Term
Noise Protocol IK (Poket PC Handshake)
Noise IK is the handshake Poket PC uses to pair and to start every session: mutual authentication, forward secrecy, ChaCha20-Poly1305 records.
Term
Zero-Knowledge Relay
A relay that matches clients by token and forwards ciphertext without keys. How Poket PC relayd fits that model and its limits.
