The Tor Project, Inc is a non-profit... + +% XXX: In this position paper, we describe the current and potential issues with + +Dangers and opportunities with resepect to browsing the Internet anonymously are +often tied to the browser itself and not its underlying transport protocols: +canvas fingerprinting, plugin enumeration and linking users via the DOM storage +are just a few of the means the browser offers for trying to single users out. +And even things like cookies and referrers, although belonging strictly speaking +to HTTP, the transport protocol powering the web, are usually seen in the +context of the browser itself as its additional policies shape the particular +tracking potential of these and other transport related features. +This is not much different for features in HTTP/2 although, compared to +HTTP/1.1, it has a growing list of tracking risks that should be addressed in +the specification itself. We discuss some of them below proposing ways to take +these and other risks into account in future HTTP specifications. + +Apart from the dangers we just hinted at, beginning with HTTP/2 opportunities +emerge as well: Using HTTP/2's flow control could make it easier to defend +against adversaries sniffing a user's encrypted traffic and trying to extract +information out of it by means of website traffic fingerprinting. We discuss +current limitations and potential improvements for HTTP/3. + +\section{A Short Tracking Guide(1)} + + +If we are talking about tracking on the Internet then we mainly have third-party +tracking in mind. In this scenario the attacker has basically two mechanisms +available: identifier based tracking (e.g. using cookies or cache cookies) and +fingerprinting a user's device or environment. + +Additionally, we may encounter powerful parties that see a lot of a user's +traffic due to being in a privileged position (e.g. search engines). They don't +necessarily need to bother with third party tracking and would still be able to +learn a lot of a user's details by correlating traffic which is endangering her +anonymity. + +The defenses we develop in Tor Browser are: + +1) Binding identifiers to the URL bar domain. This is retaining functionality +while preventing cross-origin identifier linkability: saving third party +identifiers (e.g. via DOM storage) in a URL bar domain context does not make +them available in a different URL bar domain context. +2) Making users as uniform as possible while not breaking functionality. +3) Providing a "New Identity" button that is clearing all browser state and +giving the user a clean, new session. + + +\subsection{User Tracking with HTTP} + +\subsection{Re-Using Connections} +Coalescing connections might allow tracking users across origins just by means +of HTTP. Together with a long keep-alive this might make it easy to correlate a +lot of cross-domain traffic of a privacy conscious user even if she has +JavaScript and third-party cookies disabled. Granted, having this feature in +HTTP/2 is a big deal especially with respect to CDNs. But still we think +allowing implementers to provide means to mitigate the issue directly in the +specification seems worthwhile to do. This does not imply avoiding coalescing +connections in the first place. Not at all. One could think about proposing a +middle ground safe-guarding privacy while still providing advantages speed- and +resource-wise: connections should not be reused across different URL bar +domains. + +\subsection{Timing Side-Channels} + +PING and SETTINGS frames are acknowledged immediately by the client which might +give servers the option to collect information about a client via timing +side-channels. It is true, there are other means an attacker could use for the +same purpose but they are either visible in the browser UI or users can disable +them. As a countermeasure the specification could at least allow jitter in some +cases (PING frames come to mind). If that is not an option one could specify +that a client may close the connection to prevent timing side-channel attacks. + + +\section{A Short Website Traffic Fingerprinting Guide} + +
