Overview

Glacier Core VPN leverages the WireGuard protocol to provide secure, high-performance, and lightweight VPN connections. It ensures fast encryption, minimal attack surface, and robust security by utilizing modern cryptographic primitives. All Glacier Core Servers operate as immutable infrastructure, are launched via automation, and securely distribute key material to client devices.

WireGuard Protocol: Technical Breakdown

WireGuard is a next-generation VPN protocol designed to be:

• Simple and minimalistic – Only a few thousand lines of code, reducing attack vectors.
• Performant – Implements cryptography in the kernel for low latency and high throughput.
• Stateless and connectionless – Uses a roaming mechanism based on UDP packets.
• Modern cryptographic suite – Employs cutting-edge cryptographic algorithms:
  • ChaCha20 – Symmetric encryption
  • Poly1305 – Message authentication
  • Curve25519 – Key exchange
  • BLAKE2s – Cryptographic hashing
  • SipHash24 – Hashed key lookup
  • HKDF – Key derivation function

WireGuard establishes VPN tunnels using public-key cryptography, replacing traditional certificate-based authentication. Each device has a pair of cryptographic keys, where public keys authenticate peers, and private keys establish secure sessions.

Glacier Core Server Architecture

• Immutable Infrastructure – Each Glacier Core Server is stateless and deployed via Infrastructure-as-Code (IaC) to prevent configuration drift.
• Automated Deployment – Servers are provisioned dynamically with automated key material distribution to clients.
• No Persistent State – Each reboot ensures a pristine state, reducing attack surfaces.

Key Material Distribution

• Glacier Core VPN automatically generates and distributes key material to authorized client devices.
• Keys are rotated periodically and on demand, enforcing secure session management.
• Zero-touch provisioning ensures seamless onboarding for managed devices.

Quantum-Resistant Key Generation (Optional Feature)

For high-security environments, administrators can enable quantum-resistant key material generation.
