Company Introduction

BASESTONE is a quantum security company that generates unpredictable one-time quantum keys from 
QRNG-based quantum entropy and 
distributes them securely via post-quantum cryptography (PQC). Its Quardian suite—authentication, 
communication encryption, and key 
management—realizes a true Zero Trust security architecture.

Introduction of item

1. Quantum Key Management System

[Quardian - Quardian KMS]
A key management system that generates and manages 256-bit one-time quantum keys from QRNG-based 
entropy. It supports key 
generation, rotation, lifecycle/audit logging, and failure resynchronization, distributing keys to each agent 
over a PQC (Kyber) channel.

2. Quantum Multi-Factor Authentication

[Quardian - Quardian Auth]
This quantum-random-based MFA solution combines FIDO2/passkeys with biometric authentication, 
issuing a fresh, one-time quantum key 
(QKey) for each authentication. Since authentication is generated directly on the user's device without key 
sharing, credentials cannot be 
forged even if the server is compromised—enabling a seamless passwordless and OTP-free login.

3. Quantum-secured VPN

[Quardian - Quardian Trust]
Quardian Trust is a quantum-resistant channel security solution that protects communication links by 
centrally and automatically 
managing the lifecycle of QRNG-based quantum keys. It integrates seamlessly with public, financial, and 
enterprise infrastructures, 
enabling a stable and sustainable response to future security threats and regulatory changes.
