Noise Protocol Framework

Protocolo P2P

Cryptographic meta-framework for constructing secure two-party handshake and channel protocols based on Diffie-Hellman key exchange. Provides a pattern language for composing authenticated key establishment (AKE) protocols supporting mutual/optional authentication, identity hiding, forward secrecy, and zero round-trip encryption. Not a full protocol itself — a framework other protocols implement at the session/crypto layer. Widely adopted: WhatsApp, WireGuard, Lightning Network, I2P.

Termos Public domain
Fundos N/A
Baseado Em Signal Protocol (design philosophy); NaCl Cryptobox; Diffie-Hellman key exchange
Arquitetura P2P Two-party session establishment — provides authenticated key establishment for any P2P or client-server architecture; does not define a network topology
Rede de Sobreposição N/A — session/handshake layer only

Local-First N/A — session-layer primitive
Criptografia de Ponta a Ponta (E2EE) Yes — mutual authentication, identity hiding, forward secrecy, zero-RTT encryption
Biblioteca de CRDTs N/A
Tolerância a Falhas Bizantinas N/A — no network-layer BFT; session security only
Assinatura Yes — ECDH-based static and ephemeral key exchange; ed25519 / X25519
Permissões Key-based (static public key as capability; PSK extension available for pre-shared key layer)
Compatibilidade com a Web Semântica No
Contrato Inteligente No
Posição na Pilha de Protocolo Session/crypto layer — operates below application protocols and above transport; provides authenticated key establishment for any P2P session
Incorporação de Ativo / Valor None — cryptographic session framework only; no value or asset transmission
Maturidade / Padronização do Protocolo Mature / De Facto Standard — specification stable since revision 34 (2018); adopted by WhatsApp, WireGuard, Lightning Network, I2P; academic security proofs published; not submitted to formal standards body
