+% SIG-ALTERNATE DOCUMENT STYLE
+% G.K.M. Tobin August-October 1999
+% adapted from ARTICLE document style by Ken Traub, Olin Shivers
+% also using elements of esub2acm.cls
+% HEAVILY MODIFIED, SUBSEQUENTLY, BY GERRY MURRAY 2000
+% ARTICLE DOCUMENT STYLE -- Released 16 March 1988
+% for LaTeX version 2.09
+% Copyright (C) 1988 by Leslie Lamport
+%
+%
+%%% sig-alternate.cls is an 'ALTERNATE' document style for producing
+%%% two-column camera-ready pages for ACM conferences.
+%%% THIS FILE DOES NOT STRICTLY ADHERE TO THE SIGS (BOARD-ENDORSED)
+%%% PROCEEDINGS STYLE. It has been designed to produce a 'tighter'
+%%% paper in response to concerns over page budgets.
+%%% The main features of this style are:
+%%%
+%%% 1) Two columns.
+%%% 2) Side and top margins of 4.5pc, bottom margin of 6pc, column gutter of
+%%% 2pc, hence columns are 20pc wide and 55.5pc tall. (6pc =3D 1in, approx)
+%%% 3) First page has title information, and an extra 6pc of space at the
+%%% bottom of the first column for the ACM copyright notice.
+%%% 4) Text is 9pt on 10pt baselines; titles (except main) are 9pt bold.
+%%%
+%%%
+%%% There are a few restrictions you must observe:
+%%%
+%%% 1) You cannot change the font size; ACM wants you to use 9pt.
+%%% 3) You must start your paper with the \maketitle command. Prior to the
+%%% \maketitle you must have \title and \author commands. If you have a
+%%% \date command it will be ignored; no date appears on the paper, since
+%%% the proceedings will have a date on the front cover.
+%%% 4) Marginal paragraphs, tables of contents, lists of figures and tables,
+%%% and page headings are all forbidden.
+%%% 5) The `figure' environment will produce a figure one column wide; if you
+%%% want one that is two columns wide, use `figure*'.
+%%%
+%
+%%% Copyright Space:
+%%% This style automatically reserves 1" blank space at the bottom of page 1/
+%%% column 1. This space can optionally be filled with some text using the
+%%% \toappear{...} command. If used, this command must be BEFORE the \maketitle
+%%% command. If this command is defined AND [preprint] is on, then the
+%%% space is filled with the {...} text (at the bottom); otherwise, it is
+%%% blank. If you use \toappearbox{...} instead of \toappear{...} then a
+%%% box will be drawn around the text (if [preprint] is on).
+%%%
+%%% A typical usage looks like this:
+%%% \toappear{To appear in the Ninth AES Conference on Medievil Lithuanian
+%%% Embalming Technique, June 1991, Alfaretta, Georgia.}
+%%% This will be included in the preprint, and left out of the conference
+%%% version.
+%%%
+%%% WARNING:
+%%% Some dvi-ps converters heuristically allow chars to drift from their
+%%% true positions a few pixels. This may be noticeable with the 9pt sans-serif
+%%% bold font used for section headers.
+%%% You may turn this hackery off via the -e option:
+%%% dvips -e 0 foo.dvi >foo.ps
+%%%

+\begin{abstract}
+
+Tor is a popular tool for online anonymity that currently does not have a
+standard graphical user interface. We present Vidalia, an open source,
+cross-platform GUI for Tor. We discuss some of the design decisions we have
+made in Vidalia, as well as what we have found users expect in a Tor GUI.
+
+\end{abstract}
+
+\section{Introduction}
+\label{sec:intro}
+
+Tor is a system designed to allow users to anonymously
+communicate on the Internet, such as browsing the Web or chatting on IRC. The
+Tor software itself usually runs in the background as a daemon process on the
+user's computer and does not have a user interface beyond its log files.
+
+Vidalia was initially developed for a Tor GUI design competition in 2006 and
+is intended to provide a simple, easy-to-use interface for Tor. We wanted to
+create an interface that simplifies the process of setting up and managing
+Tor, and gives interested users the ability to learn more about what their Tor
+process is doing and where their traffic is going.
+
+Vidalia has been publicly available under the GNU General Public License since
+March 2006. While we do not have any formal numbers as to how many users
+Vidalia currently has, download statistics in mid-2006 suggested Vidalia had
+around one thousand users and we expect that number to have increased since
+then. Here we discuss some of the design decisions we have made in Vidalia
+and some lessons we learned during Vidalia's on-going development.
+
+
+\section{Vidalia}
+\label{sec:vidalia}
+
+The Tor software is highly portable and we felt that a viable Tor GUI must
+also support as many platforms as possible. We chose to develop Vidalia in C++
+using the Qt GUI toolkit, which enabled us to more easily build a
+cross-platform interface that uses native interface widgets on many platforms
+and window managers, including Windows, Mac OS X, Gnome, and KDE.
+
+Due to space limitations, we have omitted actual screenshots of Vidalia's
+interface. Instead, interested readers can find current screenshots on our
+website at\\ {\tt www.vidalia-project.net}.
+
+\subsection{Installation}
+
+To simplify installation and configuration of the applications most commonly
+used in conjunction with Tor, we provide a ``bundled'' installation package
+for Windows that includes Vidalia, Tor, Privoxy, and Torbutton pre-configured
+to work together. Privoxy is an HTTP proxy that can filter out potentially
+harmful HTML features, such as Javascript. Torbutton is a very simple
+Firefox extension that lets users quickly enable and disable their Web
+browser's use of Tor. We also provide a similar bundle for Mac OS X, but it
+does not yet include Torbutton.
+
+We have not yet had any requests for similar bundled installers on other
+platforms, likely because users of Linux or other Unix variants often appear
+to be more comfortable installing and configuring software packages than
+Windows users.
+
+\subsection{Main Interface}
+
+Vidalia launches Tor as a background process and places an onion-shaped icon
+in the user's system tray or dock that changes color to indicate Tor's status.
+A green onion indicates Tor is running, a dark onion with a red `X' indicates
+Tor is not running, and red or yellow onions represent intermediate states. A
+tooltip is displayed if the user mouses over the tray icon and gives a text
+description of Tor's status. The user can click the icon to bring up a menu
+of additional actions, such as viewing the status of their anonymous
+connections.
+
+Windows users are accustomed to looking to their system tray for application
+icons or status indicators and found the unobtrusive tray icon to be
+preferable to the large command prompt window that typically appears when Tor
+is run without Vidalia\footnote{Windows NT/2000/XP users can run Tor in the
+background as a Windows service, but properly configuring Tor as a service is
+often challenging for novice users.}.
+
+There were, however, several problems with relying on only a tray icon for the
+primary application interface. Windows tray icons are limited to only $16
+\times 16$ pixels and it was sometimes difficult for users to identify what
+Vidalia's tray icon indicated, or even that the icon is an onion. We also
+found users on platforms other than Windows were not accustomed to looking for
+an icon in their system's notification area and might not initially notice
+Vidalia was even running. Some window managers, such as Enlightenment, by
+default do not have {\it any} form of a system tray.
+
+We recently added a ``control panel'' dialog that appears when Vidalia is
+first run. The control panel contains links to other commonly accessed Vidalia
+features, much like the tray menu. The dialog also displays a larger onion
+icon to more clearly indicate Tor's status, along with a more detailed
+description ({\it e.g.}, ``Tor is running. You can now configure your
+applications to use Tor''). On platforms that do have a system tray, the user
+can optionally start Vidalia with the control panel initially hidden.
+
+\subsection{Network Visualization}
+
+The primary interest of most users is in whether or not their application
+traffic is being anonymized through Tor, but we have found many users are also
+interested in {\it where} their traffic is going. To answer both questions, we
+added a dialog that displays the status of the user's anonymous connections
+and plots their paths on a map of the world. The network map also makes it
+clearer to users that Tor differs from a simple one-hop proxy, since they can
+see the multiple hops their traffic takes as it traverses the Tor network.
+
+%Showing users the exact servers that are used to transport their anonymous
+%connections has lead to some confusion. Tor chooses a small set of reliable
+%servers on the network, called {\it entry guards}, to use as the first hop of
+%a client's anonymous connections. Some users assume Tor chooses all hops in
+%their path uniformly randomly and become concerned when they see some entry
+%guards appearing in many of their circuits.
+
+A common feature request from users is the ability to customize their routes
+through the Tor network. For example, some users want to be able to say ``only
+use servers whose bandwidth is in the top 25\% of all servers in the Tor
+network'' or ``make all of my traffic appear to originate in the United
+States.'' Tor has a fairly complex algorithm for choosing paths through the
+network that attempts to balance anonymity, application performance, and
+network load-balancing. Consequently, we decided not to implement features
+that let users significantly alter Tor's path selection due to the negative
+effects they can easily have on the user's anonymity and the Tor network.
+
+\subsection{Running a Server}
+
+The Tor network is composed of hundreds of servers run by volunteers around
+the world. We wanted to make it easy for users to contribute to the Tor
+network by simplifying the process of setting up a Tor server. Vidalia's
+control panel has a button labeled ``Setup Relaying'' that takes users to a
+dialog that helps them set up their own Tor server. Users can then simply
+click a checkbox labeled ``Relay traffic for the Tor network'' and Vidalia
+will configure Tor to act as a server using sensible defaults.
+
+Optionally, users can further define how their server should behave by
+limiting the amount of traffic they are willing to relay and restricting
+the types of services that can be accessed through their server, known as an
+{\it exit policy}. Users can select the approximate speed of their own network
+connection and Vidalia will choose a reasonable bandwidth limit for their
+server. There is also a small set of checkboxes for common Internet services,
+such as ``Websites'' and ``Instant Messaging'', that users can check or
+uncheck to allow or disallow access to those resources from their server.
+Vidalia will then set Tor's exit policy according to the checkboxes.
+
+%This approach to server configuration is easier to understand for users who
+%often confuse KBps and Kbps when setting their bandwidth limits and may not
+%even know what a ``port'' is, let alone what ports are used for common
+%Internet applications.
+
+\subsection{Message Log}
+
+Tor's own method of communicating with the user is via log messages, many of
+which may not make sense to the user. Unfortunately, we find the terse
+log messages to still be somewhat of a ``necessary evil'' since they can
+provide the best information to developers when users ask for troubleshooting
+support on Tor's mailing list or IRC channel.
+
+Vidalia attempts to make dealing with Tor's logs a little more palpable for
+novice users by displaying log messages in a more user-friendly table that can
+be sorted, searched, and filtered based on message severity. Important
+messages are highlighted depending on their severity, with critical {\it
+error} messages appearing in red and less important {\it warning} messages
+appearing in yellow. Log messages can also be saved to a file or copied from
+the table and pasted into other applications, which has been useful for users
+when they are seeking assistance.
+
+\subsection{Internationalization}
+
+We have found that good support for multiple languages is an important
+component of a Tor GUI, since many of Tor's users are not native English
+speakers. Vidalia currently supports 12 languages in addition to English, and
+all translations have been contributed by Vidalia users. Designing the
+interface with translators in mind has also helped us keep the user-visible
+strings simple and avoid Tor-specific jargon. As an example, the ``New
+Identity'' button was initially labeled ``New Nym'', but ``nym'' did not
+translate well to other languages.
+
+
+\section{Future Improvements}
+\label{sec:future-work}
+
+\subsection{Improved Status Notifications}
+
+Recent versions of Tor have the ability to notify GUIs of important status
+updates, such as when one of the user's applications may be using an unsafe
+version of the SOCKS protocol that could leak the destination of the
+application's ``anonymous'' connection. Currently, such notifications
+typically appear only in the message log, which the user may not notice.
+
+We want to make Vidalia aware of these events and be able to present them more
+prominently to the user, without being too obtrusive. On platforms that
+support system tray icons, we might have a message bubble appear near the
+tray icon letting the user know about important Tor status changes. For other
+systems without standard system notification areas, a simple message box will
+likely have to suffice.
+
+\subsection{Tighter Application Integration}
+
+While our bundled installation packages make installing and configuring the
+multiple software packages typically used with Tor nearly trivial, we have
+found it can be confusing to users {\it why} each component is useful. Some
+users mistakenly think Vidalia is the application that actually provides their
+anonymity, while others do not understand the added security Privoxy can
+provide.
+
+It may be much simpler from the user's perspective if we combined Vidalia,
+Tor, and Privoxy into a single application. A good first step would be for
+Vidalia to launch and manage Privoxy, much like it currently does for Tor.
+
