SimpleX Chat

+

Private & encrypted - the only platform without user identifiers!

+
+ + + + + +
+

You can download terminal chat app from GitHub or using this command:

+

+ curl -o- https://raw.githubusercontent.com/simplex-chat/simplex-chat/master/install.sh | bash + + Copy to clipboard + + +

+
+
+

Alice

+
+
+
+ +
+
+
+

Bob

+
+
+
+ +
+
+
+ +
+
+

Tom

+
+
+
+ +
+
+ + + +
+
+
+ +
+
+

Privacy redefined

+

SimpleX advantage:

+

SimpleX ensures data and meta-data privacy

+

with a new protocol design – it delivers messages

+

without using senders' and recipients' identifiers,

+

unlike any other messaging platform.

+
+
+
+

Security

+

Two-layer encryption and communication integrity

+
+
+
+

Privacy

+

Your contacts and messages are stored on your device

+
+
+
+

Convenience

+

Easy to add contacts and start talking

+
+
+
+
+ +
+
+

Problem: chat security

+ +
+

End-to-end encryption?

+

Alice sends the key to Bob (e.g. via p2p network or via chat server)

+
+
+
Alice
+ Alice sends the key to Bob +
Bob
+
+
+

Now Bob can send encrypted messages to Alice - he believes it is secure!

+
+
+
Alice
+ They believe it is secure +
Bob
+
+
+
+
+

Man-in-the-middle attack!

+

But the key can be intercepted and substituted by Tom (the attacker)

+
+
+
Alice
+ key is intercepted +
Bob
+
Tom
+
+
+

Now the attacker can read the messages without Alice or Bob knowing

+
+
+
Alice
+ attacker can read messages +
Bob
+
Tom
+
+
+
+ +
+
+ +
+
+

What is the solution?

+

+ To create secure encrypted channel you need an existing secure channel +
where you can pass the encryption key (or key fingerprint). +

+

Any alternative solution can be compromised.

+
+
+ +
+
+

Make a private connection!

+

To add contact and to start chat

+

+ Adding a contact in mobile app will require sharing your one-time QR code. +
In the terminal UI you need to share an invitation with your contact. +

+

After creating your chat profile in the app:

+
+
+

1.
Show QR code or share link

+
+ mobile app: show QR code to add contact +
+
Alice
+
+ +
+

2.
Your contact scans QR code or opens link

+
+ mobile app: scan QR code +
+
Bob
+
+ +
+

3.
A private connection is established

+
+ mobile app: confirm contact +
+
Alice
+
+ +
+

4.
Now you can chat privately!

+
+ mobile app: start chat +
+
Bob
+
+
+
+
+ +
+
+

SimpleX messaging protocol

+

Unidirectional (simplex) queues

+

+ Simplex messaging protocol + (SMP) for messaging via secure persistent queues will serve as the low level protocol for + SimpleX chat - see + demo server implementation.
+ It uses different encryption keys for each message queue - the key is passed via existing + secure channel - e.g. QR code or another simplex queue.
+

+
+ simplex messaging protocol +
+
+ +
+
+
+

Chat

+

Communication integrity

+

+ Each chat uses two (or more) simplex queues for duplex communication. Each message contains the + hash of the previous message to detect if messages are lost or changed. +

+
+ simplex chat: duplex conversation +
+
+ +
+
+
+
