Ed25519 Asymmetric Authentication

Every voice transmission is signed by the broadcaster's Ed25519 cryptographic key pair. Participants cryptographically verify the origin of every voice frame, mathematically preventing frequency spoofing, channel hijacking, or impersonation.

SFrame End-to-End Voice Encryption

Every voice frame is encrypted on the speaker’s device with SFrame (AES-128-GCM authenticated encryption) using a per-channel key derived client-side. The SFU relay forwards ciphertext only — it never holds the key. AES-GCM is hardware-accelerated on modern phones, desktops, and browsers, so encryption adds no noticeable battery or CPU cost.

Deterministic PTT Channel Arbitration

CipherWire eliminates conversational collisions with millisecond-precision Push-to-Talk arbitration. Configurable priority tiers allow incident commanders and dispatchers to instantly override non-critical channel chatter.

Decentralized Mesh & Relay Fallback

If central internet backhauls go dark, CipherWire nodes automatically establish local peer-to-peer ad-hoc mesh networks using mDNS and UDP hole-punching, ensuring operational continuity in austere environments.
