WireGuard VPN Protocol
Also known as: WG
WireGuard is a modern VPN protocol using Curve25519 (X25519) for key exchange, ChaCha20-Poly1305 AEAD for encryption and BLAKE2s for hashing, running over UDP with a minimal state machine. It is increasingly used for management-plane access, roaming test rigs and private 5G site-to-site connectivity, offering lower complexity and attack surface than IPsec/IKEv2 stacks.

WireGuard in context
Telecom networks depend on Internet-style routing (BGP, DNS, MPLS) for interconnect, transport and application delivery. Route hijacks and DNS abuse can degrade or intercept signaling as easily as any application-layer attack, which is why RPKI and DNSSEC are now standard hardening for carrier networks.
To place WireGuard in the wider telecom-security picture, review WEP, 3G, Decryption, Digital Signature, IDS and IP Address.
