End-to-End Encrypted, Peer-to-Peer First
GSTNet uses AES-256-GCM encryption to protect communication content, combined with a peer-to-peer-first architecture: direct device-to-device connectivity is preferred whenever network conditions allow.

Why WebRTC Changes Everything
WebRTC (Web Real-Time Communication) is an open standard that enables direct peer-to-peer communication between devices, minimizing reliance on a central server to relay data.
When two GSTNet users connect, GSTNet attempts to establish a direct encrypted channel between their devices. Backend infrastructure supports account management, authentication, and connectivity assistance (signaling); when a direct peer-to-peer connection can't be established due to network conditions, a secure relay may be used to maintain the connection.
Regardless of the connection path, Global Space Technology does not possess the cryptographic keys required to decrypt protected communication content.
Ephemeral Keys
New encryption keys generated for every session. Keys exist only in device memory and are never saved.
Perfect Forward Secrecy
If one session key is compromised, all other sessions remain secure. Past messages cannot be decrypted.
ICE/STUN/TURN
Industry-standard protocols ensure connectivity even behind firewalls and NAT configurations worldwide.
DTLS-SRTP
All WebRTC streams are protected by DTLS handshake and SRTP encryption — double-layered security for calls.
Next Generation Protocols
Satellite Communication
Phase 4 roadmap includes Starlink and Iridium satellite integration. Communicate from anywhere on Earth without ground-based internet infrastructure.
RF Mesh Network
Radio frequency communication for battlefield and disaster scenarios. Devices form self-healing mesh networks with no dependency on existing infrastructure.
Quantum-Ready Encryption
Post-quantum cryptography integration planned to ensure communications remain secure against future quantum computing attacks.
Does GSTNet Use Servers?
Yes. GSTNet uses backend infrastructure for account management, authentication, security and abuse prevention, entitlement management, and connectivity assistance. Communication is designed to use direct peer-to-peer connectivity whenever possible.
The important distinction: backend infrastructure does not mean Global Space Technology possesses the cryptographic keys required to decrypt protected end-to-end encrypted communication content. That protection comes from the encryption itself, not from an absence of servers.
