This paper is designed to search the new alternatives to supplement the inconvenience of the traditional written ballot method which is executed every early semester to select the class board at the school. It is prepared on the based the results of the design and implement of the wired/wireless inter-working mobile electronic voting system where the students can participate in the real-time class board selection and the decision-making utilizing the mobile phones, PDA and PC they commonly have. It is time when we should consider introducing the electronic voting system, to minimize the students' inconvenience and the subsequent missing class, having to wait in the long line in the designated place to select the class board at every election season. This system enables the students to participate wherever they are other than the common place as well. Further, this research will provide the opportunity to think over the new school election culture in line with the age of Ubiquitous, as well as the useful means in the field to promote the active participation of the parents and students in the students' self-administration, decision-making necessary at the schools.

인터넷의 급속한 발전과 유비쿼터스 컴퓨팅 능력이 발전됨에 따라 이러한 정보 인프라에서의 프라이버시 보호에 대한 요구가 더욱 증가하고 있다. 프라이버시 보호를 위한 핵심 기술로서 익명성 기술이 사용하고 있으며, 익명성 기술의 역기능을 방지하기 위해서 익명성 제어 기술을 사용하고 있다. 국외에서는 이미 익명성 및 익명성 제어 기술을 다양한 분야에서 연구ㆍ적용하고 있으나 국내에서는 전자투표 시스템 이외의 분야에서는 연구가 미진한 실정이다. 이에 본고에서는 국외 익명성 및 익명성 제어 모델인 익명 이메일 시스템, 익명 출판 시스템, 전자투표 시스템 및 익명 브라우징 시스템을 소개하고 분석하였다. 또한, 각 시스템별로 시스템 구성객체, 익명성 제공과 관련 없는 요구사항, 익명성 제공 서비스의 요구사항, 익명성 제어 서비스를 위한 요구사항을 기술하여 국내 익명성 및 익명성 제어 시스템 개발에 도움이 되고자 한다.

This study aims at examining what factors have an effect on congressional voting behaviors. In particular, the study closely investigates the Whole Reform Bill on the Law of Local Educational Self-Governing because the bill attracts a lot of attentions. Above all, the bill contains direct election of superintendents of educational affairs and members of a board of education. Likewise, the education committee is converted into a standing committee of the local assembly due to the passage of the bill. The reason the study mainly focuses on the bill is because in general, bills on the floor are approved with significant high in favor; however, the bill was passed with opposition. The study examines factors having an influence on legislators' voting decision. Statistical results show that the ruling party played a significant role in passing the bill. Also, the results exhibit that legislators with high careers and proportional members were in favor of the bill compared with other legislators. Although the study examined only particular bill passed by the National Assembly, it gave an opportunity to look at voting behaviors of legislators. Hopefully, the study contributes to the understanding of congressional voting behaviors.

전자현금(Electronic Cash)이나 전자투표(Electornic Vote)에의 응용을 목적으로 Chaum에 의해 처음으로 RSA 기반의 은닉서명(Blind Signature) 개념을 제안하였다[1]. 휴대폰, 스마트카드와 같은 작은 용량의 메모리와 연산 능력을 가진 장치에서는 연산량이 작은 은닉서명 프로토콜을 필요로 한다. 본 논문에서는 사전계산과 효율적인 이차잉여 선택 방법을 이용하여 Rabin 기반 전자서명 방법에 은닉서명 개념을 도입하여 효율적인 Rabin 기반의 은닉 서명 프로토콜을 제안한다.

In 2010, Sebe et al. proposed an efficient and lightweight mixnet scheme for remote voting systems. The scheme based on a cryptographic secure hash function, does not require complex and costly zero-knowledge proofs of their correct mixing operations, thus they claimed that their scheme is simple and efficient. In this paper, we propose more efficient and fast mixnet scheme than Sebe et al.'s scheme under the same assumption.

Mix network plays a key role in electronic voting to preserve anonymity and lots of mixnet schemes have been proposed so far. However, they requires complex and costly zero-knowledge proofs to provide their correct mixing operations. In 2010, Seb$\acute{e}$ et al. proposed an efficient and lightweight mixnet scheme based on a cryptographic secure hash function instead of zero-knowledge proofs. In this paper, we present a more efficient and faster mixnet scheme than Seb$\acute{e}$ et al.'s scheme under the same assumption. Also, our scheme is secure.
