## Presentations:
|
||||
|
||||
2018:
|
||||
- [Dezentrales Messaging](https://ccchb.github.io/presentations/decentral_messaging)
|
||||
|
||||
## Create a presentation
|
||||
Run: `hugo server -D`
|
||||
|
||||
Create a new presentation `content/<NAME>/_index.md`
|
||||
|
||||
Browser: http://localhost:1313/presentations/<NAME>
|
||||
|
||||
|
||||

|
||||

## Agenda
|

- Dezentralität
|

- XMPP - Der Standard
|
||||
- Software (Client und Server)
|
||||
- Ist der Hoster gut
|
||||
- Verschlüsselung
|

- Alternativen

|
||||
|
||||
## Dezentralität
|
||||
- **Peer-to-Peer**
|
||||
|
||||
Geräte tauschen direkt miteinander Nachrichten aus (ohne eine zentrale Componente)
|
||||
|
||||
- **Federation**
|
||||
|
||||
Kommunikation über zentrale Komponenten
|
||||
|
||||
|
||||
{{% note %}}
|
||||
**P2P**
|
||||
- Postkasten, jeder kann zum Empfänger gehen und selbst etwas in den Kasten werfen.
|
||||
(wenn es keine Post gibt)
|
||||
|
||||
**Federation**
|
||||
- E-Mail (ISP: benutzer@hoster.de)
|
||||
- Telefonnummern (Addr: hat oftmals die ersten Ziffern für sich reserviert)

|
||||
## Dezentralität
|
||||
|
||||
#### Warum notwendig?
|
||||
|
||||
- Eröffnet ein Wettbewerb
|
||||
- kleine und viele Angriffsziele
|
||||
- vor Kriminelle
|
||||
- vor Regierungen
|
||||
- alle Überwachen
|
||||
- blockieren / sperren (Zensur)
|
||||
- Verringert Missbrauch durch Vertrauen
|
||||
|
||||
{{% note %}}
|
||||
- _Eröffnet einen Wettbewerb:_ damit fortschritt
|
||||
(Gewinne gehen zum größten Teile in die USA)
|
||||
- Entscheidungen: z.B. nur noch auf Englisch, Mark Zuckerberg darf Nachrichten löschen
|
||||
- _Angriffsziele:_
|
||||
- Hacker können nicht alle Server kompromentieren
|
||||
- Regierungen können nicht
|
||||
- den Zugang zu allen Servern verlangen (NSA - Snowden)
|
||||
- alle Server blockieren (Telegram - Russland)
|
||||
- _Verringert Missbrauch durch Vertrauen_
|
||||
- **Auswirkung:** nicht alle Daten können **geklaut** oder **analysiert** werden
|
||||
- Analysiert zur Manipulation (Werbung oder politisch, siehe Cambridge Analytica)
|
||||
- **Bei Missbrauch** leichterer Wechsel

## Dezentralität
|
||||
|
||||
|
||||
#### Nachteile
|
||||
- Komplexität steigt
|
||||
- Gewollte Verringerung an Marktanteil
|
||||
- Kann auch von kriminellen Elementen genutzt werden
|
||||
- Nutzer müssen sich ggf. sich Ihre Adresse und Passwort sich merken
|
||||
|
||||
{{% note %}}
|
||||
- _Komplexität steigt:_ Da nicht nur Clients, sondern auch Server untereinander sicher (Ausfall, vertrauensvoll) kommunizieren müssen.
|
||||
- _kriminellen Elementen:_ wie bei jeder Technologie kann diese auch von Bösen genutzt werden.
|
||||
- _... sich merken:_ allerdings müssen Sie dies auch für Ihre E-Mail-Adresse, was noch Standard im Internet ist.

### Extensible Messaging and Presence Protocol (XMPP)
|
||||
|
||||
- Existiert seit 1999 (unter den Namen Jabber)
|
||||
- IETF Standard seit 2002
|
||||
|
||||
|
||||
- Google Talk 2005 - 2013 (entwickelte Jingle)
|
||||
- Facebook 2010 - 2014
|
||||
- WhatsApp nutzt es intern
|
||||
|
||||
{{% note %}}
|
||||
- Jingle:
|
||||
- Aushandlung von Datenverbindung (angelehnt an SIP)
|
||||
- für: Datenaustausch, Video/Voice-Chat, ...

||||

## XMPP
|
||||
#### Adressierung
|
||||
JID (Jabber ID) genannt:
|
||||
```
|
||||
node@domain/ressource
|
||||
```
|
||||
|
||||
URI-Format: (falls MUC mit `?join` am Ende)
|
||||
|
||||
```
|
||||
xmpp:node@domain?join
|
||||
```
|
||||
|
||||
{{% note %}}
|
||||
- MUC (Multi User Chat): Gruppenchat
|
||||
|
||||
**Als User**
|
||||
|
||||
- benutzer@server/gerät
|
||||
|
||||
**In MUC**
|
||||
|
||||
- chatraum@muc-server/nickame
|
||||
|
||||
**Transport**
|
||||
- ganz unterschiedlich

## Ist der Hoster gut
|
||||
Tools zum Testen des Servers (Auswahl an Servern)
|
||||
|
||||
- [Compliance](https://compliance.conversations.im/) ([support Alles](https://compliance.conversations.im/api/compliant_servers/) / API)
|
||||
- [Status](https://status.conversations.im/historical/) für S2S + Uptime
|
||||
|
||||
XEPs:
|
||||
|
||||
- PEP / PubSub
|
||||
- MAM (für MUC)
|
||||
- HTTP-Upload
|
||||
- DNS-SRV for TLS (HTTPS)
|
||||
|
||||
{{% note %}}
|
||||
- Personal Eventing Protocol: Geolocation, Mood, Activity, Tune
|
||||
- Message Archive Management:
|
||||
- Vorteil gegenüber: Threema und WhatsApp (mit OMEMO auch gegenüber Telegram)
|
||||
- OMEMO: Neue Geräte können alte Nachrichten nicht entschlüsseln
|
||||
- HTTP-Upload: Offline und in MUC Datenaustausch
|
||||
- "umgeht" Firewalls

### Verschlüsselung
|
||||
- Off-The-Record
|
||||
- OpenPGP
|
||||
- OX
|
||||
- OMEMO
|
||||
|
||||
Detailert: [here](https://conversations.im/omemo)
|
||||
|
||||
{{% note %}}
|
||||
- Neben TLS (SSL)

|

|
||||
|
||||
## XMPP <small>Verschlüsselung</small>
|
||||
|
||||
- Geräte erstellt **asynchrones** Schlüsselpaar
|
||||
- öffentlichen Schlüssel wird per PubSub auf dem Server hinterlegt
|
||||
- Kontakte werden durch PEP / PubSub über neuen Schlüssel informiert
|
||||
- Dieser muss diesen öffentlichen Schlüssel laden
|
||||
|
||||
{{% note %}}
|
||||
- synchrone: Entspricht einem Passwort, was allen Gesprächsteilnehmern bekannt ist.
|
||||
- asynchrone: mathematisches Verfahren mit Schlüsselpaaren (öffentlicher und privater Schlüssel)
|
||||
- Kontakte = Roster
|
||||
- den **neuen oder weiteren** öffentlichen Schlüssel
|
||||
|
||||
- Signiert und verschlüsselt
|
||||
- zurückziehen des Schlüssels

## Alternativen zu XMPP
|
||||
|
||||
#### Peer-to-Peer
|
||||
- Nutzen das Tor-Netzwerk
|
||||
- **Tox**
|
||||
- **Briar**
|
||||
- kann auch Local per Wifi und Bluetooth genutzt werden
|
||||
- ... (viele mehr)
|
||||
- libp2p
|
||||
|
||||
- (mir sonst keine Weiteren bekannt ...)

||||
|
||||

|
||||
|
||||
## Alternativen zu XMPP
|
||||
|
||||
#### Federation
|
||||
- **Matrix** (Riot):
|
||||
- Änderungsvorschläge am Protokoll werden durch das Unternehmen entschieden
|
||||
- (mir sonst keine Weiteren bekannt ...)

## Reusable slides
|
||||
|
||||
Store markdown in a [data template](https://gohugo.io/templates/data-templates/) and reuse it in multiple sections or presentations.

<br>
|
||||
<a href="#" class="navigate-down">🔽</a>
|
||||
|
||||
---
|
||||
|
||||
Add a `example` key to data/home.toml:
|
||||
|
||||
```toml
|
||||
example = "I'm a slide"
|
||||
```
|
||||
<br>
|
||||
|
||||
Set the `content` attribute to "home.example":
|
||||
|
||||
```markdown
|
||||
---
|
||||
|
||||
{{< slide content="home.example" >}}
|
||||
|
||||
---
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
💡 Each data template entry can contain one or more slides, separated by `---` with newlines.
|
||||
|
||||
---
|
||||
|
||||
💡 All other slide shortcode attributes (background, transition, etc.) can be used and will be applied to each slide in the data template entry.
