Quantum Safe Login
What problem does this solve?
Today, user passwords are protected using encryption (RSA/ECC) that quantum computers will be able to break.
Attackers already:
- Steal encrypted login traffic today
- Store it
- Decrypt it later when quantum computers mature
This is called “Harvest Now, Decrypt Later” (HNDL).
Once decrypted, passwords, credentials, and identities are exposed retroactively.
What does Qubit Guard Secure Access do?
It protects user logins using post-quantum cryptography, so even future quantum computers cannot decrypt captured login data.
In simple terms: Even if attackers steal the login traffic today, it will remain useless forever.
How does this integrate with existing systems?
QuantumSafe Login is designed for drop-in deployment.
Supported deployment models
- Lightweight SDK for web, mobile, or desktop apps
- Encrypts the password client-side
- Requires no backend authentication changes.
- REST API that accepts encrypted credentials
- Ideal for centralized IAM or legacy systems
- Sits in front of existing login endpoints
- No client UI changes required
Works with
- Active Directory / LDAP
- SAML, OAuth2, OpenID Connect
- Custom and legacy IAM systems
How it works (simple explanation)
- 1. A user enters their username and password
-
2. Before the password leaves the device:
- It is encrypted using a quantum-safe algorithm (ML-KEM)
- 3. The encrypted password travels over the network
-
4. Even if intercepted:
- It cannot be decrypted now or in the future
- 5. The server safely verifies the login
- No plaintext passwords
- No reusable stolen credentials
- No future decryption risk
Client-side impact
| Scenario | Change Required |
|---|---|
| Web apps | Add SDK (minimal code change) |
| Mobile apps | Add SDK (no UX change) |
| Legacy systems | None (proxy mode) |
Performance & compatibility
- Backward compatible with existing TLS / HTTPS
- No password storage changes required
- Login latency impact: typically <5 ms
-
Works alongside:
- MFA
- Biometrics
- Smart cards
- Zero-Trust architectures
Why this matters now
- Quantum computing timelines are accelerating
- Governments require post-quantum readiness by ~2030
-
Login systems are:
- The first attack surface
- The easiest data to harvest
- The hardest to fix retroactively
Quantum-safe encryption must be applied before data is captured, not after.
What makes this different from TLS / HTTPS?
| Traditional Login | QuantumSafe Login |
|---|---|
| RSA / ECC encryption | Post-Quantum ML-KEM |
| Vulnerable to future quantum attacks | Quantum-resistant |
| Safe “for now” | Safe long-term |
| Can be decrypted later | Cannot be decrypted later |
