  text: Spamming remains a form of Internet abuse, which burdens the Internet infrastructure,
    is generally regarded as an annoyance, and is said to cause economic harm to the
    tune of about several billion US\$ per year. Many technological, organizational,
    and legislative anti-spam measures have already been proposed and implemented,
    but have not led to any substantial decrease in the number of spam e-mails. We
    propose here a new infrastructure framework that combines several anti-spam measures
    in a framework that features both a technological and an organizational facet.
    The key element of our infrastructure is a new organizational unit that reliably
    and transparently limits he number of e-mails that can be sent per day and per
    account. This paper first gives an overview of the framework, then it provides
    technological and organizational details of the infrastructure, the deployment
    of which depends to a large degree on its acceptance and propagation by the ICANN,
    the ISOC, and by large e-mail service providers. Finally, the paper discusses
    the limitations and drawbacks of the proposed framework.

  text: Spam e-mails have become a serious technological and economic problem. Up
    to now, by deploying complementary anti-spam measures, we have been reasonably
    able to withstand spam e-mails and use the Internet for regular communication.
    However, if we are to avert the danger of losing the Internet e-mail service in
    its capacity as a valuable, free and worldwide medium of open communication, anti-spam
    activities should be performed more systematically than is currently the case
    regarding the mainly heuristic, anti-spam measures in place. A formal framework,
    within which the existing delivery routes that a spam e-mail may take, and anti-spam
    measures and their effectiveness can be investigated, will perhaps encourage a
    shift in methodology and pave the way for new, holistic anti-spam measures. This
    paper presents a model of the Internet e-mail infrastructure as a directed graph
    and a deterministic finite automaton and draws on automata theory to formally
    derive the spam delivery routes. The most important anti-spam measures are then
    described. Methods controlling only specific delivery routes are evaluated in
    terms of how effectively they cover the modeled e-mail infrastructure; methods
    operating independently of any particular routes receive a more general assessment.

  text: 'Email communication is encumbered with a mass of email messages which their
    recipients have neither requested nor require. Even worse, the impacts of these
    messages are far from being simply an annoyance, as they also involve economic
    damage. This manuscript examines the resource ?email addresses?, which is vital
    for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization
    for implementing an empirical analysis of the usage of email addresses placed
    on the Internet are proposed here. Their objective is to assess, on a quantitative
    basis, the extent of the current harassment and its development over time. This
    ?framework? is intended to be extensible to measuring the effectiveness of address-obscuring
    techniques. The implementation of a pilot honeypot is described, which led to
    key findings, some of them being: (1) Web placements attract more than two-thirds
    (70\%) of all honeypot spam emails, followed by newsgroup placements (28.6\%)
    and newsletter subscriptions (1.4\%), (2) the proportions of spam relating to
    the email addresses? top-level domain can be statistically assumed to be uniformly
    distributed, (3) More than 43\% of addresses on the web have been abused, whereas
    about 27\% was the case for addresses on newsgroups and only about 4\% was the
    case for addresses used for a newsletter subscription, (4) Regarding the development
    of email addresses? attractiveness for spammers over time, the service ?web sites?
    features a negative linear relationship, whereas the service ?Usenet? hows a negative
    exponential relationship. (5) Only 1.54\% of the spam emails showed an interrelation
    between the topic of the spam email and that of the location where the recipient?s
    address was placed, so that spammers are assumed to send their emails in a ?context
    insensitive? manner. The results of the empirical analysis motivate the need for
    the protection of email addresses through obscuration. We analyze this need by
    formulating requirements for address obscuring techniques and we reveal to which
    extent today?s most relevant approaches fulfill these requirements.'

  text: Spam has become one of the most annoying and costly phenomenon in the Internet.
    Valid e-mail addresses belong to the most valuable resources of spammers, but
    little is known about spammers? behavior when collecting and harvesting addresses
    and spammers? capabilities and interest in carefully directed, consumer-oriented
    marketing have not been explored yet. Gaining insight into spammers? ways to obtain
    and (mis)use e-mail addresses is useful in many ways, e.g. for the assessment
    of the effectiveness of address obscuring techniques and the usability and necessity
    of hiding e-mail addresses on the Internet. This paper presents a spam honeypot
    project in progress addressing these issues by systematically placing e-mail addresses
    in the Internet and analyzing received e-mails. The honeypot?s conceptual framework,
    its implementation, and first empirical results are presented. Finally, an outlook
    on further work and activities is provided.

  text: Voting via the Internet has become a feasible option for political as well
    as non-political ballots. However, there are many obstacles which have to be overcome,
    especially legal restrictions have to be transformed into technical and security
    solutions. The article starts with a brief presentation of advantages and disadvantages
    of Internet ballots and presents application fields and pilot schemes. Then, technological
    security aspects are derived due to democratic basic principles. Especially the
    applied voting procedures are critical in security terms. Hence, the most relevant
    cryptographic protocols are presented and their drawbacks and shortcomings are
    identified. However, this article does not propose a new voting protocol. Beyond
    fixing cryptographic procedures for ballots, more elements are to be specified,
    e.g. responsibilities and rights of involved authorities or security precautions
    regarding hardware and software. For this reason, a structural security framework
    for electronic voting systems is presented which can be used for their composition
    and analysis.

  text: Spam als unerwünschte Massen-E-Mail hat die Grenze von der Belästigung zur
    ökonomischen Relevanz längst überschritten. Ihr relativer Anteil am gesamten,
    weltweiten E-Mail-Aufkommen stieg in den vergangenen Jahren auf mehr als 50% im
    Jahr 2003. Es entstehen jährlich volkswirtschaftliche Schäden in Milliardenhöhe.
    Zur Bekämpfung des Spam-Problems werden neben gesetzlichen Regelungen vor allem
    technische Lösungen eingesetzt, bei denen das Blockieren und Filtern von E-Mails
    in praktisch eingesetzten Anti-Spam-Systemen dominieren. Dieser Artikel führt
    in die Spam-Problematik ein und beschreibt, bewertet und klassifiziert die derzeit
    bedeutendsten Verfahren zur Bekämpfung von Spam.

  text: Spam as unsolicited e-mail to a large number of recipients is known to ecome
    an increasingly disturbing and costly issue of electronic business and internet
    traffic. Mainly technical-oriented approaches are applied with a focus on blocking,
    filtering, and authentication mechanisms based on the domain name system. They
    come along with different drawbacks and have all low effectiveness in common.
    The article sketches these approaches, shows its limitations, and proposes an
    account-based approach where the number of e-mails per day and account is restricted.

  text: Remote Internet voting systems still suffer from many security problems which
    rely on the clients, the servers, and the network connections. Denial-ofservice
    attacks and viruses still belong to the most challenging security issues. Projects
    and studies like the ?Voting Technology Project? of CALTECH and MIT or SERVE of
    the US Department of Defense set up to gain experience evidence many of the notional
    weaknesses of current Internet voting systems.

  text: Voting via the Internet is part of electronic government and electronic democracy.
    However, there are many obstacles which have to be overcome, especially legal
    restrictions have to be transformed into technical and security solutions. In
    the first part the article discusses advantages and disadvantages of Internet
    elections, shows different application fields, and presents important international
    pilot schemes (political and business ones). in the second part, due to democratic
    basic principles, technological security aspects are worked out.

  text: 'Zusammenfassung: Im Rahmen des E-Governments werden zunehmend Internetwahlen
    diskutiert. Der Beitrag diskutiert zunächst die Vor- und Nachteile derartiger
    Wahlen und zeigt Anwendungsgebiete sowie durchgeführte Pilotprojekte im politischen
    wie auch wirtschaftlichen Bereich auf. Im Rahmen eines Anforderungssystems werden
    anschließend aus demokratischen Wahlgrundsätzen sicherheitstechnologische Anforderungen
    herausgearbeitet. Zu deren Adressierung werden kryptographischen Wahlkonzepte
    herangezogen, von denen die wichtigsten vorgestellt werden. Aufgrund der Komplexität
    der Anforderungslandschaft wird ein sicherheitstechnologisches Strukturmodell
    vorgestellt, das insbesondere dazu dient, die Sicherheit(skomponenten) eines Wahlsystems
    systematisch mit den Anforderungen abzugleichen. Der Artikel schließt mit einem
    Ausblick auf notwendige Untersuchungen.'

  text: Bei der Online-Marktforschung lässt sich mit Hilfe virtueller 3D-Welten das
    Konsumentenverhalten beobachten. Da die Struktur der dabei anfallenden Daten multidimensional
    ist und die marktforschungsrelevanten Anfragen eine hohe OLAP-Affinität aufweisen,
    wurde hierzu im Rahmen des Forschungsprojekts Benevit ein Data Warehouse konzipiert
    und realisiert. Im Rahmen einer Standardisierung der Protokollierung von Konsumentenaktivitäten
    und deren prototypischen Realisierung erwies sich der Data Warehouse/OLAP-Ansatz
    zur Speicherung, Analyse und Präsentation der Marktforschungsdaten als adäquates
    Instrumentenbündel.

  text: 'Mit dem elektronischen Papier wird in der Displayforschung ein neuer materialtechnologischer
    Ansatz verfolgt: Elektronisches Papier besteht aus einer dünnen, flexiblen Folie,
    in der farbige Pigmente mittels elektrischer Felder ausgerichtet werden. Die Vorteile
    gegenüber traditionellen Technologien wie beispielsweise LCD-Displays bestehen
    zum einen in niedrigeren Herstellungskosten (niedrigere Produktionskosten und
    geringere Materialkosten) und einem geringeren Gewicht. Zum anderen entsteht eine
    bessere Lesbarkeit, da sich Reflexion, Kontrast und mögliche Betrachtungswinkel
    verbessern bzw. vergrößern. Diese Potenziale können bei Anzeigetafeln, Computerdisplays
    und mobilen Endgeräten ausgeschöpft werden. Mit der Eigenschaft, fast beliebige
    Materialien als Trägermedium zu verwenden, öffnet sich auch die Anwendungsmöglichkeit
    des biegsamen, elektronischen Mediums für Zeitungen und Zeitschriften. Die US-Unternehmen
    E Ink und Gyricon Media bieten eine zunehmend größere Produktpalette mit elektronischem
    Papier an.'
