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 start a call, GSTNet tries to set up a direct encrypted channel between their devices. Our servers help the devices find each other (signaling); when a direct connection is not possible, an encrypted relay carries the call. Messages and files are delivered through our servers in encrypted form.
Regardless of the connection path, Global Space Technology does not possess the cryptographic keys required to decrypt protected communication content.
Changing Keys
Message keys change as you exchange messages. Private keys stay on your device, protected by its secure storage.
Forward Secrecy
If one message key were ever exposed, other messages stay protected.
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
Our Phase 4 roadmap includes satellite network integration, to communicate from places without ground-based internet.
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 servers for accounts, sign-in, abuse prevention, access management, delivering encrypted messages and files, and connecting calls. Calls use direct device-to-device connections 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.
