Introducing SecureBitTransport — Beyond WebRTC

[SecureBitChat]

SecureBitTransport — A New Foundation for Private P2P Communication

We’re developing SecureBitTransport,
a next-generation transport layer designed to replace WebRTC for truly decentralized, private, and serverless peer-to-peer communication.

This is an ongoing research and development effort — not yet available in the main build —
aimed at providing full privacy and Tor compatibility without relying on any external infrastructure.

Core Design Goals

• Zero-Server Operation — no STUN, TURN, or signaling servers required
• Tor & Offline Support — fully functional over TCP, Onion routing, or local sockets
• End-to-End Encryption — AES-256-GCM + ECDH-P384 + HMAC-SHA-384
• Perfect Forward Secrecy — powered by a Double Ratchet mechanism
• Metadata Protection — no IP or connection leaks, even during handshake
• User-Verified Trust — SAS / QR fingerprint confirmation instead of CA certificates
• Browser Independence — works across Tauri, desktop, and mobile environments

Why Move Beyond WebRTC

While WebRTC is widely used, it depends on components that break true privacy:

• Requires centralized ICE/STUN/TURN servers
• Relies on UDP (not available in Tor)
• Performs key exchange within the browser (DTLS control)
• Exposes IP and routing metadata through ICE candidates

SecureBitTransport eliminates these limitations —
encryption, key exchange, and routing are entirely handled by the client.
No third parties. No metadata leakage. No trust required beyond mathematics.

Future Extension: SecureBitMediaLayer

On top of the transport layer, we plan to implement SecureBitMediaLayer —
a fully encrypted framework for voice and video calls.

Planned features:

• Audio: Opus codec with adaptive bitrate
• Video: VP8 / AV1 encoding
• Frame-level AES-GCM encryption
• Jitter buffer and latency compensation
• Tor-compatible, works over TCP transport

This will enable secure, anonymous audio and video communication —
without WebRTC or centralized signaling.

Roadmap (Work in Progress)

• Define and test SecureBitTransport core protocol
• Implement encrypted data channels (text, files)
• Prototype SecureBitMediaLayer for voice and video
• Integrate into SecureBit Chat client
• Publish documentation and open threat-model review

Discussion

We’re opening this thread for community feedback and research collaboration.

• Which transport mode should be prioritized (Tor, TCP, WebSocket)?
• What codecs or crypto primitives do you recommend?
• Tools or ideas for fuzzing and security testing?

🧡 Philosophy: privacy, decentralization, and cryptographic transparency.
Secure communication should never depend on infrastructure — only on mathematics.
