For decades, digital security has relied on mathematics.
Protocols like TLS and Kyber let two parties compute a shared secret key using asymmetric equations. They’re elegant and fast — but still depend on the assumption that no one can solve those equations quickly enough.
At the other end of the spectrum is quantum key distribution (QKD), where photons and physics guarantee that any eavesdropper reveals themselves. QKD is unbreakable in theory, but expensive, fragile, and hard to deploy.
ROOM Keys™ is designed for the space between —
“More secure than today’s math-based key exchange. Less exotic than full quantum.”
⚙️ What Are ROOM Keys™
ROOM Keys™ are generated from a patented hardware primitive called Read-Only-Once Memory (ROOM) — a CMOS circuit that enforces physical single-use access.
When a ROOM cell is read, it collapses within microseconds, erasing its stored value and replacing it with noise or entropy. The result is a key that exists once, never again.
That deterministic collapse is measured and timestamped, producing a verifiable event — a “physical audit trail” for key creation.
🌐 How ROOM Keys™ Work in Practice
Rendezvous — Alice and Bob connect through an ordinary HTTPS session to a ROOM-enabled rendezvous server. ROOM Release — The server reads one ROOM cell and obtains a one-time value R. The cell collapses permanently. Key Derivation — Both clients perform a post-quantum KEM (Kyber or hybrid ECDH + Kyber) to compute a shared secret S. Fusion — Each side combines the math-based S with the physics-based R using a standard FIPS-validated
HKDF: K = HKDF(IKM = S, salt = R, info = transcript)
Result — The derived symmetric key K is their ROOM Key™ — unique, unreplayable, and cryptographically strengthened by physical irreversibility.
Even a compromised or curious server can’t recreate the same R or regenerate the key once the cell collapses.
ROOM Keys™ replicate the logic of BB84 — the first quantum key-exchange protocol — but on silicon instead of photons.
In BB84, observation destroys a qubit; in ROOM, observation collapses a transistor state.
🧩 Security Profile
Freshness: Each key derives from a distinct physical event. Non-replay: Collapsed cells cannot re-emit data. Forward secrecy: Combined with Kyber/ECDH for future-proofing. Auditability: Each ROOM Key™ has a signed attestation (r_tag, timestamp, device_id). Compatibility: Integrates with FIPS-validated crypto stacks and standard HTTPS.
ROOM Keys™ aren’t a new cipher — they’re a new root of trust.
🚀 Why “Between Classical and Quantum” Matters
Stronger than classical math: Keys can’t be cloned or re-issued, even by insiders. Simpler than quantum optics: No photons, cryogenics, or fiber links — just CMOS logic and a web interface. Deployable now: Works with existing browsers, servers, and chip fabs.
✨ The Future of Trust
ROOM Keys™ mark a shift from mathematical secrecy to physical finality.
Just as transistors once replaced vacuum tubes, ROOM Keys™ replace algebraic assumptions with verifiable hardware events.
The Internet’s next generation of key exchange won’t just be post-quantum — it will be post-algebraic.
