The reason why you want to do that is because it makes it + % possible to detect if visited websites are being impersonated or not. + % + % For example, an attacker may want to impersonate a website to steal a + % user's credit card number. It is also helpful to de-anonymize a Tor user. + % + % So, our work focus on adding support for Certificate Transparency in Tor + % Browser. We do that while focusing on two key properties. + % + % The proposed solution should be _privacy-preserving_. We achieve this + % because of and how we use Tor. + % + % The proposed solution should also be incrementally-deployable, and in the + % end have a stronger threat model than current Certificate Transparency + % deployments in Chrome and Safari that trust so-called CT logs blindly. + % + % In more detail, our incrementally-deployable design goes from: + % pairs of CT logs that are trusted blindly, to + % at least one CT log is trusted blindly, to + % no CT log that is trusted blindly. + % + % It is fair to say that we have a strong threat model where the attacker + % even has a zero-day exploit against Tor Browser. In spite of this very + % strong threat model, the involved performance overhead is modest. + % + % For more detail, please refer to our paper and/or watch the presentation. + % + \mktitle{Breaking down the title} + \begin{columns} + \begin{column}{0.55\textwidth} + \begin{itemize} + \item Support Certificate Transparency in Tor + \item Privacy-Preserving + \item Incrementally-deployable + \end{itemize} + \end{column} + \begin{column}{0.45\textwidth} + \centering\includegraphics[width=.5\columnwidth]{img/tb} + \end{column} + \end{columns} + \footnotetext[1]{\tiny{Paper: \url{https://petsymposium.org/2021/files/papers/issue2/popets-2021-0024.pdf}}} + \footnotetext[2]{\tiny{Presentation: \url{https://www.youtube.com/watch?v=f7yDJOd6g3U}}} +\end{frame} diff --git a/slides/2021-surprise/src/preamble.tex b/slides/2021-surprise/src/preamble.tex new file mode 100644 index 0000000..4021351 --- /dev/null +++ b/slides/2021-surprise/src/preamble.tex @@ -0,0 +1,113 @@ +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% Packages % +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\usepackage[utf8]{inputenc} + +\usepackage[ + lambda, advantage, operators, sets, adversary, landau, probability, notions, + logic, ff, mm, primitives, events, complexity, asymptotics, keys +]{cryptocode} + +\usepackage{rotate} +\usepackage{graphicx} +\usepackage{mathtools} +\usepackage{amsmath} +\usepackage{amssymb} +\usepackage{flowchart} +\usepackage{smartdiagram} +\usepackage{pifont} +\usepackage{wasysym} +\usepackage{graphicx} +\usepackage{color} +\usepackage{drawstack} +\usepackage{tikz} +\usepackage{tikz-qtree} +\usetikzlibrary{ + arrows,% + decorations.markings,% + backgrounds,% + calc,% + fit,% + positioning,% + shapes.misc,% + shadows,% + shapes.arrows,% + shapes,% + snakes,% +} +\usepackage{booktabs} +\usepackage{smartdiagram} +%\usepackage{floatrow}% this one causes error on arch for some reason +\usepackage[position=bottom]{subfig} % environment for nested figures + +\usepackage{xcolor} +\definecolor{darkGreen}{HTML}{008000} +\definecolor{darkBlue}{HTML}{2809B2} +\definecolor{darkRed}{HTML}{CC0000} +\definecolor{darkGray}{HTML}{808080} +\definecolor{darkOrange}{HTML}{D77D00} +\definecolor{darkPurple}{HTML}{800080} +\colorlet{lightGray}{gray!33} +\colorlet{lightYellow}{yellow!50} +\definecolor{darkGreen}{HTML}{008000} +\definecolor{darkBlue}{HTML}{2809B2} +\definecolor{darkRed}{HTML}{CC0000} + +\usepackage{hyperref} +\hypersetup{ + colorlinks = true, % Color links instead of boxes + urlcolor = darkBlue, % Color external hyper links + linkcolor = darkBlue, % Color internal links + citecolor = darkBlue, % Color citations +} + +% Figures, tables and code +\usepackage{booktabs} +\usepackage{colortbl} +\usepackage{flowchart} +\usepackage{adjustbox} +\usepackage{listings} + +\lstdefinestyle{CStyle}{ + backgroundcolor=\color{lightGray!25}, + commentstyle=\color{darkGreen}, + keywordstyle=\color{darkBlue}, + numberstyle=\tiny\color{darkRed}, + stringstyle=\color{darkPurple}, + basicstyle=\footnotesize, + breakatwhitespace=false, + breaklines=false, + captionpos=b, + keepspaces=true, + numbers=left, + numbersep=5pt, + showspaces=false, + showstringspaces=false, + showtabs=false, + tabsize=2, + language=C, + morekeywords={size_t,def,in,zip,True,False,ord,u8,u64}, +} + +\setbeamertemplate{itemize item}[circle] +\setbeamertemplate{itemize subitem}[default] +\setbeamertemplate{caption}[numbered] + +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +% Defines % +%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% +\makeatletter +\let\@@magyar@captionfix\relax %needed for \titlefloatright +\makeatother + +\newcommand{\tyes}{\textcolor{darkGreen}{\ding{51}}} +\newcommand{\tno}{\textcolor{darkRed}{\ding{55}}} +\newcommand{\burl}[1]{\tiny{\url{#1}}} +\newcommand{\TODO}[1]{\textcolor{red}{TODO}: #1} +\newcommand{\floatright}[1]{\hspace{0pt plus 1 filll}#1$\;$} + +\def\rding{\rotatebox[origin=c]{-91}{\ding{224}}} +\def\lding{\rotatebox[origin=c]{91}{\ding{224}}} + +% TODO: fix this properly... +\newcommand{\mktitle}[1]{\centering\textbf{\large#1}\vfill\normalsize} diff --git a/slides/2021-surprise/src/titlepage.tex b/slides/2021-surprise/src/titlepage.tex new file mode 100644 index 0000000..9b18039 --- /dev/null +++ b/slides/2021-surprise/src/titlepage.tex @@ -0,0 +1,3 @@ +\begin{frame} + \titlepage +\end{frame} |
