Chao, Ping-Hsia 09 July 2002 (has links)
The thesis will be established as prototype of DSP-Based motion control card with USB2.0 interface. The whole system is composed of three subsystems: 1. Windows AP¡]Application Program¡^, 2.USB2.0 development tools, and 3.DSP development tools. Many motion control commands can be transmitted from friendly AP, through USB2.0 development board, to DSP development board, for example, position, velocity and acceleration. DSP will parse and execute these commands immediately; furthermore, the course and result of processing can be sent back to host by the same route. Then AP can display the data received from target with high readability. In a word, proved by experiment, the thesis achieved the expected goal: accomplish the prototype research and development of DSP-Based motion control card with USB2.0 interface.

Partindo dos bons resultados demonstrados nessas pesquisas, foi traçada a meta para este de testar o PCG em outras áreas do design. Como primeiro passo, foi feita uma revisão tanto das metodologias de design quanto dos ramos do design para somente após escolher o design gráfico como segmento a ser testado com o PCG. Ainda nesta etapa, foi tomada a decisão de utilizar um meio-termo antes de testar o PCG com design gráfico. Este meio termo foi o design de jogos de tabuleiro que, embora teoricamente esteja dentro da área de design de jogos, apresenta peculiaridades semelhantes às do design gráfico. Com os bons resultados em design de jogos de tabuleiro, foi feito o experimento com design gráfico de estampas de camiseta. O que se pode perceber nos resultados de todos esses experimentos é que o PCG aparentemente pode ser utilizado em outras áreas do design sem perder suas características e propriedades. Todavia, a metodologia necessita ainda de mais testes tanto na parte acadêmica quanto de uma utilização contínua e prolongada na indústria para sedimentar-se em definitivo

La mesure de performance dans les cartes à puce

Cordry, Julien 30 November 2009 (has links)
La mesure de performance est utilisée dans tous les systèmes informatiques pour garantir la meilleure performance pour le plus faible coût possible. L'établissement d'outils de mesures et de métriques a permis d'établir des bases de comparaison entre ordinateurs. Bien que le monde de la carte à puce ne fasse pas exception, les questions de sécurité occupent le devant de la scène pour celles-ci. Les efforts allant vers une plus grande ouverture des tests et de la mesure de performance restent discrets. Les travaux présentés ici ont pour objectif de proposer une méthode de mesure de la performance dans les plates-formes Java Card qui occupent une part considérable du marché de la carte à puce dans le monde d’aujourd’hui. Nous étudions en détails les efforts fournis par d'autres auteurs sur le sujet de la mesure de performance et en particulier la mesure de performance sur les cartes à puce. Un grand nombre de ces travaux restent embryonnaires ou ignorent certains aspects des mesures. Un des principaux défauts de ces travaux est le manque de rapport entre les mesures effectuées et les applications généralement utilisées dans les cartes à puce. Les cartes à puce ont par ailleurs des besoins importants en termes de sécurité. Ces besoins rendent les cartes difficiles à analyser. L'approche logique consiste à considérer les cartes à puce comme des boites noires. Après l'introduction de méthodologies de mesures de performance pour les cartes à puce, nous choisirons les outils et les caractéristiques des tests que nous voulons faire subir aux cartes, et nous analyserons la confiance à accorder aux données ainsi récoltées. Enfin une application originale des cartes à puce est proposée et permet de valider certains résultats obtenus. / Performance measurements are used in computer systems to guaranty the best performance at the lowest cost. Establishing measurement tools and metrics has helped build comparison scales between computers. Smart cards are no exception. But the centred stage of the smart card industry is mostly busy with security issues. Efforts towards a better integration of performance tests are still modest. Our work focused on a better approach in estimating the execution time within Java Card platforms. Those platforms constitute a big part of the modern smart card market share especially with regards to multi-applicative environments. After introducing some methodologies to better measure the performance of Java Cards, we detail the tools and the tests that we mean to use on smart cards. We will thereafter analyze the data obtained in this way. Finally, an original application for smart cards is proposed. We used it to validate some points about the results.

A Generic Approach for Protecting Java Card™ Smart Card Against Software Attacks / Une approche générique pour protéger les cartes à puce Java Card ™ contre les attaques logicielles

Bouffard, Guillaume 10 October 2014 (has links)
De nos jours, la carte à puce est la pierre angulaire de nos usages quotidiens. En effet, elle est indispensable pour retirer de l'argent, voyager, téléphoner, ... Pour améliorer la sécurité tout en bénéficiant d'un environnement de développement facilité, la technologie Java a été adaptée pour être embarquée dans les cartes à puce. Présentée durant le milieu des années 90, cette technologie est devenue la plate-forme principale d'exécution d'applications sécurisées. De part leurs usages, ces applications contiennent des informations sensibles pouvant intéresser des personnes mal intentionnées.Dans le monde de la carte à puce, les concepteurs d'attaques et de contre-mesures se livrent une guerre sans fin. Afin d'avoir une vue générique de toutes les attaques possibles, nous proposons d'utiliser les arbres de fautes. Cette approche, inspirée de l'analyse de sûreté, aide à comprendre et à implémenter tous les événements désirables et non désirables existants. Nous appliquons cette méthode pour l'analyse de vulnérabilité Java Card. Pour cela, nous définissons des propriétés qui devront être garanties: l'intégrité et la confidentialité des données et du code contenus dans la carte à puce. Dans cette thèse, nous nous sommes focalisés sur l'intégrité du code des applications. En effet, une perturbation de cet élément peut corrompre les autres propriétés. En modélisant les conditions, nous avons découvert de nouveaux chemins d'attaques permettant d'accéder au contenu de la carte. Pour empêcher ces nouvelles attaques, nous présentons de nouvelles contre-mesures pour prévenir les éléments indésirables définis dans les arbres de fautes. / Smart cards are the keystone of various applications which we daily use: pay money for travel, phone, etc. To improve the security of this device with a friendly development environment, the Java technology has been designed to be embedded in a smart card. Introduce in the mid-nineties, this technology becomes nowadays the leading application platform in the world. As a smart card embeds critical information, evil-minded people are interested to attack this device. In smart card domain, attacks and countermeasures are advancing at a fast rate. In order to have a generic view of all the attacks, we propose to use the Fault Tree Analysis. This method used in safety analysis helps to understand and implement all the desirable and undesirable events existing in this domain. We apply this method to Java Card vulnerability analysis. We define the properties that must be ensured: integrity and confidentiality of smart card data and code. During this thesis, we focused on the integrity property, especially on the code integrity. Indeed, a perturbation on this element can break each other properties. By modelling the conditions, we discovered new attack paths to get access to the smart card contents. We introduce new countermeasures to mitigate the undesirable events defined in the tree models.

校園智慧卡系統應用與發展之研究 / A Study of the Application and Expansion of Campus Smart Card

游麗珠, You, Lai-Ju Unknown Date (has links)
政府推動IC金融卡業務已近八年,然其成效仍十分有限。國內金融機構為區隔消費市場,以IC金融卡延伸之應用功能,結合校園識別證件、圖書證、學生證、停車證…等功能,與各大學院校共同發行校園智慧卡,並以IC金融卡之電子錢、預付電話等功能作為校園內各項支付之工具。民國86年政大智慧卡率先發行,迄今已有二、三十家大學院校發行校園智慧卡,累積發卡量達近百萬張,惟其刷卡消費之實績一直未如預期,且發卡量亦呈趨緩之趨勢,這與金融機構積極推展校園卡,由年輕族群帶動消費市場、改變國人消費習性之理想有所違背。本研究即針對國內IC金融卡之推廣瓶頸、及金融機構推廣校園智慧卡所遭遇之問題進行探討與分析,自財金資訊公司蒐集國內金融機構IC金融卡發卡量與營運量統計資料,以探索性研究方法,進行次級資料分析,以期發現校園智慧卡在推動過程中所遭遇的問題,並提出改善之建議,使校園智慧卡達到多卡合一之功效,同時對未來政府推動各類多功能智慧卡提出建議方案。 / The government implements the IC Card business for almost eight years, but the effects are very limited. To segment consumer market, financial institutions and some universities in Taiwan co-issue Campus Smart Cards. This card has extensible functions of IC Card and can be used as campus identification card, including library ID, student ID, parking ID, etc. Furthermore, Campus Smart Card provides some functions of IC Card that can be used as payment tools on campus, such as electronic money and prepaid phone. In 1997, National Chengchi University took the lead to issue smart cards. To date, about 30 universities have issued Campus Smart Cards for almost million people. However, the total expenditure of Campus Smart Cards is not so good as expected earlier, and the volume of card issue declines. At the beginning, financial institutions issued Campus Smart Cards aggressively to let young people stimulate consumer market and to change consumers' behavior. But the situation doesn't achieve the goal. This paper discusses and analyzes the bottleneck of IC Card issue and the problems that financial institutions face when they push Campus Smart Cards. The research data are collected from FISC (Financial Information Service Co., Ltd.), including volume of card issue and card operation for IC Card. A discovery research method is used to do secondary data analysis. The purposes of this research are listed below: To find out problems during the implementation of Campus Smart Card and provide suggestions. Secondly, try to let Campus Smart Card be a popular multi-function card. Also, provide workable suggestions for the government to implement multi-function Smart Cards in the future.

Don, Michael L. 10 1900 (has links)
ITC/USA 2011 Conference Proceedings / The Forty-Seventh Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2011 / Bally's Las Vegas, Las Vegas, Nevada / This paper presents three telemetry techniques demonstrated on an affordable precision mortar that allowed the guidance, navigation, and control (GNC) system to be effectively analyzed. The first is a technique for the real-time integration and extraction of GPS data into a sensor telemetry stream. The second is a method for increasing telemetry bandwidth by saving a short period of high rate data and then broadcasting it over the rest of the flight test. Lastly, I present an on-board data storage implementation using a MicroSD card.

Designing Credit Card ABS in Taiwan

趙振宏, Chao, Chen-Hung Unknown Date (has links)
Three decades ago, the first securitization product was introduced to the investing public in the United States by federal agencies and similar products showed up in Taiwan in 2002. It is a brand new concept for investors in Taiwan and material differences between the west and the east should be considered thoroughly. This research focus on must-knows and critical techniques of securitization of credit card receivables in Taiwan. The researcher discovered that, the competitiveness of originators is one crucial factor for credit card securitization to survive during serious conditions. Without the ability to refill declining credit card receivables in asset pool of securitization transactions, early amortization will be triggered and that’s where case closed. Cash flow forecasting model is another important player in credit card securitization. By predicting future cash flows needed and generated, originators can reap the most profit. However, the variables in this magic model are not easy to find. Through multiple analyses and one simulated case, the researcher found that the most important factors are yield rate, loss rate, repurchase rate, and monthly payment rate. / Three decades ago, the first securitization product was introduced to the investing public in the United States by federal agencies and similar products showed up in Taiwan in 2002.
