자바카드를 위한 ECDSA의 구현

이상곤,김윤근 東西大學校 2001 동서논문집 Vol.7 No.-

In this paper, we developed elliptic curve crypto system software package runnable on a java card and implemented ECDSA algorithm. Two versions, 16-bit version and 32bit version, are developed. The package includes addition, multiplication, inversion, and polynonlial modular arithmethic libaranes based on F2˝ and polynomial bases. The package also includes addition, subtraction, and scalar multiplication arithmetlc libraries over affine coordinate of elliptical curve. We used this library to implement ECDSA.

길쌈부호의 부등비트오율이 고려된 DPCM의 신호대 잡음비

李相坤,崔閏喆,文相在 慶北大學校 1990 論文集 Vol.49 No.-

This paper presents that the signal to noise ratio of DPCM is theoretically examined in the case that bit error rates of individual bits consisting of the information word are different from one another. It is investigated through the computer simulation where the inputs are speech signal. The SNR performance of DPCM can be improved by using the property of the unequal bit error probabliity.

As it is known for, GanGyeongDoGam was an important department of the publication of Buddhist classics in the early Chosun Dynasty. Despite Buddhist classics in Chinese is about three times more than those annotated in Korean, Buddhist classics of GanGyongDoGam are invaluable documents that show the first forms of Korean because it is annotated in Korean which was neglected as ′OenMun′ GanGyongDoGam was established with special care of the King Sejo. For 11 years of GanGyongDoGam, it's delicate works of annotation in Korean are as great as any other works of the entire Chosun Dynasty. Based on 《Annals of the Chosu Dynasty》, in this main article we considered the achievements of GanGyongDoGam such as building temples, the management of Buddhist events, the importation of books, besides the publication of Buddhist classics. And we came to the conclusion that GanGyongDoGam was not just a department of publication of Buddhist classics. It's remarkable that GanGyongDoGam is affected by Sejo's personal interest not just by the national purpose of publication from the establishment to the operation. At the beginning of GanGyongDoGam, there's the record which emphasizes that the publication of the Buddhist classics is carrying on the work left unfinished by the previous King Sejong. But as time goes by GanGyongDoGam turned into the general department carrying on the whole buddhist works. So the ministers of the previous dynasty made a strong protest about this. What is worse, Sejo, in the end of his period, GanGyeongDoGam for a political aim. After he died, for his reason, the issue about the abolition of GanGyeongDoGam came to the front. The ministers of the previous dynasty who hadn't dared to tell the King Sejo popsed that GanGyeongDoGam be abolished. At last, the King Seongjong had to abolish GanGyeongDoGam . As the abolishment of GanGyeongDoGam, the publication that the annotation in Korean of the Buddhist classics could not be continued. For the time being, a few of Buddhist classics were annotated in Korean by the queen mothers. In the early Chosun Dynasty, the annotation in Korean had been leaded by the royal family but in the middle of the age, it was published by local temples all over the country. While GanGyeongDoGam had annotated the Buddhist classics through the diligent study and delicate annotation of the original texts, they simply give the reading of Chinese characters in hangul. Therefore the annotation in Korean of the buddhist classics couldn't make a progress. Moreover, it is inconvenient that the delicate publication of the annotation in Korean of the Buddhist classics not continue to exist since the abolishment of GanGyeongDoGam.

필리핀 친족 정치체제에서 여성의 정치참여 한계에 관한 연구

남궁곤,조윤주 이화여자대학교 한국여성연구원 2008 여성학논집 Vol.25 No.1

친족 정치는 필리핀 여성들의 정치참여를 제고시키는 자원이자 원동력으로 간주된다. 친족 정치는 다른 한편으로는 실질적인 정치과정에서 오히려 필리핀 여성정치를 왜곡시키고 그 발전 가능성을 저지한다. 이 연구는 필리핀 친족 정치를 사회자본 특성과 가부장제 성격의 이중적 속성을 가진 것으로 파악하여 어떤 측면에서 친족 정치가 여성의 정치참여를 촉진하면서 또한 제약하는지 분석한다. 필리핀 친족 정치는 여성들의 정치진입 과정에 이중적 영향력을 행사한다. 친족집단 내에 존재하는 사회자본을 통해 여성들은 다른 친족들로부터 적극적인 후원을 얻는다. 대중들과 정치가문 사이에 형성된 사회자본은 정치가문 출신 여성들의 정치진출을 용이하게 한다. 그러나 이것은 지배가문 여성들에게만 해당되는 것으로서 대중 여성들의 정치진출을 저해한다. 지배가문 여성들 역시 남성과 동등한 입장에서 정치에 참여하는 것이 아니라, 사적 가부장성에 의해 비공식 정치영역에 집중함으로서 성별 귀속적인 분리장벽을 경험한다. 또한 남성 친족들과의 관계에서 종속되고 의존적인 성향을 습득한 친족여성들은 주로 선거에 출마한 친족남성들의 보조자 역할만을 담당하거나, 부득이하게 친족남성들이 선거에 출마하지 못할 때 대신 정치에 진출하는 한계를 보여준다. 친족 정치와 그것의 가부장적 성격으로 인한 폐해는 여성들의 공직 수행과정에도 계속해서 나타난다. 친족남성대신 급조되어 출마한 여성정치인들은 주체적인 동기부여나 기본적 자질, 능력 등이 구비되지 않은 경우가 많아 상대적으로 남성정치인들보다 미숙한 모습을 보인다. 또한 친족여성이 정치에 진출할 수 있도록 후원한 가문구성원들은 서로 간에 존재하는 사회자본을 바탕으로 자신들의 투자 결과를 기대하게 되면서 친족 여성에게 이권과 관련된 압력을 가한다. 이러한 폐해와 함께 그것이 지닌 가부장성에 의해 여성정치인들은 자신의 매력이나 감성적 수단들을 사용하여 남성정치인들을 설득하는 종속적 태도를 보이거나, 가부장적 편견에 의해 한정된 영역에서만 활동하게 된다. According to the statistics, Philippine women appear to actively participate in the politics. The existing discussion agrees that kinship politics is the source and the power of women to participate in politics. However, this argument overlooks the fact that kinship politics can distort and hinder the possibility of the development of women's politics in the Philippines. This argument has an implication for understanding Philippine kinship politics in respect to the dual characteristics-social capital and patriarchy. In what way does kinship politics either accelerate or constrain the political participation of women. The characteristic of Philippine kinship politics exercises dual(bi-dimensional) influence on the process for women's entering politics. Women obtain strong support from the members in kinship group through the social capital existing in the kinship group. On the other hand, the social capital between mass public and political families facilitates political participation of women from political families. This mechanism constitutes a good environment for women politicians. However, this case applies only to women from political families, making it a very rare case for women with an ordinary family background. On the other hand, even women with such a good family background experience gender-oriented security barriers as they concentrate on the informal political area instead of the general political area on equal terms with men. This situation is caused by a private patriarchal system. In addition, the kinship women who have become dependent on and subordinated to men usually limit themselves playing the role of an assistant for male electoral candidates or participating in politics only to substitute for men when they are not available. The side effect caused by the patriarchal character of the kinship politics also appears in the process of women’s government service. Being nominated to substitute for male candidates, women politicians often lack a self-motive or basic capability as a politician and often show unprofessional conduct in comparison to male politicians. The members of the kinship who claim their share of the investment based on the trust-social capital which connects them, pressure their family women politician, regarding their various interests. With these abuses of the kinship politics, its patriarchal character exerts an evil influence on women’s political careers. Women are likely to make use of their personal attractiveness or other emotional means to persuade male politicians and to become subordinated to them. At the same time they conduct limited activities due to the patriarchal prejudice.

In this paper, we propose a prime code and a new encryption algorithm as its application. The characteristics of prime numbers with irregular distribution and uniqueness are used to generate the prime code. Based on the prime code, an encryption algorithm for secret key is presented. Since the algorithm requires simpler operations than existing encryption such as DES, the burden form hardware implementation of the encryption and decryption process is alleviated. The algorithm proposed was modeled in VHDL, verified by means of simulation, and implemented with an Altera FPGA chip.

We studied the effect of mass transfer in a dryer on the condensation of amino resin mould material and the curing characteristics, and investigated the drying rate, the moisture and the curing fluidity according th the variations of the temperature and the drying media recycle volume which affects the mass transfer in the drying process. So, the result are summarized as follows: ① As the drying temperature increased to 70℃, 80℃ and 90℃ respectively, the drying rate became fast. ② In the same final drying time, the higher the drying temperature became, the more the moisture content of the urea resin mould material inceased. ③ Accordingly as the drying temperature increased, the moisture content of the drying material suddenly decreased in short drying time, but the moisture content increased when the drying time was between 80 minute and 120 minutes. ④ As the drying temperature increased, the curing fluidity of amino resin mould meterial decreased. ⑤ As the recycle volume of the drying media increased, the curing fluidity decreased.

암호화 칩의 구현 및 이용에 관한 연구

류승석,오재곤,정연모 慶熙大學校 1998 論文集 Vol.27 No.-

Since data security problems are very important in the information age, encryption algorithms have been studied for a long time. The GOST(Gosudarstvennyi Standard or Government Standard) algorithm as a data encryption algorithm with a 256-bit key is a 64-bit block algorithm developed in the former Soviet Union. In this paper, we describe how to design an encryption chip based on the GOST algorithm. In addition, the GOST algorithm is compared with the DES(Data Encryption Standard) algorithm which has been used as a conventional data encryption algorithm in modeling techniques and their performance. The GOST algorithm whose key size is relatively longer than that of the DES algorithm, has been expanded to get better performance, modeled in VHDL, and simulated for implementation. In addition, the algorithm was implemented with a FPGA chip. Finally how to use the encryption chip in HDTV design for image protection is presented.
