This document specifies the UDP Datagram Privacy Network (UDPN) protocol, version 1.0. UDPN provides an authenticated, encrypted Layer 3 tunnel over UDP with traffic obfuscation designed to resist deep packet inspection (DPI) and active probing. All packets are wrapped in DTLS 1.2 ApplicationData records. The protocol uses the Noise_NK handshake pattern with X25519 Diffie-Hellman and ChaCha20-Poly1305 AEAD encryption.
