Quantum Escrow Ensuring Trust & Recoverability

Escrow System for QuantumExpress: Ensuring Trust & Recoverability

QuantumExpress Software offering both store and forward quantum key generation and live quantum key injection.

When I was designing an ultra secure QRNG Encryption system, I had to think of the events are unpredictable. The user may lose their keys for various reasons, some out of their control. So, I had to think about real life when you lose your combination to the safe you bought. You simply call the company you bought the safe and they send someone there to pop it open as the have a master key. Well, in this situation, you can not call me to come over and find your key.

When you setup the system, I can create an escrow system (optional) and YOU assign that to a trusting individual in your company, trusted employee with a master key to a vault that stored the keys with another layer of encryption. Here is how it works:

The escrow system in QuantumExpress is a safety and compliance mechanism designed to balance strong encryption with practical key recovery and usage traceability — especially important when working with enterprise clients, government agencies, or regulated industries.

Why quantum Escrow?

Once a file is encrypted using a 256-bit AES key derived from a QRNG (Quantum Random Number Generator), it's practically impossible to decrypt it without that key. But this ultra-secure approach poses a challenge:

So, what happens if a user loses their key file, or a key is needed for compliance, investigation, or forensic audit?

That’s where escrow comes in.

How It Works (Conceptually)

1. Key Generation:

   • When a user encrypts a file, QuantumExpress generates a 512-bit quantum key from the QRNG device.

   • The first 256 bits are used for AES-GCM encryption.

   • The full 512-bit key is saved as a .key file locally and — if enabled — a copy is encrypted and submitted to an escrow vault.

2. Escrow Vault:

   • This is a secure, offline or cloud-based repository maintained by QuantumLaso or a trusted third party.

   • Keys stored in escrow are encrypted again (double encryption) using a master key known only to the QuantumLaso operator or a secure multi-party access policy.

3. Audit Trail:

   • When a key is sent to escrow, metadata is recorded:

     • MAC address

     • Device ID

     • Timestamp

     • Hash of original file (optional)

     • User ID (if available)

4. Recovery Policy:

   • The user can request a key recovery only by verifying identity, and with proper authorization, for example via a signed request, 2FA, or NDA agreement.

   • Optionally, enterprise clients can host their own escrow server with access control.

Benefits

• Reduces the risk of total data loss

• Enables accountability in case encrypted files are involved in legal or regulatory matters

• Supports Zero-Knowledge Security: QuantumExpress never knows what files are being encrypted — only the key is stored

• Integrates with future AI-based escrow agents (to automate logging, verification, and retrieval)
