Mute

Mute is a privacy enhancing communication system.

Features

• End-to-end encryption.
• Communication with forward secrecy (keys required to decrypt past messages are frequently replaced and destroyed).
• Establish forward secret communication with first message (no synchronous two-way handshake).
• Asynchronous communication between peers.
• Authenticity of the identity-key relationship is established and preserved.
• Human-readable/human-memorizable identities.
• Communication with established standards where possible (e.g., using SMTP as the transport protocol).
• Sending messages and changing the state of one's own identity requires payment by the user to both finance the system and to limit SPAM.
• Better-than-nothing anonymity: mixing/delaying of messages to prevent simple discovery of sender-recipient relationship by third party passive observer.
• Both sender and recipient anonymity.
• Plausible deniability of message content and some deniability of communication relationship.
