한 인증센터가 필요 없이 독립적 인증을 제공할 수 있는 프로토콜을 제안하고 이를 설계하고자 한다. RS_RCCS 에서의 인증센터가 존재하지 않는 인증구조에서 구조적으로 원격 서비스 요청자들이 다수의 관리자와의 상호 인증 과정이 요구되며 이에 예상되는 패스워드 공격에 안전하게 보호될 수 있는 프로토콜이 필요로 한다. 이에 본 연구는 효율적인 RS_RCCS에 대한 인증 설정과 이에 대한 프로토콜을 연구하여 원격 제어 부분의 자원 관리의 유용성에 도움이 되고자 한다. This study is to propose and design a protocol that offers independent authentication with no necessity of certification authority using password between participants in RS_RCCS(Relay Service-based Remote Computing Control System). In RS_RCCS without authentication center that remote service requesters have mutual authentication with many service managers, there needs for a protocol protected from password attacks. Hereupon, this study is to offer an efficient authentication setting and a protocol for RS_RCCS and helpful for the usefulness of resource management.

There are mainly two ways to make a payment method for an e-business transaction: making e-money using encoded algorithms and designing payment protocol using encoding techniques. This paper studies interrupting elements to a payment systems, security requirement, and underlying technology for security. This paper analyzes a security mechanisms in terms of the security requirement for a major payment method. The results of this analysis can be used to devise comprehensive techniques and strategies in designing the protocol for a safe and effective Payment systems.

This study is to describe security technique of a smartcard as an important security equipment in a recent information network. Smartcard is rising up as a equipment which is excellent in security such as user authentication, access control, and information storage and control. As electronic business transactions are briskly carried on, the possibility of forgery and alteration by network hacking is on the increase because of the mercenary motives. For this reason, I propose a security system equipped with a multiple authentication system to protect forgery and alteration through a study related with security technique of a smartcard.

Penalty tax of basic law that has been revised in December 30, 2006 has been amended to tax 40 percent on no report and under-reporting in unjustifiable way. This revision is a punitive regulation that reflects the national tax service's will to not sit back and watch taxpayers' intentional tax evasion by imposing a heavier tax burden, and it raised penalty tax rate that has been applied leniently compared to foreign countries. Therefore, this study examines how changes in penalty tax rate affected faithful tax report and in what level the punitive penalty tax rate should be legislated so that the effect of the penalty tax rate can be maximized by performing empirical analysis on the effect on income tax rate reporting standard of self-employed businesses before and after the time the penalty tax rate increased dramatically from 33.3% to 300% based on the items.

This research is aimed at grouping for the extent to which the workers' job satisfaction influences productivity with a view to improving theirs, shedding light on the difference between the workers' concepts of job satisfaction and those of the executives of the matter in terms of the statistic characteristics of individuals and coming up with efficient measures to put the Korean tax accounting offices into smooth operation. The paper is suggesting a total of eight hypotheses, and the researcher tested those with the help of difference analyses and a regression analysis. The findings reveal that there was a difference in productivity in accordance with academic background, positions and total number years of work, etc. but tat there was no difference in gender. And superiors and pay among the factors of job satisfaction influenced productivity, whereas promotion and coworkers didn't. The worker subjects and the executive subjects turned out to differ in terms of pay levels, the welfare of the works, and the level of their ability to carry out their business in regard to the actual situation of tax accounting offices in Korea.
