<h1>About carlo von lynX</h1>
<h2>Why am I talking here?</h2>
<ul class="incremental">
<li>20 years of messaging & chat protocol design</li>
<li>/me etc.</li>
<li>PSYC: federated & multicasting</li>
<li>then Jabber came</li>
<li>PSYC good for business, open source delayed</li>
<li>back then, servers were reliable</li>
</ul>
</div>
<div class="slide">
<h1>Don't Trust Servers</h1>
<h2>Hardware Servers are vulnerable</h2>
<ul class="incremental">
<li>client/server architecture: data resides on servers</li>
<li>federation: data visible on even more servers</li>
<li>memory access via bus sniffing</li>
<li>no shutdown necessary</li>
<li>automated memory image analysis proven</li>
<li>eat-inside or take-away</li>
</ul>
</div>
<div class="slide">
<h1>Don't Trust Virtual Machines</h1>
<h2>Commodity Servers are VMs</h2>
<ul class="incremental">
<li>vulnerable cryptography</li>
<li>memory can be monitored</li>
<li>controlling system accessible by observers</li>
<li>automated monitoring of federated social networks</li>
<li>anti-terror legislation possible</li>
<li>even if <em>your</em> server is at home</li>
</ul>
</div>
<div class="slide">
<h1>Privacy vs. Paranoia</h1>
<h2>How Much Privacy Is Enough? 1/2</h2>
<ul class="incremental">
<li>just to the intended recipients (e2e encryption)</li>
<li>packet size padding (unobservability)</li>
<li>flexible number of anonymization hops</li>
<li>optional intentional delay</li>
</ul>
</div>
<div class="slide">
<h1>Privacy vs. Paranoia</h1>
<h2>How Much Privacy Is Enough? 2/2</h2>
<ul class="incremental">
<li>forward secrecy</li>
<li>deniability (a log is no proof of nothing)</li>
<li>private subscription lists (not on a server)</li>
<li>robust and resilient against attacks</li>
</ul>
</div>
<div class="slide">
<h1>It's A Question Of Trust</h1>
<h2>Social Onion Routing</h2>
<ul class="incremental">
<li>trust relationship between nodes</li>
<li>multihop provides anonymization</li>
<li>motivation to provide "servers" as fast routers</li>
<li>my server is me, so you can trust my server</li>
<li>"P2P" a lot faster over servers</li>
<li>servers agnostically maintain messages (and data)</li>
<!-- li>irony: role switch between servers and routers</li -->
</ul>
</div>
<div class="slide">
<h1>Portability & Acceptance</h1>
<h2>Lightweight Daemon</h2>
<ul class="incremental">
<li>personal devices and home routers</li>
<li>lightweight for embedded and mobile</li>
<li>lightweight for background daemon use</li>
<li>compiled language</li>
<li>more likely to get included in OS distros</li>
</ul>
</div>
<div class="slide">
<h1>Architecture</h1>
<h2>Technology</h2>
<ul class="incremental">
<li>"Enhanced" P2P with servers as agnostic routers</li>
<li>GNUnet as a framework: privacy, VPN, meshnet</li>
<li>TUM, learned from I2P, Freenet...</li>
<li>social graph discovery instead of DHT</li>
<li>no file sharing, no big traffic</li>
<li>PSYC on top</li>
<!-- <li>Multicast distribution for scalability (later)</li> -->
</ul>
</div>
<div class="slide">
<h1>PSYC vs XML and JSON</h1>
<ul class="incremental">
<li>extensible: semantically rich</li>
<li>binary/encrypted data capable</li>
<li>efficient as a binary format</li>
<li>table shows parsing speed in milliseconds:</li>
</ul>

<h1>One Too Many</h1>
<h2>Multicasting for Scalability</h2>
<ul class="incremental">
<li>social = one-to-many | many-to-many</li>
<li>round robin distribution = slow (SMTP)</li>
<li>HTTP is one-to-one, query/response</li>
<li>IP Multicast fails (router table overflow)</li>
<li>IRC and NNTP do/did multicast, but have other problems</li>
<li>XMPP has a trust issue (says the XSF)</li>
</ul>
</div>
<div class="slide">
<h1>Flexibility</h1>
<h2>Framework Architecture</h2>
<ul class="incremental">
<li>a truly private communications backend</li>
<li>social applications to be built on top</li>
<li>emulations of the 'open standards' possible</li>
<li>OStatus, WebID, RDF, even the Twitter API</li>
<li>optional modules for XMPP, IRC available</li>
<li>Activity Streams</li>
</ul>
</div>
<div class="slide">
<h1>Dissemination</h1>
<h2>Hard to beat Faceboogle</h2>
<ul class="incremental">
<li>since we need to go onto every computer anyway..</li>
<li>offer something Faceboogle can't provide?</li>
<li>exchanging files between friends sucks</li>
<li>USB sticks, e-mail, file hosters, skype, MSN, DropBox (brrr!)</li>
<li>WTF is 'Secure Share' ?</li>
</ul>
</div>
<div class="slide">
<h1>Desktop Integration</h1>
<h2>'Secure Share' Function</h2>
<ul class="incremental">
<li>right mouse button click (context menu)</li>
<li>share a file to a channel of subscribers</li>
<li>appears in their file system soon</li>
<li>realtime or delayed notification</li>
<li>no permission dialogs</li>
<li>shipped by default in your free OS?</li>
</ul>
</div>
<div class="slide">
<h1>Secure Share Feature Set</h1>
<h2>Features of Prototype Edition</h2>
<ul>
<li>Messaging, Subscriptions, Status Update</li>
<li>File Exchange, VPN, Software Distribution</li>
</ul>
<h2>Later Features</h2>
<ul>

<h1>A bad idea whose time has come?</h1>
<h2>End-to-end Encryption in the Browser!!1!11</h2>
<br/>
<ul class="incremental">
<li>User interface comes from the server.
<li>Web browser does what the server says.
<li>Server corrupted? It can steal your data.
<li>Only static install helps. Still:
<li>Bad cryptography, bad script signing.
<li>So you might aswell go for the real thing...
</ul>
</div>
<div class="slide">
<h1>One Too Many (XMPP)</h1>
<h2>Multicasting with XMPP?</h2>
<ul class="incremental">
<li>70% of S2S XMPP messages is presence updates (5 years ago)</li>
<li>XMPP has limited support for one-to-many communications</li>
<li>XMPP can be improved, but: trust problem with multicast</li>
</ul>
</div>
<div class="slide">
<h1>One Too Many (HTTP)</h1>
<h2>Multicasting with HTTP?</h2>
<ul class="incremental">
<li>fundamentally feasible</li>
<li>unnatural: HTTP is not bidirectional</li>
<li>requires trust in a federated architecture</li>
</ul>
</div>
<div class="slide">
<h1>Cross That Bridge As We Get There?</h1>
<h2>Let's just get started with something!</h2>
<ul class="incremental">
<li>The Mediocre is the Enemy of the Good</li>
<li>Historic Examples:</li>
<li>HTTP.. HTTP/NG?, SPDY!?</li>
<li>SMTP.. What? Faceboogle!?</li>
<li>XML.. What? JSON!?</li>
<!-- li>SQL..</li -->
